Title: Magneto-optical recording system
Inventor: TOKITA TOSHIAKI
IPC: G11B7/125
Filed: 1992-04-08
Abstract: PURPOSE:To eliminate the trouble that irradiation with a laser is insufficient when a medium moving speed is further increased with the magneto-optical recording system which executes ovwritable magneto-optical recording by subjecting the magneto-optical recording medium constituted of single layer of perpendicularly magnetized film to irradiation with the laser while changing irradiation conditions under a specified external magnetic field. CONSTITUTION:The intensity distribution of the laser in the medium moving direction on the medium surface is changed at the time of forming magnetic domains and at the time of erasing the magnetic domains. The laser intensity distribution of the laser is so set that the range relatively wider than the range at the time of erasing the magnetic domains is irradiated with the laser at the time of forming the magnetic domains particularly in the case of the execution of the magnetic domain formation by using the laser of a long pulse width. The laser, then, reaches the wider range in the medium moving direction at the time of forming he magnetic domains. Then, the problem of the insufficient time for irradiation is eliminated even in the case of the use of the laser having the wide laser width. The sufficient dealing with the medium speed is thus possible.
