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.

摘要： Methods and apparatus for interleaving data in a multitrack tape drive and for writing data on a multitrack tape in the tape drive. One method includes: partitioning the data into m(2n+k) data blocks, where each data block has a logical array of rows and columns of data bytes; error-correction coding a row and a column of the logical array to produce an encoded block; assigning the coded row to a respective location in a logical interleave array having L rows and 2n+k columns of locations; and writing a sequence of assigned coded rows simultaneously in respective data tracks on the multitrack tape. The coded row is assigned such that the minimum Euclidean distance on the multitrack tape between the coded rows is maximized. The apparatus includes units for performing the methods and the computer program product includes a program code means for causing a computer to perform the methods.
