OPTICAL INFORMATION RECORDING MEDIUM

摘要

PURPOSE:To use inexpensive materials to constitute a DRAW type optical disk having the reflectivity which can be reproduced with a compact disk player and laser disk player. CONSTITUTION:A film is formed of org. dyes having real number part Nabs=2.2 to 3.0 of complex fractive indices and virtual real number Kabs<1.0 at 800 to 1300Angstrom as a light absorption layer 2 on a substrate 1 having light transparency. An AlN 3 film is formed at >=150Angstrom and <=1500Angstrom on this light absorption layer 2 and further, an Al reflection film 4 is formed at >=500Angstrom on this AlN film.
