OPTICAL INFORMATION RECORDING MEDIUM AND METHOD OF RECORDING/REPRODUCTION FOR IT Russian patent published in 2013 - IPC G11B7/243

Abstract RU 2488178 C2

FIELD: information technologies.

SUBSTANCE: information recording medium comprises multiple information recording layers. The layer of information recording does not contact with the substrate and has the composition expressed by the formula [(ZnS)_x(SiO₂)_1-x]_y(Sb_zX_1-z)_1-y, where 0<x≤1.0, 0.3≤y≤0.7, 0.8≤z≤1.0, and X represents an element selected from the group made of Ga, Te, V, Si, Zn, Ta, Sn and Tb.

EFFECT: higher stability of medium characteristics with course of time, higher sensitivity and speed of response for a laser beam.

2 cl, 8 dwg
