Provided are methods and systems (10, 110, 130, 152, 160, 170, 190) of encoding and decoding techniques in an optical storage system having a multi-head detector (108). In one embodiment, source data (112) may be encoded using error correction coding (e.g., turbo coding) techniques, and the encoded data (120, 126) may be interleaved and distributed to more than one detector head (106) of the multi-head detector (108). Data recorded (120, 126) in an optical disc (12) may be retrieved by the multi-head detector (108), and a read data (132, 140) from more than one detector head (108) may be concurrently decoded to retrieve estimates (138, 144) of the original information in the source data (112). Further, more than one encoder/decoder (116, 122, 136, 144) may be used, and each encoder/decoder (116, 122, 136, 144) may encode or decode data from multiple data heads (106, 108). Some embodiments also include replicating multiple discs (12). |
