Abstract
A method and apparatus for Read-After-Write (RAW) verification with error tolerance is disclosed whereby upon read back of data from a medium, the actual read data can be compared to the actual write data, and the number of miscompares between the two can be counted. The severity of the number of miscompares can be determined depending on the Error Control Code (ECC) system used. If the error is correctable by the ECC system, the block need not be re-written to the medium. The invention provides the ability to increase medium capacity and throughput over previous implementations.
