A new MO (magneto-optical) disk has been developed as a new memory for digital still cameras, named “iD (image/intelligent disk) PHOTO”. Advantage of the iD PHOTO disk is a larger recording capacity of 730 MB, than those of semiconductor memories

We have developed a new MO(Magneto-Optical) disk, which is named iD(image/intelligent disk) PHOTO, as a promising candidate for a digital still camera memory. The iD PHOTO disk achieves 730MB/disk in a 50.8mm diameter by adopting some techniques main

A stacked volumetric optical disks (SVOD) system has been developed to achieve an over 1 Tbytes cartridge capacity using a commercialized drive and conventional recording layers. To confirm the reliability of thin optical disks in SVOD, several feasi

As one of the most promising schemes for high density MO recording, a new media for magnetic multivalued recording has been proposed. By switching the external field on four levels, the quadri-valued signal was obtained. On the MMV media, field sensi

For high-density and high-speed magnetooptical (MO) recording, the use of magnetic multi-valued (MMV) MO media has been proposed. [rf:1] A quadri-valued recording has been achieved using this media and a field modulation recording method. For practic

Write/erase cyclability for mark-edge recording is studied using rare-earth element[RE]-rich TbFeCo media. Mark-edge jitter for the (1-7) random pattern is small enough even after millions of cycles of data writing and erasing.

In order to elucidate the defect structure of the perovskite-type oxide solid solution La1−xSrxFeO3−δ (x = 0.0, 0.1, 0.25, 0.4, and 0.6), the nonstoichiometry, δ, was measured as a function of oxygen partial pressure, PO2, at temperatures up to
