Filed: 1988-02-19
Abstract: PURPOSE:To improve the deterioration in an output level and deterioration in spurious radiation by providing a high frequency SAW oscillator and an SAW filter group constituted to select one wave in generated signals from the oscillator and mixing a narrow band signal with one wave of the signals selected by the SAW filter group. CONSTITUTION:An output frequency of a comb-line generator 3 and an output frequency (F3+mF'3) from a high frequency SAW oscillator 13 selected by a switch 11 are mixed by a 1st mixer 4 and the result is sent to a band-pass filter 5. The filter 5 passes only a signal of F3 +mF'3-mF2 being its pass frequency and gives it to a 2nd mixer 6. Thus, the 2nd mixer 6 mixes its signal (F3 +m(F'3-mF2)) and a signal F1 from the narrow band oscillator 1 to output a signal or F1 +F3 +m(F'3--mF2). After other undesired wave is eliminated by a band-pass filter 7 and given to a 3rd mixer 10. Thus, a controller 9 is used to apply switching control to a signal of the high frequency SAW oscillator 13 and the SAW filter group 12 to obtain a broad band frequency.

IPC: G11B19/14
Filed: 1987-02-23
Abstract: PURPOSE:To attain the mechanism simplification of a disk protecting device without giving load to a head holding mechanism by moving a head to the outside of a recording area and at the same time releasing a contact state between the head and a disk in case these head and disk are kept under the stationary states and a mutual contact state for a long period of time. CONSTITUTION:A head 20 is moved toward an arrow head 15 within a recording area 24a by a head shift means 16 and performs the recording/reproducing jobs or an erasing job. Then a period of time during which the head 20 keeps contact with a disk 24 in a stationary state is counted by a measuring means 31 after the final recording job is performed, i.e., the disk 24 is revolved. In case said counted time is large with no recording/reproducing job done yet and the disk 24 is not ejected, the means 16 moves the head 20 to the outside of the area 24a after receiving a signal from the means 31. In such a constitution, an exclusive drive source is not needed and the mechanism of a disk protecting device can be simplified without giving any adverse influence to the head 20, etc.
