Abstract
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=k.A where r is the number of codewords and kis an integer≧1. A sub-blocks of kbytes 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.
