Optical recording medium comprising organic dye thin film

Abstract

This invention provides an optical recording medium complying with the DVD standards, having high sensitivity, possessing high dye film stability, having a high C/N ratio during high density recording, and being capable of reducing jitter components contained in reproduced signals, by finding an organic dye thin film and a medium configuration which can be adapted for a short wavelength semiconductor laser (wavelength 500 to 700 nm) and which are satisfactory in optical characteristics, and chemical, photochemical, physical and thermal stability, the optical recording medium comprising at least a recording layer and a metallic reflecting layer laminated on the surface of a grooved resin substrate transparent to laser light; wherein the recording layer comprises an organic thin film consisting essentially of a styrylcyanine dye of a specific structure and adapted for a short wavelength laser.
