  • Patent number: 8422160
    Abstract: A system includes an input circuit, an analog to digital converter, first and second harmonic sensor modules, a head height control module, and a weighting function module. The input circuit receives analog signals from a read/write head. The analog to digital converter generates digital samples in response to the analog signals. The first and second harmonic sensor modules determine, from the digital samples, a first magnitude of a first frequency component and a second magnitude of a second frequency component, respectively. The head height control module estimates a height of the head over a storage medium in response to a comparison of the first magnitude and the second magnitude, and selectively adjusts the height in response to the estimated height. The weighting function module applies a time domain window function to the digital samples to create modified samples on which the first and second harmonic sensor modules operate.

  • Patent number: 8405928
    Abstract: Methods, apparatuses, and systems implementing analog techniques to decode signals extracted from servo wedges of computer-readable storage media. A digital representation of at least a portion of a repeatable runout (RRO) signal derived from an analog signal read from a computer-readable storage medium is obtained. An estimate of a magnitude of the RRO signal is determined based on the digital representation. An error signal is generated to represent a difference between the estimate of the magnitude and a specified level of the magnitude of the RRO signal, and a gain value is configured, based on the error signal, for decoding a signal from the computer-readable storage medium.

  • Patent number: 8395858
    Abstract: Methods and apparatus are provided for performing interpolated timing recovery using a frequency and phase estimate. An analog signal representing a sector is asynchronously sampled and stored in a storage device. A retiming circuit reads the stored samples and, based on first portions of first and second timing portions of the sector, determines phase adjustments. The retiming circuit generates a signal representing the samples at the adjusted phase and determines sample shift adjustments based on the generated signal and second portions of the first and second timing portions. The retiming circuit computes start and end indices of the sector in the buffer based on the sample shift adjustment and phase adjustment. The start and end indices may be used to compute a frequency estimate. The frequency estimate and a phase adjustment is used to interpolate the asynchronous samples at the appropriate frequency and phase.

    Abstract: A system for identifying and compensating for non-linear transition shift in a magnetic medium data storage device is disclosed. The non-linear transition shift compensation system includes a non-linear transition shift estimation module adapted to generate non-linear transition shift estimates for specific bit patterns. The system further includes a pre-compensation module adapted to adjust the temporal spacing of binary transitions written to the magnetic medium based on the non-linear transition shift estimates generated by the non-linear transition shift estimation module for specific bit patterns corresponding to bit patterns appearing in the data being written to the magnetic medium.

  • Patent number: 8339722
    Abstract: Systems, methods and computer program products for estimating a position of a head in relation to a storage medium are described. A read channel can be used to receive a readback signal containing servo information obtained from a storage medium, and to demodulate the received servo information including position error signals to deduce a position of a read/write head in relation to the storage medium. The read channel can demodulate the received servo information to obtain amplitude and/or phase information. In some implementations, digital sampled values can be generated based on the readback signal, and the digital sampled values can be integrated using an integrator to obtain accurate and reliable amplitude and phase information that are used to determine the position of the read/write head.

  • Patent number: 8339720
    Abstract: Methods, systems and computer program products for performing hybrid defect detection are disclosed. A hybrid defect detection mechanism may be used to detect various classes of defects (e.g., long and shallow defects, and short and deep defects) while reducing the probability of a miss or false alarm. In some implementations, the hybrid defect detection mechanism may utilize defect detectors to each receive signal samples and apply a different set of parameters indicating a different respective window to the signal samples. Each defect detector may generate a corresponding output based on a count of signal samples within the corresponding window that are associated with abnormal signal quality.

  • Publication number: 20120308629
    Abstract: According to an aspect of the invention, injectable bulking compositions are provided which contain the following: (a) fibers that are configured to prevent migration to locations in the body remote from the injection site, for example, because they have a minimum length that is sufficiently large to prevent migration of the fibers and/or because they have surface features that stimulate host tissue response to lock the fibers in position and (b) a carrier in an amount effective to render the composition injectable.

  • Patent number: 8279546
    Abstract: Systems and methods for detecting and designing enhanced disk sync marks using correlation detection are disclosed. The enhanced sync marks provide better noise immunity and higher detection rates over traditional Viterbi-based detection schemes even with a shorter sync mark length. The disk sync mark may provide optimal noise immunity for a particular target polynomial or a plurality of common target polynomials. The minimum Euclidean distance between a candidate sync mark and a plurality of right-shifted versions of the candidate sync mark is computed and compared with other candidate sync marks. The sync mark with the largest minimum Euclidean distance is then selected as the optimal mark. Systems and methods are also disclosed for detecting and designing a disk sync mark using correlation detection when the polarity of the disk is unknown or time-varying.

  • Patent number: 8261172
    Abstract: Apparatus and methods are disclosed for decoding data stored on a data storage medium. A disclosed decoding method and decoder include a radial incoherence (RI) detector that increases the probability of detecting RI and improves the decoding performance in terms of the bit error rate of the decoded signal. RI is detected by comparing an input signal to the decoder against a RI threshold value and generating a RI-type signal. The RI detector may include a filter for filtering out noise and error in the RI-type signal, an adaptive threshold unit that adjusts the RI threshold value based upon the RI-type signal, a transition-based threshold unit that adjusts the RI threshold value based upon each transition in the input signal, or a path-based threshold unit that adjusts the RI threshold value based upon a best surviving path corresponding to the input signal, in combination or alone.
