Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an information recording/reproducing apparatus, and more particularly to an audio apparatus for automatically reproducing or playing back music and automatically recording the music reproduced in a storage device when an information recording medium storing music information recorded is loaded into a reproducing device for reproducing it. 
     2. Description of the Related Art 
     An audio apparatus such as an in-vehicle audio apparatus has a storage-medium reproducing device such as a CD player, so that a user can enjoy the music reproduced or played back by the reproducing device. The audio apparatus also has a hard disk (hereinafter referred to as HD) with a large capacity of e.g. several tens G (giga) bytes and a hard disk drive (HDD) for driving HD, so that the user can enjoy any selected music program reproduced by a music reproducing system from the HD in which a large number of recording media such as CDs are copied (see JP-A-2000-207845). 
     According to such an audio apparatus, if contents of a large number of recording media, e.g. CD have been previously recorded in a built-in HD, a preferred piece of music read from among programmed pieces of music contained in a large number of CDs can be enjoyed with no loading/unloading thereof. Particularly, from the viewpoint of safety driving, this is preferred in an in-vehicle audio apparatus, which is mostly operated during driving because copying in HD makes it unnecessary to load/unload a recording medium such as CD. 
     In this way, in the in-vehicle apparatus, contents of a large number of CDs are often used in a form recorded in a storage device such as HD. Some audio apparatus, therefore, have been also proposed in which the reproducing/recording of CD is automatically started when CD is loaded into a reproducing device. 
     SUMMARY OF THE INVENTION 
     When the recording/reproducing of the recording medium is automatically started when the recording medium is loaded into the reproducing device, audio of the recording medium is not output from a reproducing system. For this reason, a user may forget recording and eject the recording medium. This gives rise to a problem that the recording medium will be ejected without completing recording. 
     Further, in the case of the audio apparatus appended to a car navigation device, when the operation/display panel of the car navigation device is opened, the recording medium such as CD is ejected. Therefore, when the user forgets that recording is being automatically performed and opens the operation display panel, a problem likewise occurs that the recording medium will be ejected without completing the recording. 
     Further, if music is not output from the recording system during automated recording as described above, the user does not notice that sound skip has occurred. Therefore recording will be completed in sound-skipped state. In this case, it is possible to detect the sound-skip and automatically perform re-recording. This, however, leads to a problem that the recording time will be lengthened without the user&#39;s noticing. Another problem will occur in the automated recording that if the user is not seeing the display panel, he/she cannot know when the recording has been completed. 
     Further, it is also possible to output music being reproduced during the automated recording. However, the user, who often records content of a recording medium such as CD into a built-in HD in advance and enjoys his/her preferable programmed music from the built-in HD, may carry out automated recording while he/she listens to broadcasting from a tuner. In such a case, simultaneously when the recording operation is started, the recording medium is reproduced and the reproduced audio is produced. After completion of the recording, therefore, it is necessary for a user to return the source of audio output from a speaker to the state where the recording medium has been loaded. This is very troublesome. 
     The invention has been made in view of the problems described above. An object of the invention is to provide an information recording/reproducing apparatus capable of preventing a recording medium from being ejected during automated recording of the recording medium and saving a user&#39;s labor during the automated recording. 
     In order to achieve the above-described object, an information recording/reproducing apparatus (1) includes a reproduction unit, an operation unit, a storage unit, and a control unit. The reproduction unit reads information recorded in a recording medium. The operation unit instructs the reproduction unit to eject the recording medium. The storage unit stores the information read by the reproduction unit therein. When the recording medium is loaded into the reproduction unit, the control unit controls the reproduction unit to read the information and controls the storage unit to store the information read by the reproduction unit therein automatically. When the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit informs a user that the storage unit is storing the information read. 
     In addition to (1), in an information recording/reproducing apparatus (2), when the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit displays time to storage completion on a display. 
     In addition to (1), in an information recording/reproducing apparatus (3), when the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit displays attribute information of the information, which has been stored in the storage unit, on a display. 
     An information recording/reproducing apparatus (4) includes an operation/display panel, a reproduction unit, a storage unit, and a control unit. A recording medium is lodable into the reproduction unit, when the operation/display panel is opened. The reproduction unit reads information recorded in the recording medium. The storage unit stores the information read by the reproduction unit. When the recording medium is loaded into the reproduction unit, the control unit controls there production unit to read the information and controls the storage unit to store the information read therein automatically. When an opening operation of the operation/display panel is performed during the storage unit being storing the information read, the control unit informs a user that the storage unit is storing the information read. 
     In addition to (4), in an information recording/reproducing apparatus (5), when the opening operation of the operation/display panel is performed during the storage unit being storing the information read, the control unit displays time to storage completion on a display. 
     In addition to (4), in an information recording/reproducing apparatus (6), when the opening operation of the operation/display panel is performed during the storage unit being storing the information read, the control unit displays attribute information of the information, which has been stored in the storage unit, on a display. 
