Error correction method, apparatus and program product

An error correction apparatus for performing error correction for data to which error correction data have been added, comprising:

• an error correction unit configured to perform error correction for the data using a first error correction algorithm that has been selected from among a plurality of error correction algorithms having different correction strengths;
• a determination unit configured to determine whether or not the error correction for the data using the first error correction algorithm is capable;
• and
• a controlling unit configured to select a second error correction algorithm from the plurality of error correction algorithms and to control the error correction unit to perform error correction using the second error correction algorithm, for the data in which determined that the error correction using the first error correction algorithm is incapable.

An error correction program product for causing a computer system to execute procedures for performing error correction for data to which error correction data have been added, the program product comprising:

• a unit for selecting a first error correction algorithm from a plurality of error correction algorithms having different correction strengths;
• a unit for employing the selected first error correction algorithm to perform error correction for the data;
• a unit for determining whether or not the first error correction algorithm is capable of correcting errors in the data;
• a unit for selecting a second error algorithm from the plurality of error correction algorithms when it is determined that the first error correction algorithm is not capable of correcting errors in the data;
• and
• a unit for employing the selected second error correction algorithm to perform error correction for the data.
