Title: Tracking controller
Inventor: NAKAGAKI HARUSHIGE
IPC: G11B7/09
Filed: 1985-07-19
Abstract: PURPOSE:To prevent the noise of a tracking actuator due to the transmitting characteristic of a disk from arising by smoothing the reproduction signal frequency characteristic of a photoelectric transducer output through a waveform equalizing circuit correcting provisionally a disk transmission frequency characteristics. CONSTITUTION:The waveform equalizing circuits 8 and 9 act as to correct the frequency characteristic of the photoelectric transducer outputs (a) and (b), that is, the transmitting characteristic of the disk. By passing provisionally the photoelectric transducer output through the waveform equalizing circuits 8 and 9 correcting the disk transmitting characteristic, the frequency characteristic of the reproduction signal is smoothed, and therefore the amplitude of the reproduction signal can be unified irrespective of the frequency even if it lies between music on the disk. Moreover the occurrence of the noise dependent upon a conventional synchronizing signal period can be prevented from a tracking error signal obtained by envelope-detecting and comparing two subspots even if they have a signal detecting time difference.

In the same manner as mentioned above, a multistage go-ahead movement can be made. If the change lever is moved to the corresponding go-astern position, the go-ahead-and-astern change gear is moved so as to make a go-astern movement, and in this case, the position of the cam arm 23 is not changed, and therefore, a multistage go-astern movement can be achieved.
