    摘要: Compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium, such as optical disc drives that may suffer damage if certain actions are performed on the optical medium. For instance, a compatibility engine of the optical disc drive applies compatibility information read from an optical medium to determine restrictions to impose on the use of the optical medium, such as restricting the optical disc drive from writing to the optical medium, reading from the optical medium or performing any operations until an update to the optical disc drive firmware is performed either automatically or by display of a compatibility user interface at an information handling system associated with the optical disc drive. In one embodiment, the compatibility information identifies incompatible optical disc drives and firmware versions by unique identifiers.

    摘要: Expiration information stored on an optical medium is applied to determine an expiration date of the optical medium that provides a predetermined reliability of information archived on the optical medium, such as a predetermined acceptable defect level of the information at the expiration date. An expiration engine associated with an information handling system or optical disc drive determines the expiration date from one or more factors, such as the manufacture date of read-only optical media, the initialization date of recordable optical media, a quality rating associated with a defect growth rate over time of the optical media, and a desired reliability. In one embodiment, the expiration engine writes expiration information to the optical media, such as a date stamp at initialization of a recordable optical medium. Alternatively, an expiration date is stored on an information handling system to provide expiration warnings a predetermined time before the expiration date.

    摘要: An optical disk system comprises a computer-readable medium containing code for controlling writing by the disk system to a removable optical disk. The optical disk system further comprises an optical pickup unit for reading data from the optical disk and writing data to the optical disk, a spindle motor for rotating the optical disk during the reading and writing, an optical disk controller that processes the data read from and written to the disk; and a processor that executes the code, thereby causing the optical disk system to write user data to the removable optical disk and to write an identifying value indicative of the optical disk system to at least one predetermined area of the removable optical disk.

    摘要: Data units on a data storage medium include a control field. In one example embodiment, a control block specifies the control action determined by the state of one or more bits in the control field. By using a control block to specify the action of one or more bits in the control field, the action controlled by the data in the control field can be changed to accommodate future needs.
