Abstract
A Reed-Solomon type error correction device carries out correction passes, and includes a first memory containing DVD type data, as well as CD type data after a first correction pass, for deinterleaving of the CD type data before a second correction pass. Additionally, a second memory of smaller capacity than the first memory, is provided for containing CD type data before correction, as well as deinterleaved CD type data. The invention concerns the error correction device and an optical disk reader containing such a device.
