Abstract
Method and apparatus for managing a data storage system that utilizes heat assisted magnetic recording (HAMR). In some embodiments, the method includes recording data to a storage medium using the HAMR system, accumulating a usage statistic indicative of actual elapsed operation of the HAMR system, and setting an indication value in a memory indicative of an estimate of remaining available elapsed operation of the HAMR system. The estimate of remaining available elapsed operation is determined in relation to the usage statistic and an estimated total elapsed operation value.
