ABSTRACT:
A method and system for resolving error or erasure in binary data streams read back using MR heads from a cyclic, multitracked recording medium. The method assesses whether an erasure or error was coincident with a thermal asperity. If the coincidence occurred, the method branches to and executes an ordered list of data recovery procedures tuned to thermal asperity. This list emphasizes early use of burst ECC correction and alteration of MR head and read channel attributes.