     In addition to any one of (1)-(6), in an information recording/reproducing apparatus (7), when the storage unit completes the storing of the information read, the control unit ejects the recording medium from the reproduction unit automatically. 
     In addition to any one of (1)-(6), in an information recording/reproducing apparatus (8), when an error occurs during the storage unit being storing the information read, the control unit notifies the occurrence of the error. 
     An information recording/reproducing apparatus (9) includes a reproduction unit, a storage unit, an audio output unit, a control unit, and a reception unit. The reproduction unit reads information recoded in a recording medium. The storage unit stores the information read by the reproduction unit therein. The audio output unit outputs audio. The reception unit receives external information from external. When the recording medium is loaded into the reproduction unit, the control unit controls the reproduction unit to read the information and controls the storage unit to store the information read therein automatically. The audio output unit is able to output the external information received. When the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit controls the storage unit to begin storing the information read without changing the audio output from the audio output unit. 
     An information recording/reproducing apparatus (10) includes a reproduction unit, a storage unit, an audio output unit, a control unit, a reception unit, and a selection unit. The reproduction unit reads information recorded in a recording medium. The storage unit stores the information read by the reproduction unit therein. The audio output unit outputs audio. The reception unit receives external information from external. When the recording medium is loaded into the reproduction unit, the control unit controls the reproduction unit to read the information and controls the storage unit to store the information read therein automatically. The audio output unit is able to output the external information received. The selection unit selects one of: (a) a first mode in which when the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit controls the storage unit to begin storing the information read without changing the audio output from the audio output unit; and (b) a second mode in which when the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit changes the audio output from the audio output unit to the information read. 
     According to the information recording/reproducing apparatus (1), when the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit informs a user that the storage unit is storing the information read. Therefore, even if a user erroneously performs the operation of ejecting the recording medium, the user recognizes that the information is being stored, thereby continuing the storage. For example, if the user sees a display during the automated recording, it can be prevented that the user erroneously instructs to eject the recording medium. 
     According to the information recording/reproducing apparatus (2) or (3), when the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit displays time to storage completion or attribute information of the information, which has been stored in the storage unit, on a display. Therefore, a user can know the remaining time until completion of the storage at that time or e.g. song names of music storage-completed. 
     According to the information recording/reproducing apparatus (4) to (6), likewise as described above, when an opening operation of the operation/display panel is performed during the storage unit being storing the information read, the control unit: informs a user that the storage unit is storing the information read; displays time to storage completion on the display; or displays attribute information of the information, which has been stored in the storage unit, on the display. Therefore, even if a user erroneously performs the operation of opening the operation/display panel, the user can recognize that the information is being stored and know e.g. song names of the music storage-completed at that time. 
     According to the information recording/reproducing apparatus (7), when the storage unit completes the storing of the information read, the control unit ejects the recording medium from the reproduction unit automatically. This saves the labor of the operation by the user. 
     According to the information recording/reproducing apparatus (8), when an error occurs during the storage unit being storing the information read, the control unit notifies the occurrence of the error. Therefore, the user can select whether the storage should be interrupted or the storage should be continued. 
     According to the information recording/reproducing apparatus (9), when the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit controls the storage unit to begin storing the information read without changing the audio output from the audio output unit. Therefore, for example, even when the storage is performed while the user listens to broadcasting from a tuner, the user can continuously listen the broadcasting of the tuner without performing the operation of changing the audio output. 
     According to the information recording/reproducing apparatus (10), the selection unit selects one of: (a) a first mode in which when the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit controls the storage unit to begin storing the information read without changing the audio output from the audio output unit; and (b) a second mode in which when the recording medium is loaded into the reproduction unit and the audio output unit outputs audio other than the information recorded in the recording medium, the control unit changes the audio output from the audio output unit to the information read. Therefore, the audio to be output during the storage can be previously set according to a user&#39;s request, so that the operation during the storage can be simplified.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Now referring to the drawings, an explanation will be given on an audio apparatus according to the invention with taking an embodiment where the invention is applied to a car navigation device.  FIG. 1  is an appearance view of the car navigation device. As seen from  FIG. 1 , an operation/display panel  2  is provided on the front face of an device body  1 . At the center of the operation/display panel  2 , an LCD display portion is arranged. On the periphery thereof, plural operation keys  4  are provided. 
     When opening the operation/display panel  2  is designated through the pertinent operation key  4  or a touch panel of the LCD display portion  3 , the operation/display panel  2  descends with rotating. Then, a recording medium insertion portion (not shown) of a CD player or MD player appears so that the recording medium can be inserted thereinto. 
