Title: Magneto-optical eraser
Inventor: FUJII YOSHIO
IPC: G11B5/02
Filed: 1989-04-28
Abstract: PURPOSE:To initialize magneto-optical media including both-surface media and to erase information without deforming a substrate by providing a magnetic field producing means which applies a magnetic field in normal or opposite directions whether the top surfaces of the magnetic recording media are irradiated with flash light or the reverse surfaces are irradiated with the flash light. CONSTITUTION:A flash light source 2 irradiates a medium 3 with the light for an extremely short time. Only one magnetic layer in the medium 3, therefore, absorbs light energy mainly to rise in temperature. Then the time of the light irradiation is extremely short, so the energy absorbed by the magnetic layer is a little and the substrate does not deform. In the period wherein the temperature of the magnetic layer rises, the magnetic layer is applied with the magnetic field stronger than a decreased coercive force to uniform the magnetism of the magnetic layer in normal direction, thereby performing medium initialization and information deletion. Further, flash light sources 2 are provided on both sides of the medium film surfaces and the magnetic field producing means applies the magnetic field in the opposite magnetic field application directions when the top surface of the magnetic recording medium 3 is irradiated with the flash light and when the reverse surface is irradiated with the flash light, so the initialization of the both-surface medium and the information erasure are enabled.
