Filed: 1995-03-31
Abstract: PURPOSE: To obtain an optical disk having a structure producing an effect similar to that in the case of an increased difference in reflectance of a VO2 film used as a reproduction assisting layer and varying reflectance even when laser beam of shorter wavelength than the conventional wavelength is used. CONSTITUTION: An underlayer 2, a VO2 film 3, a dielectric layer 4, a reflecting layer 5 and a protective film 6 are successively laminated on a transparent substrate 1 with previously formed information pits to obtain the objective optical disk 10.
