Title: Optical recording medium
Inventor: UEDA YUTAKA
IPC: G11B7/246
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a sufficient track error signal by forming a light absorbing layer from a dye membrane formed by a vapor deposition method and making the max. absorption wavelength shorter than the wavelength of laser beam for recording and regeneration. CONSTITUTION:A light absorbing layer 2, a reflecting layer 3 and a protective layer 4 are successively laminated to a substrate 1. Since the light absorbing layer 2 is provided by a vapor deposition method, even when a thick film is formed, said film does not fill the grooves of the substrate like a film provided by a spin coating method. Therefore, a track error signal is ensured. Since the max. absorption wavelength of a dye membrane is shifted from the wavelength of laser beam for recording and regeneration, the dye membrane has proper transmissivity and can obtain high reflecivity by multiple reflection interference effect. The material of the light absorbing layer is composed of a dye susceptible to vapor deposition and pref. formed into a vapor deposition film whose max. absorption wavelength is shifted from the wavelength of laser beam on a short wavelength side. Further, absorption in the wavelength region of laser beam is required to a certain extent.
