Abstract

When detecting errors on recording media where the error area cannot be related to data sequences surrounding the area, a fault-indicated error can result in data integrity exposures. Generally, errors are logged in a priority list such that if multiple errors are simultaneously detected, only the highest priority error is logged. Upon detecting any error on a magnetic recording medium, a plurality of retries are employed to recover. During such plural retries, if an error other than a predetermined error occurs, then a combination of the two errors adjusts the priority of the errors such that alternate recovery is employed; i.e., in a magnetic medium an alternate or secondary area is accessed.
