摘要： Protected content is distributed to users without the need for payment at the time of media distribution. Payment can be performed at a later time in response to which content may be enabled, and/or users may selectively pay for, and receive enablement of, content such that only portions of content may be accessible at a given time. Following the first enablement of content, access rights may be expanded or otherwise changed, e.g., in response to a second payment.

摘要： An optical medium (112) uses a single structure or format (such as identical materials, layers and the like) for both a region for holding information content-mastered data and a writeable area (118, 126, 128). In one aspect, a writeable region (118, 128) of a medium (112) with information content-mastered data is used in connection with paying, collecting or accounting for usage or royalties for proprietary intellectual property embodied in or associated with the content. In one embodiment, a key permitting access to some or all of the content, preferably when combined with a disk serial number, is stored in the writeable area (118, 128), which is preferably user-inaccessible.

摘要： A user-removable optical data storage system is provided. A rotatable first-surface medium (114) is enveloped in a cartridge (124, 126). The cartridge provides relatively large data capacity such as about 0.25 Gbytes or more despite a relatively small size such as about 35 mm X 35 mm X 3 mm. Preferably the cartridge substantially seals the data surfaces of the medium when the cartridge is withdrawn from a drive and at least a portion of a surface is automatically exposed to the objective of an optics arm when the cartridge is inserted in the drive. Tracking involves rotating an optic arm (236) about an axis parallel to the disk rotation axis (237). Focus can involve pivoting the arm about an axis parallel to the disk surface.

Payment can be performed at a later time in response to which content may be enabled (118), and/or users may selectively pay for, and receive enablement of, content such that only portions of content on given media may be accessible at a given time. Following the first enablement of content, access rights may be expanded or otherwise changed, e.g., in response to a second payment.

摘要： A method and system for managing a plurality of defects that may cause an error during a write operation in a write-once data storage disk is provided. A host system sends a write command to a disk drive that contains the storage disk. The process detects any errors that may occur during the write operation. When an error is detected, a 'skip list' containing the addresses of physical sectors on the disk that are to be skipped during a read operation is updated, the write operation is suspended, and the process attempts to rewrite the data in another sector. If the rewrite is performed successfully, the write operation continues. Otherwise, the write operation is terminated and the host device is notified. While the disk drive is operative, the skip list is preferably maintained in a buffer memory, but periodically the entries in the skip list are copied to the disk for permanent storage. Before a read operation begins, the skip list is copied from the disk to the memory. When a file is read from the disk, any 'skip sectors' that are encompassed within the file are skipped (i.e., the data in those sectors is not read). The method of this invention is particularly useful in supplementing an error correction code, which typically has difficulty dealing with errors of longer duration.

摘要： An optical medium (112) uses a single structure or format for both master data (126) and writeable area (128). In one aspect, writeable area (128) is used in connection with paying, collecting or accounting for usage or royalties for proprietary intellectual property embodied in or associated with the content. In another aspect, writeable area can be used for storing later-written information (228) such as annotations, highlighting, reordering, remixing, modifications, supplements, collections, additions, bookmarks, cross references, hypertext or hyperlinks and the like, annotations and similar materials can be associated by the user with particular portions or content of the mastered data (126).

摘要： The present invention relates to an optical disk drive comprising an actuator assembly (10) having a first portion (412) and a second portion (414) being pivotally mounted to a shaft for positioning the second end relative to the surface of the disk, the second portion comprising a plurality of a planar elements, and an optical pick up unit acting focus a light beam on an optical disk. The second portion may comprise at least three planar elements, and may include fibres selected from the group comprising carbon, magnesium, borom, berryllium, Kevlar, glass and ceramic. This ensures a high stiffness tiweight ratio.
