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 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.

摘要： A mold assembly for forming a replica disk in a disk molding process. The replica disk includes a formatted surface on both sides. The mold assembly includes a disk substrate cavity defined by a first block (26) having a first major surface, a second block (28) having a second major surface, and an outside edge. The first stamper (40) has an outside edge. The first outer holder (62) includes a first holder edge, the first holder edge extends over the outside edge of the first stamper, coupling the first stamper to the first major surface. A second stamper (42) having an outside edge is coupled to the second major surface. A channel is provided in fluid communication with the disk substrate cavity for allowing disk molding material to enter the disk substrate cavity. Further, a stripper mechanism (66) may be located at the outside edge, wherein the stripper mechanism is moveable relative to the first block and the second block.
