Title: Tracking control device
Inventor: IIDA MAKOTO
IPC: G11B7/09
Filed: 1990-11-14
Abstract: PURPOSE:To achieve tracking control with a good control characteristic by providing a means for delaying a preceding beam voltage which is a first output of an optical head and by obtaining a tracking error signal by calculating the difference between the output and a succeeding beam voltage which is a second output of the optical head. CONSTITUTION:Since there is a time difference in inrush to a scratch between a preceding beam and a succeeding beam, a preceding beam voltage 10 is delayed by a delay means 3 and the time difference is eliminated, thus eliminating a phenomenon where a positive pulse is generated at a tracking error signal at the time of inrush. Also, when escaping from the scratch, the preceding beam first escapes from the scratch and then the succeeding beam escapes from the scratch. Since there is a time difference when the preceding beam and the succeeding beam escape from the scratch, the preceding beam 10 is delayed by the delay means 3 and the time difference is eliminated, thus eliminating a phenomenon where a negative pulse occurs in the tracking error signal when escaping from the scratch, thus obtaining a device with an improved controllability.

IPC: G11B19/20
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent ovaerlapping of noises on the power supply of a motor drive circuit when an operating mode is moved to a standby mode. SOLUTION: When an enable signal ENA is changed from a high level to a low level and a stepping motor 1 is changed from an operation mode to a standby mode, a capacitor 37 starts charging, and the current of a current mirror circuit provided at the front stage of drive transistors 4, 5, 6 and 7 is gradually decreased by the increase in terminal voltage of the capacitor 37. Thus, the regenerative current when the drive transistors 4, 5, 6 and 7 are finally turned off becomes smaller than the conventional value. Therefore, the ovalapping of noises on the power supply can be prevented.
