Abstract
Methods and apparatus to monitor and control hard-disk drive head position are described. In one example, a hard-disk drive system includes a hard-disk drive platter, a hard-disk drive read head configured to read information from the hard-disk drive platter, and a hard-disk drive head position controller configured to a receive a signal via the hard-disk drive read head and to determine if the received signal indicates that a distance between the hard-disk drive platter and the hard-disk drive is less than a predetermined distance and to vary a temperature of the read head based on the determination.