       FIG. 2  is a schematic diagram showing the configuration of a control system of the car navigation device. In  FIG. 2 , only audio-related portions are shown. As seen from  FIG. 2 , the audio-related portions of the car navigation device include a CPU  11 , a ROM (Read Only Memory)  12 , a RAM (Random Access Memory)  13 , a HDD  14 , an encoder  15 , a decoder  16 , a CD-ROM drive  17 , an MD drive  18 , a tuner  19 , a selector  20 , an amplifier (AMP)  21 , a speaker  22 , a display portion  23 , a display controller  24 , an entry portion  25 , a graphic controller  26  and a graphic memory  27 . These elements are connected to one another through a bus  28 . 
     The CPU  11  controls the respective hardware portions of the car navigation device through the bus  28  and executes various programs on the basis of programs stored in the ROM  12 . The ROM  12  previously stores the various programs necessary for the operation of the car navigation device. The RAM  13  may be e.g. an SRAM, which stores temporary data generated during execution of the programs. 
     The HDD  14  drives HD that is a storage medium for storing music recorded in a recording medium such as CD. The encoder  15  compresses a signal supplied from the recording medium such as CD, and the compressed signal is stored in the HD. The decoder  16  decodes the signal read from the HD, and then the decoded signal is output. Further, the CD-ROM drive  17 /MD drive  18  reproduces and outputs music information recorded in the CD/MD. The tuner  19  receives and outputs audio broadcasting such as FM, AM and a television broadcasting. The selector  20  selects audio to be output from the speaker  22 . Under the control by the CPU  11 , the selector  20  selects one of: (a) read-output of the HDD  14 ; (b) output of the CD-ROM drive  17 ; (c) output of the MD drive  18 ; and (d) output of the tuner  19  to output the selected one to the AMP  21 . Then, the selected audio is output from the speaker  22 . 
     The display portion  23  displays a map, the operating status of the car navigation device, or operation screens for various functions. The display portion  23  includes a large-scale LCD display portion (large-sized display screen)  3  provided on the operation/display panel  2  shown in  FIG. 1 , and is controlled by the display controller  24 . A touch panel switch is provided on the LCD display portion  3 . When an item segment displayed on the LCD display portion  3  is depressed, the corresponding item can be selected or the corresponding function can be executed. The entry portion  25  includes the operation keys  4  provided on the operation/display panel  2  and the touch panel on the LCD display portion  3 . 
     The CPU  11  controls the graphic controller  26 . The graphic controller  26  reads out content displayed on the display portion  23  from the graphic memory  27 , and sends the contents read to the display controller  24 . 
     The audio apparatus of this car navigation device has an automated recording function that when a CD is loaded in the CD-ROM drive  17 , the CD is automatically reproduced and the reproduced output is automatically stored in the HD by the HDD  14  through the encoder  15 . Further, the audio apparatus is configured so that an operation mode of the output produced from the speaker  22  during the automated recording can be set. Specifically, the audio apparatus can select: mode  1  in which the automated recording is started without changing audio being output from the speaker  22  at the time of loading CD, e.g. broadcast output from the tuner  19 ; or mode  2  in which the automated recording is started with changing audio being output from the speaker  22  to the reproduction output of the CD-ROM drive  17 . At the time of the mode selection, a user makes the LCD display portion  3  display a menu thereon and select audio output mode setting with using the operation keys  4 . By depressing “mode  1 ” or “mode  2 ” displayed on the screen of the audio output mode setting at the LCD display portion  3 , either mode can be set. The output operation mode set by a user can be stored in the RAM  13 . 
     Referring to the flowchart of  FIG. 3 , an explanation will be given on an operation when music information recorded in CD is automatically recorded in the HD. Incidentally, this operation is performed under the control of the CPU  11  on the basis of the program stored in the ROM  12 . 
     In the case of automated recording, when a user designates the opening of the operation/display panel  2  from the operation keys  4  or touch panel on the LCD display portion  3 , the operation/display panel  2  descends with rotating. Then, the recording medium insertion portion of the CD-ROM drive  17 /the MD drive  18  appears. In this state, when a user loads CD in CD loading portion (the recording medium insertion portion) of the CD-ROM drive  17 , the CPU  11  initiates a program shown in the flowchart of  FIG. 3 . 
     When CD is loaded, the CPU  11  closes the operation/display panel  2  and thereafter starts the reproduction of the CD by the CD-ROM drive  17 . The music information reproduced by the CD-ROM drive  17  is automatically recorded in the HD by the HDD  14  through the encoder  15  (step  101 ). Next, the CPU  11  determines whether or not the audio output mode (output operation mode), which is set by a user and stored in the RAM  13 , is the mode  2  (step  102 ). If the audio output mode is the mode  1 , audio being output from the speaker  22  at this time, e.g. broadcast output from the tuner  19  is continuously output as it is. On the other hand, if the audio output mode (output operation mode) set by the user is the mode  2 , the CPU  11  reproduces the music information recorded in the HD by the HDD  14  and also controls the selector  20  so that the output from the selector  20  is changed into the output from the decoder  16  (Step  103 ). Thus, the music information is automatically recorded in the HD and simultaneously, the music information stored therein is read and supplied to the speaker  22  through the decoder  16 , selector  20  and AMP  21 . In this way, the music recorded in the CD output from the speaker  22 . 
