Title: Servo control circuit of information reproducer
Inventor: KIMURA SHIYUUICHI
IPC: G11B21/10
Filed: 1982-08-28
Abstract: PURPOSE:To improve the vibration resistance of tracking control and to ensure the stable tracking control, by increasing the gain of a servo control system only when the vibration is applied to an information reproducer. CONSTITUTION:A subtractor 30 is used to obtain a tracking error detecting signal which has a low level in a normal state when no vibration is applied to an information reproducer and then has a high level when the vibration is applied to the information reproducer. A variable gain amplifier 31 is connected to the output terminal of the subtractor 30. Thus a servo control system is obtained. The amplifier 31 receives the tracking error signal from the subtractor 30 and supplies a driving current corresponding to the error detecting signal to a driving means 8. When the level of the error detecting signal is higher than the positive reference voltage +e or lower than the negative reference voltage -e, the positive voltage, i.e., a comparison output is obtained at the output terminal of a level comparator 39 or 40. As a result, an objective lens is driven to reduce greatly a track jump or out-of-focus phenomenon.
