    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.

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： 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.
