Title:
DEVICE FOR REPRODUCING OPTICAL DISK AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3871358
Kind Code:
B2
Abstract:
PURPOSE: To stably reproduce data even when a servo error signal is varied in an optical disk and also when the servo error signal is changed due to a temp. change of an optical pickup and a detecting amplifier for an error signal.
CONSTITUTION: When an ant. of a reproducing data read out of the optical disk 1 and stored in a memory 6 at the time of reproducing data is detected by a controller 7 to be the amt. by one rotation or more of the optical disk, writing of reproducing data into the memory 6 is interrupted, and an optical pickup 3 is controlled to jump over to a reproduced track by the controller 7, and a servo gain control or a servo offset control signal is sent to a servo circuit 8. After performing focus servo or tracking servo control on the optical pickup 3 by this servo circuit 8, the write interrupted position on the optical disk 1 is detected, and the data reproducing operation is resumed.
