マスメモリー用光ディスク記録材料

抄録

A heat-mode laser recording was classified to the optical disc, the laser COM and the material transfer of the dye for the lithographic printing use.
In this review, the optical disc that would be used for mass-memory system was discussed from the recording material point of view and the discussions were concentrated on the mechanism of the heat-mode laser-recording on the evaporated tellurium film.
The optical disc system has many advantages of a large information capacity, a low cost per bit and a rapid access time. The recording materials for the optical disc system are required to have a high recording sensitivity, a high resolution, a long stability of images, a rapid access of retrieval and a cheap bit-cost.
The properties and the merits of the image-recording layer were discussed on the metal, the metal particles dispersed in the matrix and the dye dissolved in the polymer binder.
