Abstract
The present invention provides a method and system for error correction in optical media data processing. The method includes demodulating a data using a conversion table; marking errors which occur during the demodulation; utilizing estimated values for the marked errors; and performing error correction. The method and system marks errors which occur during demodulation. A logic array is used to obtain estimated values for the marked errors. The marking of errors and the use of values from the logic array for the marked errors increases the probability of the C1 and C2 correction processes being able to correct the errors. Fewer 'not correctable' data results. This increases the integrity of the read data.
