Abstract

PURPOSE:To enable the stable detection of a tracking signal with an optical information recording carrier of a direct-read-after-write DRAW type by incorporating a specific stabilizing agent into an optical recording layer and protective layer consisting of a thermoplastic resin. CONSTITUTION:The optical recording layer 3 consisting of a dye compsn. is formed on track grooves 2 of a transparent substrate 1 consisting of an acrylic resin, etc., and further, the protective layer 6 is provided thereon. The optical recording layer 3 is constituted of a dye such as anthraquinone dye and the stabilizing agent of 10-50wt.% thereof. Metal chelate compds., arom. amines, etc., are used for the stabilizing agent. The protective layer 6 is constituted by incorporating 1-50wt.% stabilizing agent which is the same as the above- mentioned stabilizing agent into the thermoplastic resin such as ethylene/vinyl acetate copolymer. The deterioration of the dye molecules by the projection light on the track grooves 2 is thereby prevented and the stable detection of the tracking signal is enabled.
