Abstract:
1. An error correction encoding method comprising: generating error correction code data, which has first bytes, by error-correction-encoding user data in a predetermined manner; generating burst indicator subcode-data, which has second bytes and is used to detect errors that have occurred in the user data; dividing the error correction code data into a plurality of sub-error correction code data each having a length that is less than the error correction code data; dividing the burst indicator subcode data into a plurality of sub-burst indicator subcode data having a length that is less than a minimal data unit that is error-correction-encodable; and alternately arranging the plurality of sub-error correction code data and the plurality of sub-burst indicator subcode; and recording the arranged sub-error correction code data and sub-burst indicator code data onto a recording medium.
