摘要： An apparatus, system, and method are disclosed for adaptive asynchronous equalization using leakage. An equalizer sums products of a plurality of tap signals from a delay line sampling a read signal and a plurality of corresponding tap coefficients to form an equalized signal in an asynchronous time domain having a first sampling rate. A leaky function module calculates a leaky function for each tap coefficient in the asynchronous time domain. An adaptation module adapts each of the tap coefficients as the leaky function for each tap coefficient summed with a signal-dependent updating function for each tap coefficient.

摘要： Method, apparatus and computer program product adjust gain in a read channel of a magnetic media data storage device. A digital signal sample having a data-dependent noise component is received. A gain value, stored in a location in a gain table, is selected in a data-dependent manner. The gain of the signal sample is adjusted in response to the selected gain value. A bit pattern is detected from the gain-adjusted signal sample and a data output signal is output based upon the detected bit pattern.

摘要： Method and computer program product are provided to encode data for recording onto media whereby modulation and linear constraints from a concatenated code or product code are imposed. A first array of unencoded user data is generated. Each row is modulation encoded to enforce a first modulation constraint; the array is transformed into a second array which is transformed into a third array having predetermined empty locations in each column interleaved with the modulated data. A C2-parity byte is computed for at least some of the empty locations of the third array and a fourth array is generated. C1-parity symbols in each row are computed, generating a fifth array. A second modulation constraint is enforced on each C1-parity symbol in each row of the fifth array, generating a sixth array. The rows of the sixth array are assembled with header and sync fields for recording onto a recording media.

摘要： A dibit response estimation generator receives a DSS sequence and a DSS readback sequence, which is a function of a channel processing of the DSS sequence by a read channel. The generator generates a cyclic dibit response vector as a function of the DSS sequence and the DSS readback sequence. The generator further generates an error signal as a function of a comparison of the DSS readback sequence and a filtering of the DSS sequence based on the cyclic dibit response vector. An unacceptable error signal indicates a need to adjust the cyclic dibit response vector to yield an acceptable comparison of the DSS readback sequence and the filtering of the DSS sequence based on the cyclic dibit response vector.
