Abstract

Data reliability at the output of the error-correction code decoder in a compact-disc system is influenced by the decoding strategy employed by the decoder, as well as by the statistical distribution of errors that contaminate the recorded data. Recovered-data reliability estimates have been computed by use of error statistics obtained from the measurement of errors that contaminate the actual data stored on clean write-once and read-only-memory compact discs. These estimates consist of probabilities that specify the occurrence of residual errors in the data that appear at the output of a compact-disc player’s cross-interleaved Reed–Solomon code (CIRC) decoder. Data reliability estimates that apply to five specific CIRC decoding strategies are reported.
