Definitions

  • the ultraviolet curable resin layer has an uneven shape or a guide groove which forms a data recording signal.
  • FIG. 2 is a diagram schematically showing a method for manufacturing an optical disc of the present invention.
  • FIG. 3 schematically shows a specific embodiment of the optical disk of the present invention, together with FIGS. 4 to 8, and this figure has a multilayer structure having a thin cover layer and one surface of the disk.
  • FIG. 3 is a diagram showing a structure of an optical disc adapted to perform recording and reproduction from a side of a cover layer.
  • FIG. 2 is a diagram showing a structure of an optical disc capable of performing recording and reproduction from both sides of the disc.
  • the other of the above-mentioned bonded type optical discs for recording and reproducing from one side is composed of two disk substrates 2 each having a multilayer structure 4 and a multilayer structure 4.
  • the lamination layer 13 By laminating on the formed side and using the lamination layer 13 as an optical intermediate layer, recording and reproduction can be performed on all signal layers by irradiating a laser beam from one side. This is the optical disk 1E.
  • a urethane-acrylic UV resin 6a is dropped on the stano at 99, and the thickness is made uniform by spin coating (30 000 rpm for 30 seconds). At this time, the thickness of the UV resin 6a is, for example, 2 m. Thereafter, ultraviolet rays are irradiated for 5 seconds with a mercury lamp or a halogen lamp to cure the UV resin 6a (step C).
  • a pressure-sensitive adhesive sheet 5a having a thickness of 25 m is attached to the disk substrate 2 (step B). As shown in FIG. 9, this pressure-sensitive adhesive sheet 5a is obtained by attaching a protective cover 14 to a sheet of the pressure-sensitive adhesive sheet 5a previously punched into a predetermined disc shape.
  • a large number of polyethylene sheet mounts (transportation sheets) are arranged on the sheet 15 and are bonded to the disk substrate 2 by pressure bonding with a silicon rubber pad described later ( Process B
  • Step E an aluminum film is formed by sputtering while adjusting the transmittance with a film thickness of 20 to 40 nm.
  • one of the disks is formed by bonding disk substrates provided with a multilayer structure to each other and using a layer formed by bonding as an intermediate layer. Since recording and reproduction to all signal layers are performed from the side of, the capacity can be increased as compared with the case where the multilayer structure is single-sided.

Abstract

L'invention concerne un disque optique constitué d'une structure multicouche dans laquelle une couche de signal de substrat est formée sur un substrat, et au moins une couche composite constituée d'une couche intermédiaire et d'une couche de signal est à nouveau formée sur la couche de signal du substrat, la couche intermédiaire étant constituée d'une couche en résine durcissable aux ultraviolets et d'une couche de feuille d'adhésion.
