摘要： PURPOSE:To increase the C/N ratio of a magneto-optical disk by annealing the polycarbonate substrate at a specified temp. so as to suppress double refraction in the intrasurface direction of the substrate. CONSTITUTION:A polycarbonate substrate for a magneto-optical disk having 137 deg.C glass transition point is annealed at 137+ or -7 deg.C to suppress double refraction in the intrasurface direction due to strain produced during molding and to reduce the depth of a groove. As a result, the difference in level is reduced, reflected light is intensified and the C/N ratio of a detection signal can be increased. Annealing at =145 deg.C is not suitable because polycarbonate softens. When a magneto-optical medium is formed on the annealed substrate in the form of a film, the characteristics can be improved.

摘要： PURPOSE:To improve a production yield by enabling control of an increase of an error rate even if a transfer mold is used repeatedly, by making use of the transfer mold whose temperature has been risen through irradiation of ultraviolet rays by cooling the transfer mold down to a temperature at a value prior to the irradiation of the ultraviolet rays. CONSTITUTION:Ultraviolet curing resin 3 is piled up on a guide groove 2 of a transfer mold 1 made of nickel. Then, positioning is performed by mounting a transparent base on the same and the transparent base is pressed. Then, the ultraviolet curing resin 3 is cured by irradiating ultraviolet rays to the same. In this instance, the irradiation is performed by restoring the transfer mold 1 to the normal temperature by cooling the transfer mold 1 at every use or the transfer mold 1 is fitted to cooling equipment such as water cooling equipment. Therefore, even if a process is repeated by making use of the same transfer mold 1, viscosity of the ultraviolet curing resin 3 to be formed in the guide groove can be kept at 100-200 CPS (centripoise) and the generation of bubbles can be prevented.

The recording layer 2 is formed by film-depositing and successively laminating a lower base layer 2d, a magnetic recording layer 2c, a reflection layer 2b and an upper base layer 2a by a sputtering method. The upper and the lower base layers 2a and 2d are made of SiN, for example, the magnetic recording layer 2c is made of TbFeCo, for example, and the reflection layer 2b is made of aluminum, for example. The moisture non-permeable film 3 is formed by film-depositing SiN, for example, by a sputtering method. SiN has light transmissivity and moisture non-permeability. The temperature deformation preventing film 4 is formed by applying a modacrylic UV curing resin, for example, by a spin coating method and then curing the resin by UV irradiation.

摘要： PURPOSE:To shorten the adhering time between disks and hubs by mounting hubs of a projecting type and recessed type respectively to two sheets of veneer disks by using a UV curing resin, and then sticking the two disks to each other. CONSTITUTION:A 2p film 7 is formed on a glass substrate 6 and a recording film 8 is deposited thereon. The disk part to be shielded by the hub is masked to prevent the deposition of the film 8 thereon, then the film is deposited at this time, by which the veneer disks 11, 12 are obtd. The UV curing resin 19 is then applied between the disk 11 and the hub 4 of the projecting type and is irradiated with UV rays from the disk 11 side after centering, by which the resin 19 is cured. The hub of the recessed type is similarly fixed to the disk 12. An epoxy resin adhesive agent 3 is in succession applied between the disks 11 and 12 respectively fixed with the hubs 4, 5 and the hubs 4, 5 are fitted. The adhesive agent 3 is cured by spending time.
