Abstract
An adaptive error recovery routine allows for the recovery from errors in read data of a disk drive. In one embodiment, a disk drive is provided which has an error memory having error memory elements used to record an error type and recovery step for each error recovered from the disk drive. If another error is detected that is of the same type and which is in a location close to a recorded error, the error recovery step used for the previous error is performed for the new error. If the previous error recovery step is not successful, the disk drive performs error recovery using an existing error recovery table, and omits the previous error recovery step.
