Abstract:
Method and apparatus for distributing wear in a data storage system. In some embodiments, a first data transducer is used to record data to a first data recording surface. Performance statistics are accumulated including a dwell metric value indicative of relative dwell time of the first transducer adjacent a selected radial location on the first data recording surface and an operational life metric value indicative of accumulated elapsed operation of the first transducer. A data migration mode is enacted to migrate data from the selected radial location to a local memory in a hierarchical memory structure responsive to at least a selected one of the dwell metric value or the operational life metric value. Host access commands are temporarily serviced from the local memory, after which the data are returned to the selected radial location or a new location in a disc stack main memory store.

Claim (Index 15):
The apparatus of  claim 12 , wherein the wear mitigation circuit comprises:\n a dwell monitor circuit configured to accumulate first and second dwell metric values for the respective first and second data transducers indicative of relative dwell times adjacent associated locations on the first and second rotatable data recording surfaces; an operational life monitor circuit configured to accumulate first and second operational life metric values indicative of accumulated elapsed operation of each of the first and second data transducers; a monitor circuit configured to compare the first and second dwell metric values to a first threshold and to compare the first and second operational life metric values to a second threshold; and a data migration circuit which migrates the data from the selected location to the local memory based on at least a selected one of a relative difference between the first and second dwell time values or a relative difference between the first and second operational life metric values.
