摘要： A read channel equalizer of a magnetic tape drive which equalized digitally sampled magnetic signals detected by a read head is dynamically adapted. A detector of equalizer dynamic adaptation logic compares equalizer output signals to desired values that are based on the decoding scheme (such as +2, 0 and −2 for PR4) to sense equalizer output signals that are offset from at least one desired value, and signals the fact of each offset and it polarity as amplitude independent error signals. The signaled sensed amplitude independent error signals are fed back to adjustable taps of the equalizer. The simplified error signals thus avoid complex calculations of waveform errors, such as least mean square calculations. The error signals may be weighted and may be adjusted to align synchronously provided error signals with asynchronous taps of the equalizer.

摘要： Methods and apparatus are provided for overwriting data in a probe-based data storage device in which data bits are represented by the presence and absence of pits at bit positions on a storage surface, the pits being formed in the storage surface by a probe mechanism of the device. Input data is coded to generate a coded bit sequence and an overwrite technique is employed to record the coded bit sequence on the storage surface over an old, previously-recorded bit sequence. Together with the properties of the coded bit sequence, the overwrite technique exploits the physical mechanism of the write process in that, with appropriate spacing of the bit positions on the storage surface, writing a pit at a bit position can erase an existing pit within a defined number of neighboring bit positions. In addition, the overwrite technique involves reading at least certain bits of the old bit sequence, whereby the pattern of data written on the storage surface in an overwrite operation is determined in part by the results of reading old data.
摘要翻译：提供了用于覆盖基于探针的数据存储装置中的数据的方法和装置，其中数据位由存储表面上的位位置处的凹坑的存在和不存在表示，凹坑通过探针机构形成在存储表面中装置。输入数据被编码以产生编码比特序列，并且采用重写技术来通过旧的先前记录的比特序列将编码的比特序列记录在存储表面上。与编码比特序列的属性一起，覆盖技术利用了写入过程的物理机制，因为在存储表面上的位位置的适当间隔中，在位位置写入凹坑可以擦除在定义的相邻位位置数。此外，覆盖技术涉及读取旧位序列的至少某些位，由此在重写操作中写入存储表面的数据模式部分地由读取旧数据的结果确定。

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： A method for operating plurality of DSL modem transmitters integrated within a circuit card. The method includes each DSL modem transmitter: generating a full power physical frame when the DSL modem transmitter is provided with data to transmit; generating a low power physical frame having a control channel signal component and no data; and selecting between the full power physical frame and the low power physical frame for transmission from the DSL modem transmitter, wherein selection of the low power physical frame for transmission from the DSL modem transmitter is based only on the DSL modem transmitter having no data to transmit. The method further includes limiting aggregate flow of data to the plurality of DSL modem transmitters such that a total power required by the plurality of DSL modem transmitters is held below a predefined target power level.

摘要： Provided is an asynchronous read channel shaped toward generalized partial response characteristics. The read channel is incorporated in a storage device to process signals read from a storage medium. An equalizer receives asynchronous input read signals and shapes the input read signals toward a desired fixed characteristic in an asynchronous time domain. An interpolator transforms the read signal from the equalizer in the asynchronous time domain to a synchronous time domain. A noise whitening filter processes the read signal shaped toward the desired fixed characteristic to produce an output read signal shaped towards a generalized partial response polynomial. A detector receives the read signal shaped towards the generalized partial response polynomial in the synchronous time domain to determine an output value comprising data represented by the input read signals.
