MAGNETOOPTIC RECORDING MEDIUM

摘要

A magnetooptic recording medium in which recorded information can be read out from an area smaller than a beam spot by irradiating the medium with a light beam while applying an external field during reproduction comprises a magnetic recording layer for recording/holding information, a magnetic reproduction layer provided on the magnetic recording layer on the incident side of light beam, a nonmagnetic layer provided on the magnetic recording layer on the side opposite to the magnetic reproduction layer, and a magnetic assist layer provided on the nonmagnetic layer. The magnetic assist layer has a coercive force weaker than the external field being applied while recording or reproducing information.
