Abstract

Disclosed is a data recovery method for disk storage devices by applying matrix ECC (Error Correction Code) for a block of sectors. This method allows long burst data error correction capability with little loss of the data capacity and the performance. The configuration of a block is, j (integer) sectors are appended as the matrix ECC for leading k (integer) data sectors such as, Sector_1, Sector_2,,,, Sector_k, ECC_sector_1, ECC_sector_2,,,ECC_sector_j
