Filed: 1989-04-07
Abstract: PURPOSE:To attenuate the disturbance of a detecting signal when a light spot stretches over a track at the high speed into a definite range and to prevent the misdetection of a focus abnormality by adding a band restricting means to a focus abnormal operation control system. CONSTITUTION:The laser beam 21 is reflected by a disk 25, it is split by a splitter 23, it is converged to a bisected focusing photodetector 27, and a part of the beam is converged to a bisected track photodetector 29 by a prism 28, respectively. The output of the photodetector 27 drives an actuator 34 through a differential amplifier 31, a phase compensating filter 32 and a power amplifier 33, and a lens 24 is focus-controlled. A signal based on a pregroup 25a of the disk 25 is light-received by the element 29, it is guided through a differential amplifier 35, a phase compensating filter 36 and a power amplifier 37 to the actuator 34, and the lens 24 is tracking-controlled. A focus detecting signal is guided through an LPF 39 to a window comparator 38, it is compared with positive/negative reference voltage, and when the focus is off and a comparator emits an 'L', a prescribed action corresponding to the focusing abnormality is executed.
