Three types of multiple-layer structure are proposed for a two-wavelength-compatible phase-change optical disk that uses an 830-nm beam for writing and erasing and a 670-nm beam for reading. Each disk with an optimized structure exhibits high-enough

We have successfully grown strontium barium niobate (SBN) single-crystal fibers doped with up to 0.5 wt% of Ce by the laser-heated pedestal growth method. Their photorefractive properties were investigated systematically as a function of Ce concentra

Two media fabrication methods are developed in order to improve the data-transfer rate of optical disks. One is a beam-scanning method for multispiral pregroove recording. A sixfold spiral pregroove with a 1.6-µm spacing can be recorded with this me

A multispiral pregrooved disk has been fabricated by the beam scanning method. In this method, a recording laser beam is scanned by a galvanomirror to trace the multispiral subcircle while the disk continuously moves. It is demonstrated that a 1.6-mi

The effect of oxide precipitate in Czochralski‐grown silicon crystals on minority‐carrier lifetime was investigated. The oxide precipitates, generated by heterogeneous nucleation in as‐grown crystals were found to decrease the lifetime. On the

A new tracking guide for optical disks formed by photodarkening of As–Se–S–Ge amorphous film has been developed. The tracking error signal intensity of the tracking guide was comparable with that of conventional pregrooved disks. Using an As–

A pregrooved disk is fabricated by dry etching of the silicon oxide film deposited on the glass substrate. The disk has a uniform groove depth and a smooth surface, which enables stable tracking operations and high quality playback of prepits signal.

A new method for fabricating a concentric pregrooved disk has been developed. In this method, a recording laser beam is scanned by a galvano mirror to trace a concentric circle while the disk moves continuously. Because a pregroove is recorded within
