摘要： In one embodiment, holographic data storage medium includes a first thermoplastic substrate portion having a thickness less than approximately 2 millimeters and a second thermoplastic substrate portion having a thickness less than approximately 2 millimeters. A holographic recording material may be sandwiched between the first and second thermoplastic substrate portions. By making thermoplastic substrate portions sufficiently thin, edge wedge problems can be avoided.

摘要： A disc molding apparatus for forming an optical disc. The apparatus has a disc substrate cavity and a sprue mechanism in fluid communication with the cavity. A removable stamper located on one side of the disc substrate cavity forms data onto the disc substrate and the stamper is relasibly locked within the apparatus by an inner holder, which includes a locking mechanism. The apparatus also has a mechanism that forms a disc alignment mechanism in the disc substrate wherein the disc alignment mechanism is between the formatted data and a center of the disc substrate and the concentricity of the formatted data is specified relative to the disc alignment mechanism.

摘要： A rewritable optical recording disk has an increased thickness that is greater than or equal to approximately 1.5 mm. In particular, the disk may have a substrate with a thickness that is greater than or equal to approximately 2.3 mm and less than or equal to approximately 2.6 mm. The increased thickness of the substrate enhances the flatness of the recording disk relative to a recording plane. In particular, the increased thickness reduces process-induced surface variations such as warpage and tilt, and provides the disk with increased stiffness to resist deflection during use. The enhanced flatness enables data to be recorded on the disk in a consistent manner with greater spatial densities using techniques such as near-field, air-incident recording. The resulting disk thereby yields greater spatial density and data storage capacity.

摘要： A rewritable optical recording disk has a substrate with an increased thickness that is greater than or equal to approximately 1.5 mm and less than or equal to approximately 2.5 mm. The increased thickness of the substrate enhances the flatness of the recording disk relative to a recording plane. In particular, the increased thickness reduces process-induced surface variations such as warpage and tilt, and provides the disk with increased stiffness to resist deflection during use. The enhanced flatness enables data to be recorded on the disk in a consistent manner with greater spatial densities using techniques such as near-field, air-incident recording. The resulting disk thereby yields greater spatial density and data storage capacity.
