Title: Erasing method in magneto-optical recorder
Inventor: MATSUBAYASHI NOBUHIDE
IPC: G11B11/105
Filed: 1990-02-16
Abstract: PURPOSE:To lengthen the life of a light source, and to erase surely the information of a desired track by erasing recorded information by making the power P1 of a preceding beam and the power P2 of a following beam lower than the recording layer PW and in addition, higher than reproducing power PR. CONSTITUTION:The recording, the reproducing and the erasing of the information are executed for a revolving magneto-optical disk 12 by using a 2-beam laser diode array as the light source 11. In this case, providing the recording power of the preceding beam at the time of the recording is made PW, and the reproducing power of the following beam is made PR, the recorded information is erased by making the power P1 of the preceding beam and the power P2 of the following beam PW>P1, P2>PR. Thus, the burden of the preceding beam can be lightened, and the life of the light source can be lengthened, and simultaneously, the occurrence of defocusing can be suppressed effectively, and residual erasures or the miserasure of an adjoining track never occurs, and the information of the desired track can be surely erased.
