Title: Tracking controller
Inventor: KAMIKAWA YUTAKA
IPC: G11B7/09
Filed: 1989-06-27
Abstract: PURPOSE:To make an optical head from being hardly deviated from a substantial track by providing a defect detection means varying an amplification factor of 1st and 2nd variable amplification factor amplifiers at the detection of a defect and an adder adding outputs of the variable amplification factor amplifiers and giving the result to the driver. CONSTITUTION:A defect detector 5 detects an abnormality state when a defect exists on a disk, and the output is fed to a p3 terminal of a pseudo tracking signal generator 7 and fed to variable amplifiers 8,9 as a control signal. When the defect is detected to be present, the amplification factor of the variable amplifier 8 is increased and the amplification factor of the variable amplifier 9 is decreased to increase the rate of the output of pseudo tracking signal based on the loop filter output signal studied at the preceding time and to decrease the rate of the loop filter output and the result is fed to the driver via an adder 10 thereby making the track hardly to be deviated from the track. Even when a defect exists on the disk, the pickup is hardly deviated from the correct track.

Title: Reproduction level control method of digital recording and reproduction
Inventor: TOMIZAWA SHINROU
IPC: G11B20/10
Filed: 1982-09-20
Abstract: PURPOSE:To prevent the deterioration of S/N of a reproduced sound and at the same time to ensure an optimum level of reproduction, by recording the reproduction level information of digital information in a redord mode and controlling the reproduction level of digital information in accordance with the reproduction level in a reproduction mode. CONSTITUTION:In a record mode the audio signal of the music to be recorded to an audio disk is turned into the digital audio information through pulse code demodulation. This audio information is recorded together with the reproduction level information of the corresponding music. Then in a reproduction mode, the recorded digital audio information and reproduction level information are read by a pickup and at the same time distinguished from each other by a processing circuit 4. Then a switch 8b is changed over via a reproduction level information processing circuit 5 to vary the gain of an amplifier 8a. Thus a reproduced sound having a level corresponding to the original sound level of a record mode is obtained. This prevents the deterioration of S/N of a reproduced sound and at the same time ensures the reproduction of an optimum level.

Abstract: PURPOSE:To improve the real time performance of the system by rotating a token sequentially from a station with less link data sent by each station to eliminate a wait time thereby reducing a communication time of the link data. CONSTITUTION:A link control unit of a master station makes exchange of link parameter with a sequence control unit and suppose that the allocated quantity of link data in each station in the parameter is stations 3, 5, 4, 1, 6, 2 in the smaller order. Then the master station generates a rotation table based on the parameter. Then stations other than the master station confirm a range of link data sent by its own station and to which station a token is to be sent by sending the parameter and the table to all the stations. Then the token is rotated from a station having less transmission range of link data sequentially. When the reception of the link data is finished, the transfer to an internal buffer is finished. Thus, time wait is eliminated and the real time performance is improved.
