Abstract
An EFM data decoding method and apparatus thereof for optical disk system is provided. According to the method, a 14-bit data complying with the EFM modulation criteria but failing to correspond to a 8-bit data based on an EFM decoding table is transformed successfully by looking up an expanded EFM decoding table. The expanded EFM decoding table includes probable 8-bit data corresponding to the erroneous data complying with the EFM modulation criteria. Reliability of data reading is thus enhanced in the present invention.
