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： Trellis-enhanced precoding for trellis-coded transmission over channels with intersymbol interference allows coding and shaping gains to be achieved with minimal transmit power penalty for arbitrary signal constellations, provided the intersymbol interference channels are linearly invertible. This technique can be employed for trellis-coded transmission over a variety of communication channels. However, if the channel response exhibits spectral nulls, trellis-enhanced precoding cannot be applied because the corresponding inverse precoding operation at the receiver requires inverse channel filtering. For channels with a spectral null, this inverse operation can result in unlimited error propagation. The present invention allows trellis-coded transmission over channels exhibiting spectral nulls without incurring unlimited error propagation in the receiver. Coding gains are achieved with minimal transmit power penalty, like in the case of trellis-enhanced preceding. The invention is applicable for most signal sets used in practice.
摘要翻译：网格增强预编码用于具有符号间干扰的信道的网格编码传输允许以任意信号星座的最小发射功率损失来实现编码和整形增益，只要符号间干扰信道是线性可逆的。这种技术可用于各种通信信道上的网格编码传输。然而，如果信道响应呈现频谱零点，则不能应用网格增强预编码，因为接收机处的对应的反向预编码操作需要反向信道滤波。对于具有频谱零点的频道，该反向运算可能导致无限的误差传播。本发明允许在显示频谱零点的信道上进行网格编码的传输，而不会在接收机中产生无限的误差传播。编码增益以最小的传输功率损失来实现，就像在网格增强的情况下一样。本发明适用于实际使用的大多数信号组。

摘要： Methods and apparatus for compensating offsets in a read signal generated by a sensor associated with a probe of a local-probe data storage device during read-scanning by the probe of bit-positions on a storage surface. An apparatus comprises a generator for generating an offset compensation signal, and a subtraction stage for producing an output signal dependent on the difference between the offset compensation signal and the sensor read signal at each bit-position. In some embodiments, an offset signal generator generates an offset compensation signal dependent upon a predetermined measurement of the sensor read signal. In another aspect the offset signal generator low-pass filters the sensor read signal during read scanning to generate the offset compensation signal. Particular embodiments also include a secondary offset compensation stage for applying additional offset compensation techniques to the output signal from the subtraction stage.
