    摘要: A disk drive data storage device and a method for implementing a sector selectable write-once read-many (WORM) functionality on the disk drive storage system are disclosed. Data stored in a sector on magnetic storage media or on rewritable optical media are protected from being overwritten by having additional (WORM) bits in the sector header to denote the protection status of the data in that sector. When data is to be written to a sector of a disk drive of the storage system, the sector header for that sector is read and the WORM bits are examined. If the value of the WORM bits indicates that the sector is protected, the write command will not be executed and an appropriate error condition is posted to the host system. If the WORM bits for the sector indicates no WORM protection, the data is written to the sector.

    摘要: Improved reliability for multi-layer media is providing by the present invention. A data stream U is received for recording to a multi-layer rotating storage medium, the data stream U comprising a sequence of data bits. Each data bit U(J) is encoded into X representation bits. A first representation bit B(1,J) is recorded onto a first layer of the storage media, the second representation bit B(2,J) is recorded onto a second layer of the storage media, etc. When a request to read the recorded data U from the storage media is subsequently received, a plurality of the X representation bits are read back from the storage media and are decoded into the original data bit U(J). In one embodiment, encoding may be performed with a convolution encoding algorithm and decoding with a PRML decoding algorithm. In another embodiment, Reed Solomon encoding/decoding may be employed.

    摘要: A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.
