ABSTRACT:
An error detection and correction device in which a word train including a number of error correction codes each constructed from a plurality of words is input, the error correction code being of the type that two error words can be corrected by each error correction code. Error words are corrected by using the error correction code within the word train. Mode setting information associated with an error rate of the word train is generated, and an error correction means is controlled in a first or a second error correction mode depending on the mode setting. The error correction means corrects one or two error words for each error correction code in the first error correction mode and corrects only one error word for each error correction code in the second error correction mode.
