摘要： A digital optical information disk contains content and/or non-content information on both sides of a single substrate produced by a process that embosses the surfaces of both sides substantially simultaneously. Simultaneous molding substantially eliminates the need for lamination when two or more data layers are to be provided. Preferably, the disk is relatively small, such as less than 50 mm in diameter and can replicate marks or features with a z-dimension magnitude of about 80 mm or more. The disk remains within a specified opto-mechanical range of an optical transducer and has little, if any, non-planarity (warp) or other distortion. The disk can be used for reading pre-written or mastered content, e.g., in a user's device, and/or can include information or features that permits or supports utility functions, allowing the user to record data thereon such as tracking, sector, location, timing, synchronization features or combinations thereof. Preferably, the disk is formed by an injection-only technique, although it is possible to provide suitable disks by an injection-compression technique as well.

摘要： Disclosed is an optical data storage medium with enhanced contrast. The optical data storage medium includes a substrate having oppositely facing first and second surfaces. A first metal/alloy layer is formed overlaying the first surface of the substrate. The first metal/alloy layer is formed from tin, antimony and element selected from the group consisting of indium, germanium, aluminum, and zinc. After the first metal/alloy layer is formed, a first dielectric layer is formed overlaying the first metal/alloy layer. This dielectric layer is formed from silicon oxynitride. The first metal/alloy layer is positioned between the substrate and the first dielectric layer.

摘要： An optical storage disc has portions for storing pre-recorded or mastered information and portions for storing user writable information, where the mastered portion and the writable portions have different storage capacities or areal data densities. During manufacture, a substrate is formed with a sequence of bumps to represent the mastered information and a series of grooves and lands, where information can later be written on the lands. A phase-change material is deposited over the substrate, the phase-change material changing both physical structure and optical constants when written to, e.g., by a laser.

摘要： A first surface optical disk is disclosed that has machine readable code information, such as bar code information, disposed thereon to permit a disk drive or other device to obtain certain basic information regarding the disk in an efficient and reliable manner. The machine readable code may include error detection and error correction code to correct errors, such as those caused by surface dust, that may arise during reading the machine readable code. The machine readable code may be disposed within a portion of a ring on the optical disk. Human readable alphanumeric characters, including graphics, identifying the side of the optical disk and other basic information may also be disposed within the ring.

摘要： Optical disks are formed using mother stampers having a spiral groove and/or a spiral pattern of pits corresponding to the pattern from an original laser cut. The mother stamper is the mirror image of the corresponding father stamper. Injection molding of polycarbonate material or other suitable material using the mother stamper forms an optical disk having lands and bumps corresponding to the original laser cut. A phase-change material having constructive change in phase and thickness is deposited over the polycarbonate material to create the disk. Data is written to and read from the lands, and tracking is performed on the wobbled lands.

摘要： A phase-difference sensor measures the spatially resolved difference in phase between orthogonally polarized reference and test wavefronts. The sensor is constructed as a linear-carrier phase-mask aligned to and imaged on a linear-carrier detector array. Each adjacent element of the phase-mask measures a predetermined relative phase shift between the orthogonally polarized reference and test beams. Thus, multiple phase-shifted interferograms can be synthesized at the same time by combining pixels with identical phase-shifts. The multiple phase-shifted interferograms can be combined to calculate standard parameters such as modulation index or average phase step. Any configuration of interferometer that produces orthogonally polarized reference and object beams may be combined with the phase-difference sensor of the invention to provide single-shot, simultaneous phase-shifting measurements.

摘要： An optical data storage/recording medium is provided with a thin film adjacent a data surface. Potential undesired effects of the presence or thickness of the thin film are adjusted for or compensated for to reduce or eliminate the undesired effects. In one aspect, the (uncoated) physical size of data layer features are adjusted so as to produce desired as-detected sizes, shapes or spacings, after a coating or thin film is present. In one aspect, length and/or width of raised features have an uncoated physical size less than the desired as-detected size. In one aspect, depressed features have uncoated physical dimensions greater than desired as-detected dimensions.
