Device and method for extending error correction beyond one sector time

摘要

Disclosed is an error detection and correction device for extending error correction time on a data sector beyond the time to receive a next data sector. The error detection and correction device is coupled to sequentially receive a plurality data sectors from a data storage medium. The device includes a buffer and error detection and correction circuitry. The buffer is configured to sequentially receive and store the plurality of data sectors from the data storage medium. The error detection and correction circuitry is configured to sequentially receive the data sectors for sequentially detecting errors in each of the received data sectors. The error detection and correction circuitry corrects the detected errors in the associated sector that is stored in the buffer beyond the time to receive a next data sector in sequence.
