Abstract
A code error corrector that enables high speed reproduction of DVD data with a high error correction capability. The data read from the DVD is stored in a DRAM. A PI correction circuit, which performs error correction with an inner parity, and a PO correction circuit, which performs error correction with an outer parity, alternately perform error correction for a predetermined number of times on the data stored in the DRAM. The detection circuit checks whether an error is included in the error corrected data whenever error correction is performed. If an error is not detected, the repeating of the error correction is stopped even if the error correction has not been performed for the predetermined number of times.
