A new type of front aperture detection using magneto-static coupling was studied. Recording marks were copied by magneto-static coupling instead of exchange coupling. To enlarge readout power margin, a TM rich switching layer having low Curie tempera

Magnetically induced super resolution (MSR) is one of the most promising way to achieve high recording density for MO. We reported a unique MSR method called R-MSR, that utilized magnetization reversal at high temperature area. In the R-MSR, super re

Influence of interference layer that is located between substrate and magnetic layer was studied in FAD structure. The Kerr ellipticity of reflection light could be decreased by using larger thickness than that of minimum reflectivity. This lead to c

Reversal magnetically induced super resolution (R-MSR) makes use of magnetostatic coupling, which is a very weak force, in contrast to exchange coupling. To avoid the disturbance by the unexpected external field during readout (H r ), methods for imp

By means of hydrogen gas chemical sputtering of a graphite target, we have succeeded in the preparation of high insulating diamond-like-carbon (an a-C: H) film by RF- and DC-power. A noteworthy point is that the film can be prepared quite easily by a

An a-C:H film was prepared for the first time by H2 gas reactive rf-sputtering of a graphite target onto low temperature (room temperature ∼150°C) substrate. This film has a uniform amorphous structure and an H-atom ratio of 0.8 H/C; its electrica
