Title: Recording method for magneto-optical memory
Inventor: TANAKA FUJI
IPC: G11B11/105
Filed: 1986-07-28
Abstract: PURPOSE:To shorten rerecording time by applying an alternate magnetic field as an external magnetic field and turning on a laser light source corresponding to a recording area in which the direction of the alternate magnetic field coincides with the contents of recorded data. CONSTITUTION:An alternate magnetic field H is applied to the recording areas N-3-N-1, N+1-N+3 of a magneto-optical memory 1 and the laser light corresponding to the recording area in which the direction of the alternate magnetic field H coincides with the contents of recording data DAT out of plural laser light sources 2, 3 is turned on to radiate a laser beam LB2 or LB3 and magnetize the recording area of the memory 1 in accordance with the recording data.
