摘要： One embodiment disclosed is method for protecting data stored on at least one storage unit against uncorrectable media errors. The method includes associating a given redundancy set of at least one redundancy information sector (R) with a given data set of at least two data information sectors (D). The information content of the redundancy set is computed dependent on the information content of the data set. A storing operation stores the information content of the redundancy set consecutively with the information content of the data set forming a segment such that the redundancy set is placed logically in between a first part and a second part of the data set, and accessing at least one data information sector (D) in the data set by reading and/or writing the information content of the at least one data information sector (D) and at least one redundancy information sector (R) in the redundancy set with a single request.

摘要： Methods and apparatus are provided for controlling writing and reading of data in an array of A storage fields of a probe-based data storage device in which data is written to and read from the array of storage fields by a corresponding array of probes. One method provides error-tolerance by exploiting the inherent parallelism of the probe storage array. A user data block to be written to the A-field array is first coded to produce a plurality of C-byte codewords, such that r.C=k1A where r is the number of codewords and k1 is an integer greater than or equal to 1. A sub-blocks of k1 bytes are produced from the codewords by selecting successive bytes of each sub-block cyclically from the r codewords. The A sub-blocks are then written via respective probes to the corresponding storage fields of the storage field array.

摘要： A method and apparatus for providing a read channel having combined parity and non-parity post processing is disclosed. A post-processor combines parity and non-parity post processing to make both parity and non-parity corrections so that error events that cannot be detected by parity may be corrected. Non-parity detectable error events are only kept for consideration if their likelihood is above a set threshold.

摘要： A data storage system includes an encoder subsystem comprising an error correction code encoder, a modulation encoder, and a precoder, and a decoder subsystem similarly comprising a detector, an inverse precoder, a channel decoder, and an error correction code decoder. The error correction encoder applies an error correction code to the incoming user bit stream, and the modulation encoder applies so-called modulation or constrained coding to the error correction coded bit stream. The precoder applies so-called precoding to the modulation encoded bit stream. However, this precoding is applied to selected portions of the bit stream only. There can also be a permutation step where the bit sequence is permuted after the modulation encoder before precoding is applied by the precoder. The decoder subsystem operates in the inverse manner.

摘要： An apparatus for providing data dependent detection in a data read channel is disclosed. Parameters in a read channel are dynamically adjusted according to data dependent noise. For example, a comparison in an add-compare-select (ACS) unit of a Viterbi decoder may be adjusted or offset terms in error event filters may be biased to choose a Viterbi sequence with more transitions or to compensate for polarity dependent noise.

摘要： Method and apparatus for decoding data in a data storage system. In operation, a detector generates an output bit stream in dependence on a data block received from a storage subsystem of the data storage system. A post processor connected to the detector generates a first error corrected bit stream in dependence on the output bit stream and the data block. An error correction decoder connected to the post processor generates a second error corrected bit stream in dependence on the first error corrected bit stream and also generates a checksum in dependence of the second error corrected bit stream. A feedback path supplies from the error correction decoder to the post processor pinning data indicative of locations of correct bits in the second error corrected bit stream in the event that the checksum is indicative of errors in the second error corrected bit stream and the second error corrected bit stream comprises at least one correct interleave. The post processor regenerates the first error corrected bit stream in dependence on the pinning data received from the error correction decoder.
