Abstract

PURPOSE:To increase recording density with ease of tracking, by recording repetitive bit during peak level period and eliminating to record and bits at video signal period. CONSTITUTION:A video signal generator 12 including a TV camera or the like generates a video signal, which is applied to a recording semiconductor laser 11 to make on/off control for recorded laser light. In this case, laser light with a level which can not be recordable is irradiated from a playback semiconductor laser 11' at all times, a recorded playback disc 6' is reproduced from a photodetector 4, and the light is applied to a video signal generator 12 with separation to synchronize the video signal and it is inserted to a blank period 23. Recording is avoided during a peak level period 2 by turning off the recording laser 11. Thus, since the synchronizing signal is recorded on a recording/playback disc, tracking can be made easily.
