Storage device head instability recovery by heating from head heater

摘要

Technologies are described herein for recovering an instable head in a storage device using an internal head heater. An instability in the reader head may be detected, and, in response to detecting the instability, a thermal shock may be applied to the reader head utilizing the head heater to recover the head.

主权项

1. A method comprising steps of:
detecting, by a controller in a storage device, an instability in a reader head of the storage device; and in response to detecting the instability in the reader head, applying, by the controller, a thermal shock to the reader head utilizing a head heater, the thermal shock thermally baking the reader head to lower the energy state of the reader head.
