    摘要: A decoding apparatus for a high-density recording medium includes a demodulator, a long-distance code (LDC) processing module, a burst indicator subcode (BIS) processing module, an erasure code generator, and a decoder. The demodulator demodulates data from a high-density recording medium to obtain a demodulated data and a demodulation error flag. The LDC processing module and the BIS processing module deinterleave the demodulated data to respectively obtain an LDC data and a BIS data. The erasure code generator sets an erasure flag corresponding to the LDC data according to the demodulation error flag and the BIS error flag. The decoder decodes the LDC data according to the erasure flag. Further, the decoder decodes the BIS data to obtain the BIS error flag.

    摘要: A state modulation method and an apparatus for inserting state control codes are provided. To overcome the problems of inefficient control on direct current and low frequency component in conventional state modulation techniques, the disclosed method inserts state control codes in a state modulation method to increase the probability for selection. With multi-level characteristics, the inserted state control codes can provide a plurality of sets of different signals for selection during coding. Thereby, the direct current and low frequency components can be well controlled.
