Abstract
A magnetically induced superresolution (MSR) readout method using an in-plane magnetization mask was investigated. The magnetooptical disk consisted of an interference layer, a readout layer, a transparent intermediate layer, a recording layer and a protective layer. The use of the readout layer enabled center aperture detection which was suitable for a mark edge readout system. In this investigation, the film thickness of the readout layer was 20 nm, so the polar Kerr rotation angle is enhanced because of optical interference. The use of the interferential MSR readout method with an in-plane magnetization mask enabled excellent readout and recording characteristics to be obtained.