     Next, the CPU  11  controls the graphic controller  26  and the display controller  24  to display the output operation mode such as “CD is being reproduced”, “FM broadcasting”, etc. according to the output operation mode set as described above (step  104 ). 
     The CPU  11  determines whether or not a user designates the operation of ejecting the CD or the operation of opening the operation/display panel  2  through the operation keys  4  or touch panel on the LCD display portion  3  during the automated recording (step  105 ). If the ejecting operation or the panel opening operation is performed during the automated recording, the CPU  11  controls the graphic controller  26  and the display controller  24  to display message indicating that the recording is not still completed on the LCD display portion  3  as shown in  FIG. 4 , thereby informing a user that the recording is now being performed (step  106 ). 
     On the other hand, CD previously digitally stores music signals in a programming area for each track and TOC (Table of Contents) information such as information indicating a position of each track in a lead-in area. During CD reproduction, the CPU  11  first reads and stores the TOC information in the RAM  13 . The TOC information contains numbers of respective pieces of music in the CD and their playing times. The CPU  11 , therefore, calculates the remaining playing time and the recording-completed music number when the ejecting operation is performed, thereby displaying them on the screen indicating “recording not-completed”, as shown in  FIG. 4 . On this screen, the CPU  11  also displays icons “YES” and “NO” for allowing a user to select whether or not the automated recording is interrupted. 
     Next, the CPU  11  determines which “YES” or “NO” has been depressed on this screen (step  107 ). When a user depresses “YES” on this screen, the CPU  11  interrupts the automated recording (step  108 ), and then the operation/display panel  2  is opened and the CD is ejected (step  109 ). Thereafter, the program is terminated. When a user depresses “NO” on the screen indicating “recording not-completed”, the CPU  11  returns to step  105 , and then the automated recording is continued. 
     On the other hand, in step  105 , if the CPU  11  determines that the ejecting operation or the panel opening operation has not been performed, the CPU  11  further determines whether or not sound skip (data skip) has occurred (Step  110 ). The CPU  11  always checks the data number (address) of the CD data that is being reproduced by the CD-ROM drive  17 . When the data number has greatly changed, the CPU  11  determines that the sound skip has occurred. In this case, the CPU  11  controls the graphic controller  26  and the display controller  24  to display a message indicating the occurrence of the sound skip and icons for selecting the recording interruption (step  111 ). 
     The CPU  11  determines which icon “YES” or “NO” has been depressed on this screen (step  112 ). When a user depresses “YES” on this screen, the CPU  11  interrupts the automated recording (step  113 ), and then the operation/display panel  2  is opened and CD is ejected (step  109 ). Thereafter, the program is terminated. When a user depresses “NO” on this screen, the CPU  11  returns to step  105 . 
     In step  110 , if the CPU  11  determines that the sound skip has not occurred, the CPU  11  further determines whether or not the recording has been completed (step  114 ). If not completed (NO), the CPU  11  returns to step  105 . If completed (YES), the CPU  11  opens the operation/display panel  2  and ejects CD (step  109 ). Thereafter, the program is terminated. 
     As described above, in the case where the ejecting operation or the panel opening operation is performed during the automated recording of the music information of CD, a user is reminded that the recording is being performed. Therefore, the recording interruption against the user&#39;s will can be prevented. Also in the case where the sound skip occurs, user&#39;s attention is called. Therefore, the automated recording accompanied with sound skip can be prevented. 
     In the embodiment described above, the example is explained where the audio output mode for the automated recording can be selected. However, the function of selecting the audio output mode may not be given. Namely, during the automated recording, audio being output at that time can be continuously output without outputting reproduced audio of the recording medium. 
     In the embodiment described above, when the ejecting operation has been performed or the sound skip has occurred during the automated recording, the message for calling the user&#39;s attention is displayed on the LCD display portion  3 . However, the audio apparatus may inform the user of the fact that the recording being performed or the occurrence of the sound skip by voice. 
     Further, in the embodiment described above, the audio apparatus according to the invention is applied to the car navigation device. However, the invention can be applied to an ordinary audio apparatus equipped with a CD player and MD player. Further, the invention can also be applied to an audio apparatus equipped with the CD player alone or the MD player alone. 
     Further, in the embodiment described above, music information of CD is recorded in the HD. However, the invention can be applied to a case where music information is automatically recorded from various recording media into various storage devices other than HD. The invention can be applied to a case where information contained in a recording medium includes various information such as music and an image.
