A system and method are provided wherein digital data representing content and associated license rights may copied to a storage medium, such as a removable storage medium, whereby the serial number of the copied-to storage medium is integrated into the licensing scheme utilized to secure the digital content. As a result, the digital content is pre-authenticated and bound to the copied-to storage medium, obviating the need to access a network or other location for access to the protected content.

A disk is manufactured having a reduced capacity based on a quantity of addressable and non-addressable portions. The method of formatting the disk comprises identifying a first quantity of the storage portions; and labeling the first quantity of storage portions as non-addressable storage portions such that the non-addressable storage portions cannot be accessed by a user or a disk drive. The first quantity of storage portions may include addressable portions designated as non-addressable portions.

Data on a master is read into a master image file, and the master image file is manipulated to include a benchmark comprising tracking and verification information tied to at least a portion of the master image file. Thus, a copied-to storage media as copied from the master image file also includes such benchmark, a data alteration of the master image file causes a mis-match with regard to the benchmark in such master image file, and a data alteration of the copied-to storage media also causes a mis-match with regard to the benchmark in such storage media as copied from such master image file. The benchmark may include a part identifier and a security identifier.

A system and methods for providing offset information on a storage medium are provided by writing at least one unalterable mark on the storage medium during a manufacturing formatting process. The unalterable mark(s) are variably offset from a fixed position. The amount of offset represents a first source of unique information. The unalterable mark(s) themselves comprise a second source of information. Both sources of information are combinable and may be utilized in connection with the generation of a unique serial number for the storage medium or for other digital rights management purposes.

A defect map for a data-storage medium is generated without the use of a hard index on the medium. The servo sectors normally written to the medium during formatting operations are utilized to identify the angular positions of defective data sectors. The track-location data typically stored in each data sector is used to identify the radial positions of defective sectors. This positional information is processed by a set of computer-executable instructions that generate a graphical representation of the data-storage medium. Symbols are placed on the graphical representation in positions corresponding to the locations on the medium at which defective data sectors are identified.

Methods are provided for preventing data from being written to a data sector that has been identified as faulty on a disk in a disk drive system. It is first determined whether data of a data sector of a portion of a disk is recoverable. If the data is non-recoverable, an invalid logical ID is written to the logical block address (LBA) corresponding to the data sector thereby identifying the data sector as faulty and preventing data from being written at the data sector. The LBA is then reallocated to point to a different data sector if the data is non-recoverable. Thus, further data directed to the LBA will be written to the different data sector responsive to the reallocated LBA, thereby avoiding writing the new data to the data sector identified as faulty. Internal drive read re-tries can still take place on the faulty data sector even after the LBA has been assigned an invalid logical ID.

Method for preventing repeating non-recoverable read errors at same physical location on data storage media

A method and apparatus for detecting defects on a surface of a recording medium in a magnetic disk apparatus. An idling state of the magnetic disk apparatus is detected and a determination is made of the duration that the recording medium has been in use. The presence/absence of defects on the surface of the recording medium is then sequentially detected, responsive to the duration and the idling state, beginning at a start location of the recording medium. Data located at a detected defect is reallocated to a predetermined storage area, and the detected defect is mapped in a defect location map.
