  • Publication number: 20200202895
    Abstract: Conventionally, in making a double-sided optical disc by attaching recording substrates to each other via an ultraviolet curable adhesive layer, there was a problem that the ultraviolet curable adhesive layer was slow to cure. It is thought that this is because the out gases leached from the recording substrate disturbed the cure reaction of the adhesive layer. In contrast, in the optical disc of the present disclosure, it is possible to cure the adhesive layer in a short time in attaching the recording substrates to each other via the ultraviolet curable adhesive layer, by providing a gas barrier layer at an attachment surface of a substrate to inhibit out gases from leaching from the substrate to the ultraviolet curable adhesive layer.

  • Patent number: 8009341
    Abstract: In a holographic information recording and reproducing apparatus, an optical fiber guides a reference beam toward a recording medium for holographic recording, and a precision rotator is turned, so that the reference beam is incident on the recording medium at different angles and interferes with a data-carrying signal beam to complete the recording of holographic information on the recording medium. To reproduce the holographic information, the optical fiber guides a reading beam, and the reading beam is incident on the recording medium at an angle the same as the reference beam for the recording to reproduce the holographic information stored on the recording medium. With the optical fiber and the precision rotator, a simplified light path system and a wide range of incident angles for the reference and reading beams may be achieved, and the transmissive, reflective, and 90-degree holographic storage techniques may be integrated in one single apparatus.

  • Publication number: 20100297381
    Abstract: A method for improving read stability of optical recording medium is disclosed. In the method, the thickness of a recording layer of an optical recording medium is adjusted to control the disc absorptivity, and the recording layer thickness is matched with a power difference between a laser write power (Pw) and a laser erase power (Pe), so as to control the optimal laser power for irradiating and accordingly changing the optical properties of the recording layer. It is found that by using properly increased recording layer thickness corresponding to a given disc absorptivity, and properly matching the recording layer thickness with a properly increased power difference, the read stability and recording characteristics of the optical recording media can be improved without significantly changing the layer structure and writing strategy of the optical recording medium.

  • Patent number: 7677388
    Abstract: A disk protecting plate includes a disk-shaped plate body having a central through hole. The plate body is provided on one side with a centered and low-raised annular wall, and a plurality of reinforcing ribs radially outward extended from the annular wall. Each of the reinforcing ribs has a top gradually inclined toward an outer circumferential periphery of the plate body. The disk protecting plate with the radially outward inclined reinforcing ribs may be made with reduced material to obtain a reinforced overall structural strength without forming an excessively thick outer periphery, and a plurality of disks concentrically stacked and packaged between two pieces of the disk protecting plates could therefore be effectively protected against damage caused by compression or impact against the disk protecting plate.
