Toshiba Corp. has developed a rewritable optical disc with a capacity of 30GB per layer, per side and a companion read/write optical head that incorporates a blue laser, the company announced today.

A rewritable optical disc. First used in drives by Panasonic in the late 1980s, the phase change technology was subsequently employed in all major optical drives, including CD-RW, DVD-RW ...

Phase change optical recording is a challenging technology for data storage that is used for CD and DVD rewritable discs. It is based on localized laser induced heating of a thin layer to cause a ...

A team of researchers at Taipei’s National Taiwan University (NTU) have developed a prototype rewritable optical disc that can store 100GB of information and is compatible with existing CD and ...

Chalcogenide phase-change materials are the key components used for rewritable optical discs, and improving the speed of imprinting information is of significant commercial interest. Much effort ...

You’re done with optical discs as a means of data and media delivery, or soon will be. But when done right, as it has been with Millenniata’s M-Disc, optical has a particular advantage ...

TOKYO–May 9,2003–Toshiba Corporation announced that it has developed a working prototype of a high-capacity. dual-layer, single-sided, blue-laser-rewritable optical disk. The new disk enjoys key ...

Toshiba has developed a dual-layer rewritable optical disc for use with the blue-laser-based AOD (Advanced Optical Disc) format that it is developing with NEC. The disc — which will be ...

An earlier removable, rewritable optical disk that also used magnetic technology. Introduced in 1985, magneto-optic (MO) media and drives are no longer manufactured. Refurbished drives and media ...

The reversibility of the crystallization–amorphization process allows fabrication of rewritable memory. A paradoxical situation exists when a device such as an optical disc is functional and ...

Burning a pinpoint of dye with a laser changes its optical properties to mimic those of a stamped pit, in effect recording data onto the disc. Recordable and rewritable media differ only in the ...
