  • Configuration of channel-to-controller interface in a disc drive
    Patent number: 6594096
    Abstract: Embodiments of the present invention illustrate various configurations of a channel-to-controller interface. In one embodiment, width of symbols crossing the interface is fixed, as is the clock rate. In other embodiments, the symbol width is variable, and the clock rate is also varied based upon the size of the interface symbol width and the operation of the channel.

  • Physical block address recovery apparatus system and method for cyclic error correction codes
    Patent number: 6574774
    Abstract: The invention relates to apparatus and method that provide an improved media codeword and which can distinguish an uncorrectable data error from a wrong block address error and permit the address to be recovered from readback data. In accordance with one embodiment of the invention, method for generating parity is provided in which a sequences representing address and data are received. The address sequence is multiplied by a set of multiplier symbols to generate a first sequence of product symbols. A first portion is added to the data sequence prior to generating a first parity sequence and second portion is added directly to the first parity sequence to generate the final parity sequence. A corresponding method of generating syndromes from readback data is provided. System and apparatus incorporating the inventive method are also provided.
