ABSTRACT:
An error correction apparatus includes: an error correction circuit6for performing a data error correction based on a first error correction algorithm selected from among a plurality of error correction algorithms having different correction strengths; an error determination unit8afor using the first error correction algorithm to detect that the data error correction has been disabled; and a computer8for selecting a second error correction algorithm from the plurality of error correction algorithms, and for controlling the error correction circuit6to use the second error correction algorithm to perform the error correction for data for which it has been determined that the first error correction algorithm is not capable of correcting errors in the data.
