摘要： A system includes a preamble determination module configured to determine an expected preamble of a target track. The expected preamble includes an associated timing recovery pattern. A filter module is configured to receive a readback signal read from the target track based on the expected preamble, and selectively filter the readback signal to remove inter track interference from the readback signal based on the expected preamble.

摘要： 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.

摘要： 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.

摘要： In a method for providing an estimate of a head position for a disk drive, a readback signal is filtered. The readback signal includes a first position signal component corresponding to a first position pattern on a disk, and includes a second position signal component corresponding to a second position pattern on the disk. Filtering the readback signal enhances a signal-to-noise ratio (SNR) of the readback signal with respect to the first position signal component and the second position signal component. An estimate of an amplitude of the first position signal component is generated based on the filtered readback signal, and an estimate of an amplitude of the second position signal component is generated based on the filtered readback signal. An estimate of a head position with respect to a track on the disk is generated based on the estimate of the amplitude of the first position signal component and the estimate of the amplitude of the second position signal component.

摘要： A decision-driven control loop wherein a first reconstructed signal is compared to an unreconstructed data symbol signal to initially drive the control loop. A second reconstructed signal that is based on a longer memory path than the first reconstructed signal is evaluated against the first reconstructed signal. The decision-driven control loop is ultimately controlled based on the results of the evaluation between the first and second reconstructed signals. The inventive decision-driven control loop, which may be implemented in software, may form part of a read channel in a storage device.

摘要： In a method for estimating a sequence of input data symbols of a CPFSK-modulated data signal transmitted via a faulty channel, in the course of an ACS operation for calculating a transition metric value, an estimated value is determined for the replacement symbol occurring during the linear approximation of the CPFSK. That estimated value is considered in calculating the transition metric value.
