Title: Optical disk reproducing device
Inventor: SHIMOI YASUYOSHI
IPC: G11B19/247
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To improve the average transfer velocity of data while sufficiently taking advantage of the performance of a driving mechanism and a signal processing circuit by comparing constant linear velocity rotation error data and constant angular velocity rotation error data and controlling the changeover of a selector in such a manner that the rotating speed is made smaller. SOLUTION: A CLV(constant linear velocity) control circuit 6 outputs the difference between the velocity obtd. from a frame synchronization signal period and the velocity determined by an instruction from outside as CLV rotation error data. A CAV(constant angular velocity) control circuit 9 outputs the difference between the velocity obtd. from an FG signal period and the velocity determined by an instruction from outside as a CAV rotation error data. The selector 10 subtracts the CAV rotation error data from the CLV rotation error data and selects the CLV system if the result is positive. If the result is negative, the selector selects the CAV system and sends either of the rotation error data via a D/A converter 11 to a driver 12. As a result, the inner peripheral part of the disk is subjected to rotational control by the CAV and the outer peripheral part thereof by CLV.

Thereby, the disconnection of the electrode wirings due to stress migration can be prevented and a semiconductor device, which is high in integration and is provided with a highly reliable wiring, is obtained.
