The signals obtained from dual-layer optical disks were analyzed experimentally and theoretically with emphasis on reducing layer cross talk (LCT) and spherical aberration (SA). Using the dual-layer phase change optical disk, the DC element of the LC

The domain transfer phenomenon has been applied to light intensity modulated overwrite in order to obtain large power margin. By applying a suitable magnetic field to the multilayer before readout, recorded domains on the memory layer are transferred

Overwrite repeatability of exchange‐coupled multilayer for light‐intensity‐modulated overwrite (OW) was studied by using Arrhenius analysis. A computer simulation showed that typical OW disks and a conventional nonoverwrite (NOW) disk have simi

A microcellular recording film is proposed to prevent material flow due to multiple overwriting in phase-change opticaldisks. The GeSbTeCo recording film, divided into cells of approximately 20-30 nm in diameter, is prepared by sputter-etching using

Single-beam overwriting up to 105 times has been achieved in phase-change optical discs with GeSbTeCo recording films.1 Major limiting factors of the number of overwriting cycles include local thickness change and void generation in recording films.2

In the magnetically induced super resolution, a rapid change in the readout signal was observed. The rapid change is explained by a domain collapse model. We proposed a new readout technique which utilizes the rapid change in the signal. The techniqu

In the light intensity modulated overwriting method with exchange coupled multilayers, the erasing area surrounds the writing area because the erasing temperature is lower than the writing temperature. Therefore, the data on the adjacent track might
