Optical information recording member comprising Au, TeO2 and Te

摘要: Disclosed is an optical information recording member which permits of at a high speed and density by means energy light or heat, as well reproduction the recorded information. The has thin film formed on substrate made TeOx constituted mixture Te TeO 2 with small amount Au being added such that contents Te, O in falls within predetermined region limited terms atomic percent. invention having Te-O-Au system to be quite short time thus allowing compared conventional system. also brings about higher sensitivity C/N ratio. Further, may have thermal diffusion layer metal heat conductivity than film, least one side thereby making uniform stabilizing bits. In consequence, undesirable distortion bits prevented even when excessively large power irradiated, affording wider adaptability member.
