HAMR drive fault detection system

摘要

An apparatus of the present disclosure includes a controller coupled to a read/write head wherein the controller is configured to perform various operations. More specifically, the controller is configured to monitor an operational parameter of the read/write head and to detect a fault based on the operational parameter. The fault indicates that a write enabling energy source is malfunctioning during a write operation. The controller is additionally configured, in response to the fault, to take remedial action to protect data associated with the write operation.
