20080206508 | Method for producing optical storage media having multiple information layers - The present invention relates to a method for producing a two- or multilayer optical storage medium, wherein a first half-substrate with a first information layer is produced and a first metal layer is applied to the surface of the first half-substrate containing the information structure. Furthermore, a second half-substrate with a second information structure is produced and a separation layer is applied onto the surface of the second half-substrate containing the information structure. The two half-substrates are glued together by means of an adhesive, wherein the metal layer of the first half-substrate and the separation layer of the second half-substrate face each other with an adhesive layer in-between. After curing of the adhesive, the separation layer of the second half-substrate is separated from the adhesive layer and a second metal layer is applied onto the adhesive layer. | 08-28-2008 |

20090075016 | MULTILAYER INFORMATION RECORDING MEDIUM AND PRODUCTION METHOD THEREFOR - Disclosed herein is a method for producing a multilayer information recording medium having at least two information recording layers, in which a resin layer is formed between each pair of the information recording layers, the method including: holding a substrate; feeding a resin onto the substrate; and removing the excess resin by moving a squeegee throughout the entire surface of the substrate so that the interval between the bottom surface of the squeegee and the surface of the substrate is kept constant. The substrate may have a resin-coated region, onto which the resin is to be applied, and a non-resin-coated region, onto which the resin is not to be applied. In this case, the resin-coated region has a smaller contact angle with the resin than the non-resin-coated region. The method for producing a multilayer information recording medium may further include, prior to feeding a resin onto the substrate, subjecting a specified area of the substrate to an oil repellent treatment to increase the contact angle of the specified area with the resin. | 03-19-2009 |

20110200780 | OPTICAL INFORMATION RECORDING MEDIUM AND METHOD OF MANUFACTURING THE SAME - Provided is a manufacturing method of an optical information storage medium irradiated with laser beams to optically record or reproduce information. A method of manufacturing an optical information storage medium according to the present invention includes forming asperity patterns for guiding laser beams on both sides of a second substrate | 08-18-2011 |
20130302553 | OPTICAL MEDIA HAVING GRAPHENE WEAR PROTECTION LAYERS - An optical storage medium is disclosed that includes an optical disc having layers of graphene on one or both sides of the disc to provide wear protection against scratches and mechanical abrasion. Grahpene is a hard material that is 97.7% optically transparent. Thus, layers of graphene at or near the exterior sides of an optical disc provide wear protection to the optical media from mechanical abrasion and scratches while allowing laser light to pass through the graphene layers to read or write to the optical media. | 11-14-2013 |
20140050877 | OPTICAL INFORMATION RECORDING MEDIUM AND OPTICAL INFORMATION RECORDING MEDIUM LAMINATE - There is provided an optical information recording medium including a plurality of laminated resin layers, and an inorganic layer that is formed in an interface between the resin layers. Storage elastic moduli are different when the interface is assumed to be a boundary. An information signal is recorded in the interface. | 02-20-2014 |
