<p>An error correction apparatus for use in erasure correction and error correction in transmission paths of devices such as optical disk devices, upon receipt of input data of various formats. The apparatus has a select signal generating circuit for generating, in response to the format of the input data, a select signal corresponding to the format of the input data. An erasure correction and error correction circuit for conducting error correction including erasure correction; and a controlling circuit for controlling the erasure correction and error correction means in accordance with the select signal so as to conduct correction in conformity with the format of the input data. Thus, the erasure correction and error correction can be conducted regardless of format of the input data.</p> |
