ABSTRACT:
Apparatus for encoding digital data in accordance with an error protection product code into C1 codeword and C2 codewords, and storing such codewords on a plurality of parallel recording tracks on a record carrier. The code symbols of a given C1 codeword are assigned to a segment of a single storage track. The number of code symbols in a C2 codeword are a multiple of the number of tracks, and are cyclically assigned to segments of all tracks and cross intersegment boundaries, the physical spacing between adjoining symbols of a C2 codeword being substantially uniform in both coordinate directions. The storage requirements of the coding apparatus can be reduced if the number of symbols in each C2 codeword is an integral multiple of the number of tracks. In both the encoder and decoder, the RAM for storing codewords is organized so that the addresses of the symbols of any codeword have a 1:1 correspondence with the positions of such symbols on the tracks.
