Abstract: A dual sided optical storage medium which comprises a substrate disk having a first information layer readable from one side of the medium through the substrate disk and one or more information layers formed on the non-read side of the first information layer and configured to be read from the other side of the medium.

Abstract: An optical recording medium includes a first half-disc and a second half-disc. The first half-disc includes a substrate and an information layer (including a reflective layer) formed on a first side of the substrate. The second half-disc is bonded by an adhesive to a second side of the substrate of the first half-disc. In addition, a cover layer is formed over the first reflective layer. The cover layer has a thickness of approximately 0.1 mm. The substrate of the first half-disc has a thickness in a range of 0.3 mm to 1.0 mm. The first and second half-discs together have a combined thickness in a range of 0.8 mm to 1.3 mm.

Abstract: An optical recording medium includes a recording layer in or on a substrate, a light-transmitting cover layer over said recording layer, and a disc rib over an outer periphery of a first side of the substrate and delimiting an outer diameter of the cover layer.

Abstract: A method of making composite discs continuously, including forming for each disc a first, a second layer, and a third support layer, each support layer being disc shaped and having a first surface with information indicia. An information layer is added to each support layers respectively. The said first and third support layers are positioned in a facing relationship, with the first and third information layers being adjacent. The third support layer is then separated from the third information layer, which thus remains attached to the first support layer. The first and second support layers are then joined. These steps are performed on a manufacturing line with conveyor belts transferring the support layers from station to station.

Abstract: A method for manufacturing an optical recording medium includes forming a light-transmitting cover layer over an information layer by depositing a predetermined volume of a liquid resin on the information layer. The method may further include forming a disc rib over an outer periphery of the information bearing side of the substrate, to stop flow of the deposited resin beyond the outer disc periphery. An optical recording medium formed through such a method includes a disc rib delimiting an outer diameter of the light-transmitting cover layer.

Abstract: Methods for forming a single-side-readable DVD having graphical information viewable from the DVD's frontside disc are provided. A first, frontside disc having a first and a second surface, with the second surface comprising program information and coated with a semi-reflective coating, is bonded to a second, backside disc having a third and a fourth surface. A first portion of the fourth surface comprises spillover program information and a second portion of the fourth surface comprises graphical information. The fourth surface is coated with a reflective coating. During DVD formation, the frontside and backside discs are adhesively bonded back to back so that the second surface of the frontside disc faces the fourth surface of the backside disc. Because the frontside disc comprises a semi-reflective coating, the graphical information on the second portion of the fourth surface of the backside disc is viewable through the frontside disc.

Abstract: A system and method are provided that allow an optical media inspection device to detect defects on or in optical media despite the presence of gross deformations in the media that would otherwise interfere with the inspection process. A holding device holds the optical media near the center while it is rotated for inspection. A negative displacement prohibitor impedes any negative displacement of the optical media. A positive displacement inhibitor, i.e., air pressure exerted on the optical media, holds the optical media substantially flat while it is being inspected. A closed-loop feedback system may be used to control the amount of air pressure exerted against the optical media.

Abstract: A dual-layer DVD disc that does not require a stamping step (typically, as part of the 2P prior art manufacturing process) during its manufacture. A polycarbonate substrate is molded and coated with a semireflective data layer in the usual way. A PMMA substrate is molded and coated with a fully reflective data layer. Adhesive is placed on the semireflective data layer, and the fully reflective data layer is transferred from its PMMA substrate to the polycarbonate substrate. The polycarbonate substrate thus ends up with two data layers in conformance with the DVD specifications, and the PMMA substrate can even be recycled for another use.

Abstract: Methods and apparatus for making optical discs (e.g., for use in digital versatile discs ("DVDs") are provided. An optical disc made in accordance with this invention includes at least one roughened surface portion to mask any manufacturing irregularities and thereby improve the appearance of the disc and, if the disc is used in a DVD, then also the DVD. The method includes roughening a section of a mold in contact with molten plastic, molding an optical disc with that mold so that at least one side of the optical disc has a roughened surface portion, and if the disc is used in a DVD, securing the disc to another disc with adhesive to form a DVD.
