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 11):
The method of  claim 1 , wherein the first and second data transducers are characterized as heat assisted magnetic recording (HAMR) heads each having a laser diode and a near field transducer (NFT) which cooperate to irradiate localized regions of the respective first and second rotatable data recording surfaces with electromagnetic radiation as an associated magnetic write element in each of the respective first and second data transducers applies a magnetic write field to the localized region to record data thereto, wherein the operational life metric value represents a write power on hour (WPOH) value associated with consumed or remaining time, and wherein the data are subsequently transferred from the local memory to the second rotatable data recording surface responsive to the first transducer having a higher WPOH value as compared to the second transducer.
