Abstract: A recording layer is described that is at least partially or entirely positioned at a distance T7 of less than 0.4 mm with respect to the second surface. When the optical recording medium is clamped in a drive, the recording layer has a “higher” position than a recording layer of a known DVD. The layer structure of the described optical recording medium reduces the thickness of the disc in an area of the recording layer. In particular, a thickness T1 of only 0.4 to 0.7 mm is possible while maintaining the reliability of the optical recording medium (i.e. without reading problems in most or all drives). Further, the optical recording medium may have only one substrate, i.e. only one disc of polycarbonate, whereas the other side of the recording layer is only covered by a protective lacquer.

Abstract: The recording layer of a DVD is at least partially or entirely positioned at a distance T7 of less than 0.4 mm with respect to the second surface. Therefore, when the optical recording medium of the present invention is clamped in a drive, the recording layer has a “higher” position. The layer structure of the optical recording medium is a feature in reducing the thickness of the disc in an area of the recording layer. In particular, a thickness T1 of only 0.4 to 0.7 mm is possible while remaining the reliability of the optical recording medium (i.e. without reading problems in most or all drives). Further, it is achieved that the optical recording medium may have only one substrate, e.g., one disc of polycarbonate, whereas the other side of the recording layer is covered by a protective lacquer.

Abstract: An optical recording medium is described. The optical recording medium includes a substrate and a recording layer arranged on one side of the substrate. The optical recording medium has a predetermined clamping area. The clamping area is formed such as to achieve a deformation of or a tension in at least a part of the optical recording medium when it is clamped within a recording and/or reproducing device.

Abstract: An optical recording medium is described. The optical recording medium includes a substrate and a recording layer arranged on one side of the substrate. The optical recording medium also includes a clamping area formed to achieve, when the clamping area is clamped by a device, a tension that enhances shape stability of at least a part of the optical recording medium outside of the clamping area.
