Abstract: An optical multiple-scanning device has a number of scanning laser light beams that scan along a scan path, are separated along the scan path by a predetermined pitch P, and produce an illumination spot of diameter D along the scan path. A synchronizing signal generating circuit for the optical multiple-scanning device includes a single photodiode and a signal processing circuit. The single photodiode has a width W along the scan path and generates a signal with maximums IMAX and minimums IMIN. If the condition W.ltoreq.P-D/4 is met, or if IMIN is less than or equal to 80% of IMAX, the signal processing circuit accurately generates a square-wave synchronizing signal such that successive rectangular pulses of the synchronizing signal cyclically indicate that successive scanning laser beams have reached a predetermined position along the scan path.

Abstract: During playback of data from a recording medium, a light source emitting a light beam incident on the recording medium is driven by a first drive circuit. During this time, a first control circuit produces a control signal to the first driving circuit and controls the first drive circuit such that a power of the light beam is kept constant. During recording of data, on the other hand, a second drive circuit supplies a drive current in superimposition on a drive current from the first drive circuit with a timing corresponding to the recording data. During this time, the control of the first drive circuit by the first control circuit is inhibited. However, the control signal immediately before the inhibition is held, and hence the light source is continually driven by the first drive circuit. Thus, only a single reference level is necessary for the power control, permitting a simplification of the construction and cost reduction of the apparatus.

Abstract: A playback signal from an optical disk includes a track cross component which is produced when a head traverses tracks on the disk and a recorded area component produced when the head passes an area on the tracks on which data is recorded. The recorded area component is especially affected by a high frequency signal. A control signal which includes the recorded area component but not the track cross component is generated by adjusting the high frequency signal. A gain of a tracking servo control is controlled by the control signal.
