ABSTRACT:
The present invention relates to an apparatus and method for detecting and correcting burst errors of indeterminate length occurring in data entered along a magnetic tape or other storage medium. An encoder and decoder arrangement is provided wherein parity or check bytes are encoded and decoded across data blocks which are measured along and across the tracks of the storage medium and wherein the parity or check bytes are read onto separate tracks of the storage medium. The present invention provides for the continuous encoding and decoding of data because the parity bytes and data bytes are conveyed to and from the storage medium along separate tracks.
