Abstract
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.
Claims20
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.
A computer-readable storage medium having processor-executable instructions stored thereon that, when executed by a processor, cause the processor to:
- detect an instability in a head of a storage device;
- in response to detecting the instability in the head, utilize a heater internal to the storage device to apply a thermal shock to the head to stabilize the head;
- determine whether the head is recovered;
- and
- in response to determining the head is not recovered, cause the application of the thermal shock to the head to be repeated.

A system comprising:
- a storage device comprising a reader head and a head heater;
- a processor operably connected to the storage device;
- and
- a thermal shock recovery module operably connected to the processor and configured to cause the processor to
- detect an instability in the reader head, and
- in response to detecting the instability in the reader head, cause a thermal shock to be applied to the reader head utilizing the head heater when the reader head is in an unload state.
