ABSTRACT:
A hard disk drive that includes an optical pick-up coupled to a head of a hard disk assembly (“HDA”). The head is located adjacent to a disk. The optical pick-up can sense the surface of the disk by detecting light reflected from the surface. The optical pick-up is coupled to a particle circuit that can distinguish between an embedded particle and a floating particle from the reflected light.
