    摘要： One embodiment disclosed is method for protecting data stored on at least one storage unit against uncorrectable media errors. The method includes associating a given redundancy set of at least one redundancy information sector (R) with a given data set of at least two data information sectors (D). The information content of the redundancy set is computed dependent on the information content of the data set. A storing operation stores the information content of the redundancy set consecutively with the information content of the data set forming a segment such that the redundancy set is placed logically in between a first part and a second part of the data set, and accessing at least one data information sector (D) in the data set by reading and/or writing the information content of the at least one data information sector (D) and at least one redundancy information sector (R) in the redundancy set with a single request.

    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 uses the concept of sub-arrays to provide variable-rate read/write operation. Input data blocks are received for writing to the A-field array, each input data block being writable in A/k0 storage fields where k0 is an integer ≧2. For successive groups of k0 blocks, the k0 blocks are written to respective sub-arrays, each of A/k0 storage fields, of the storage field array by selectively writing at one of a series of rates, ranging from 1 block at a time to k0 blocks at a time, in dependence on a desired data write-rate. The blocks can also be read from the sub-arrays by selectively reading at one of a series of rates, ranging from 1 sub-array at a time to k0 sub-arrays at a time, in dependence on a desired data read-rate.

    摘要： Modems, methods, and computer program products for falling back to a low speed mode of operation upon detection of abnormal line conditions during startup perform a first phase of a multiphase startup procedure in accordance with a high speed mode of operation. A determination is then made whether the line conditions will support high speed communication. If a high speed connection cannot be established, then subsequent phases of the startup procedure will be performed in accordance with the low speed mode of operation. Otherwise, subsequent phases of the startup procedure will be performed in accordance with the high speed mode of operation. By detecting abnormal line conditions, such as digital discontinuity, severe attenuation, or a local loop having a non-linear frequency response, early in the startup protocol, the remainder of the startup protocol can be performed in accordance with a low speed more of operation as the detected abnormalities in the communication path will prevent the establishment of a higher data rate connection. Accordingly, the reliability and efficiency of the startup protocol are improved.

    摘要： A convolutional encoding/decoding system encodes a data bit stream into n bit parity sets from k bit data bit sets, using code words of length L. The system is dependent upon the finding that unique data to parity tables can be generated where both data and parity bit blocks are w bits in length. The value of w=n(L-k)/(n-k). An encoded parity bit stream is subjected to Exclusive OR operation through a connection mask or masks that are dependent upon the encoding code words. The Exclusive OR operation generates syndrome symbols indicative of the presence of errors in the parity bit stream and which are employed to address a correction table. Parity correction values are derived from the correction table and are used to revise the parity bit stream, which is then decoded, using a parity to data table. A number of parity correction procedures are disclosed.
