Abstract: Aspects of the invention include a method and apparatus to transfer data from a peripheral device directly to a disc drive storage system. In one aspect, the disc drive uses a transfer protocol that determines the types, sizes and data location structure for each file. In another aspect, the disc drive includes a file allocation table that stores the file location for the peripheral devices on the disc drive to increase the file transfer efficiency and speed.

Abstract: The present invention includes a method and apparatus to copy protect data written and read on a disc drive system using a drive defect list.

Abstract: The present invention includes a method and apparatus to write and read copy protected data on a disc drive storage system by encoding and decoding data to be copy protected using servo wedge data as the encoding element. In one aspect, the drive is marked by a number generated from the servo wedge data.

Abstract: Method and apparatus for storing and retrieving copy-protected data within storage devices such as, for example, disc drives. Data that is to be copy protected is written on the storage device. A first data list, such as a manufacturer's storage device defect list, is copied and used to make a second data list. Then, the first data list is modified such that the area where the copy protected data is stored is identified as defective. Unless a request to read the copy protected data is received, the first data list is used and the copy protected data area is considered defective. However, if a request to read the copy protected data is received, the second data list is used and the copy protected data is read from its storage location.

Abstract: The present invention includes a method and apparatus to write and read copy protected data on a disc drive storage system using a servo wedge.

Abstract: Aspects of the invention include a method and apparatus to defragment data on a disc drive storage system by optimizing the available physical block address on a media into one or more contiguous physical block addresses then storing the fragmented data into the one or more contiguous block address. In one aspect, the disc drive uses a reserved area on the media to hold fragmented files during the defragmentation process. In another aspect, sectors of the media having faster access time are used to store defragmented files that have a higher incidence of access relative to other files on the media.

Abstract: Aspects of the invention include a method and apparatus to optimize the location of data on a disc drive storage system by optimizing the physical location of the file to allow the read ahead memory cache to operate more efficiently. In one aspect, the disc drive uses a reserved area on the media to hold files during the optimization process. In another aspect, the drive includes an optimization table that stores optimized file access data to further enhance the drive performance.

Abstract: An apparatus and method for efficient defect management in a magneto-optical data storage system store a map of current and predicted defective physical addresses of a recording disk, and then skips defective data wedges to more completely utilize the non-defective recording surface area available for a given track. The invention also stores groups of physical addresses that share defects to decrease the number of entries in the map of defective physical addresses, and also to increase the effective defect management capacity of existing hardware and software.

Abstract: Aspects of the invention include a method and apparatus to transfer specific data files from a disc drive storage system to an output device such as a printer. In one aspect, the disc drive uses a transfer protocol that determines the files stored from a peripheral device and sent to the output device. In another aspect, the transfer program compares the files sent to the output device to a file structure stored on the disc drive and presents the unsent files to the output device for processing.
