An electron beam recorder (EBR) has been confirmed to have high-resolution performance and we think it is a promising recorder to produce a master stamper for the next-generation high-density optical disks. Because the high-density groove recording d

We report a novel nonvolatile dual-layered electrolytic resistance memory composed of a conductive Cu ion activated layer and a thin insulator for the first time. An ON/OFF mechanism of this new type memory is postulated as follows: Cu ions pierce th

We have fabricated a plasma-etched lens about three times larger than our previous design by using a novel selectivity control technique during transfer processes, and performed phase-change optical recording for the digital-video-recording (DVR)-blu

A feasibility study of a magneto-optical(MO) disk for an NA 0.85 system is presented. The disk noise level in this system was relatively large compared to the conventional NA 0.55 system at the recording density corresponding to this spot size. Two m
