The present invention provides an error correction method and apparatus, and also an optical disc playback method and apparatus. The error correction method in the present invention is used to perform error correction on data read from an optical disc, comprising: obtaining the error detection information of a block corresponding to the read data; determining data error type in a data stream unit derived from the block according the error detection information; according to the data error type and predefined reference error type, judging whether to reserve the data stream unit for optical disc playback. By using the error detection information of the block which is discarded by using the existing technologies, the player can perform further error correction to try to avoid data errors which may produce interruption during optical disc playback. ® KIPO & WIPO 2008
