Abstract

PURPOSE:To obtain an optical recording disk provided with a guide signal having high sensitivity, by forming a recording film consisting of an organic thin film containing a prescribed coloring matter, on the surface of the disk on which a guide signal whose projecting and hollowed parts are reversed in the characteristic is formed in advance. CONSTITUTION:On a substrate 701 consisting of a flat polymer plate, a guide signal bit 707 whose projecting and recessing parts are opposite in the characteristic are formed in a guide signal section 710 by means of press molding, etc. On the substrate 701, a metallic vapor-deposited film of Al, etc. or an interference reflection film 705 is provided, on which a collodion solution admixed with a solution of about 5% polymethine compound coloring matter in the ratio of one to one, whose main solvent is, for instance, ethyl alcohol and other is dropped and dried, by which a thin film 702 whose thickness is about 0.75mum is formed. Since the organic film 702 formed on the projecting part of the guide bit 707 is thin, intensity of a reproducing light beam of the guide signal is modulated enough, and also the sensitivity of an information recording section 711 is high enough. In this way, a recording disk provided with a guide signal having a high sensitivity is obtained.
