Abstract: 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 nm 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.

Abstract: An optical medium including a substrate and information content portions is provided. The optical medium is preferably a first-surface medium in which a read light beam during a read operation impinges first on the information content portions of the medium before it impinges on the substrate. The information content portions can include both read-only and writeable areas. The information content portions containing both read-only and writeable areas can be made from the same material or composition. The optical medium diameter is no greater than about 40 mm. The thickness of the optical medium is no greater than about .6 mm. When joining a hub assembly to the medium, a portion of the medium, such as a track, is utilized for alignment purposes. The ratio of the total height of the hub assembly to the thickness of the optical storage medium is at least about 1.5. The hub assembly can include a magnetic coupling for use in connecting the optical medium to an optical drive spindle.

Abstract: 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.
