Title: Optical disk device
Inventor: HAYASHI HIDEAKI
IPC: G11B21/10
Filed: 1993-12-25
Abstract: PURPOSE:To obtain a servo operating range immune to the flaw of a disk by performing servo while switching a servo gain with a detecting means of which time constant is changed. CONSTITUTION:The reduction of reflected light from an optical pickup part 1 is detected by a level detection part 2. When the slight level reduction from the envelope of the peak level of reflected light is detected, the detection part 2 outputs a command D1 to a gain varying switch 6 and reduces the loop gain of servo. When the level reduction larger than it is detected, a command D2 is outputted to a hold switch 4 and a servo error signal is held. Therefore, the servo gain is lowered before the disturbance of noise is increased in the servo error signal and afterwards, the reduction of level is held by the detection so that the deviation during it can be reduced. Further, the noise of the flaw is reduced, the servo is stabilized, and a hold block can be shortened.

IPC: G10K9/12
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To prevent ear-offensive noise from being superposed on a buzzer sound. SOLUTION: When frequency-division ratio data are written to a counter/ timer register 530, a counter/timer circuit 534 divides the frequency of the oscillation signal of an oscillation circuit by the value indicated by the frequency- division ratio data. When output acknowledgement data are written to a port-B register 536, an envelope generating circuit 538 outputs a variable gain control signal. The variable gain control circuit 540 varies the amplitude of a frequency- division signal by a value corresponding to the voltage of the variable gain control signal. When output stop data are written to the port-B register 536, the envelope generating circuit 538 does not output the variable gain control signal any more. The variable gain control circuit 540 stops amplitude control over the frequency-division signal.
