DATA TRANSFER METHOD, BLOCK SYNCHRONIZING SIGNAL DETECTING METHOD, AND REPRODUCING APPARATUS |
摘要 |
There is provided a method of detecting a block sync signal in which a sync signal and code sequence can be distinguished from each other to recognize the head of a block composed of a plurality of code words at the time of data reading or reception. A sync word detector ( 10 ) is supplied with a window signal Sync_window generated based on a parity OK signal supplied from a parity check circuit ( 12 ) and indicating a period between the sync word included in signal read from the medium ( 1 ) and the ID information, and detects the sync word as to a bit string detected by a PRML Viterbi detector ( 6 ) with the use of the Sync_window signal.
