Abstract
In an iterative error correction method and apparatus for correcting errors in digital data read from a storage medium, re-reads are combined with the error correction procedure in a single error recovery procedure. The data read from the storage medium are represented as a multi-dimensional data structure, and the error recovery procedure is undertaken for each dimension of the data structure. In each dimension, an erasure map is generated that contains errors in the initial read of the data for that dimension, and the errors in the erasure map are deducted as they are corrected in subsequent re-reads. After a predetermined number of re-reads, or when no further errors exist, the error recovery procedure is ended.
