RECORDING METHOD FOR OPTICAL DISK

摘要

PROBLEM TO BE SOLVED: To eliminate the timing deviation of amorphous marks and the shift of regenerative signal pulses by executing post-erasing recording with the pulse trains of the frequency higher than a recording frequency. SOLUTION: Driving is executed at pulse 600Mhz at the time of irradiating the surface of a medium with a laser 50mW. The amorphous marks 11 are recorded in correspondence to recording pulse trains 1 and pulsed signals are obtd. based on the analog reproducing signals. Further, erasing and recording are executed by pulse train driving, by which one-beam overwriting recording is obtd.
