Abstract

One embodiment of the invention includes a disk-drive write head fault detection system. The system includes an output stage configured to generate a monitored current through the disk-drive write head. The system also includes an open-circuit fault detector configured to compare a magnitude of a first reference current with a magnitude of the monitored current to detect an open-circuit fault condition associated with the disk-drive write head. The system further includes a short-to-ground fault detector configured to compare a magnitude of a second reference current with the magnitude of the monitored current to detect a short-to-ground fault condition associated with the disk-drive write head.
