Title: Magneto-optical recording method
Inventor: HASE TAKUYA
IPC: G11B11/10
Filed: 1989-11-10
Abstract: PURPOSE:To rewrite a record in succession without needing rotational delay of a magneto-optical disk by recording a half of a sector to be recorded, leaving the remaining half under an erased state, recording the next new information and erasing the recorded sector simultaneously. CONSTITUTION:The magnetization direction of the magneto-optical disk having an even number of sectors is set in advance in a magnetization direction under the nonrecording state, and an external magnetic field in the opposite direction to this magnetization direction is impressed, while odd number or even number sectors are irradiated in turn with a modulated laser light pulse to perform the recording. When information is further recorded after recording information in all nonrecorded sectors, the external magnetic field is impressed first, and also the recorded sectors are DC-wise irradiated with laser light, and the sectors corresponding to information are irradiated in turn with the modulated laser light pulse. Thus, since the nonrecorded sectors can immediately be turned into the recordable state, the overwrite of information is feasible without needing rotational delay for the erasing purpose.

Abstract: PURPOSE:To record information onto an optical disk or to reproduce the information out of the disk with high stability and high accuracy, by using a triangular wave signal generator having the power proportional to the laser beam power and converting a servo error signal into a PWM signal by a triangular wave to drive an actuator.

Then a triangular wave V having a level proportional to the beam power is provided by means of the signal sent from the means 4 and generating the prescribed beam power. The waveform V is compared with an error signal (e) of the servo system by the comparator 7 and therefore the pulse width of the PWM signal MS delivered from the comparator 7 can be set adversely proportional to the laser beam power. Thus the proper open loop gain is obtained in response to the laser power supplied in a recording/reproducing mode or an erasion mode.
