Abstract:
A disk apparatus includes a disk, a head, a circuit board, and an abnormality detection circuit. The head includes a plurality of loads, including at least a first load and a second load, associated with writing or reading of data to or from the disk, and a plurality of head terminals corresponding to and connected to the plurality of loads, respectively. The circuit board includes board terminals corresponding to and connected to the plurality of head terminals, respectively, and a preamplifier that applies a voltage to the loads via the plurality of board terminals during writing or reading of the data to or from the disk. The abnormality detection circuit detects a short-circuit between a first board terminal, which is the board terminal connected to the head terminal of the first load, and a second board terminal, which is the board terminal connected to the head terminal of the second load.

Claim (Index 15):
A pre-amplifier circuit for a disk apparatus comprising:\n a plurality of terminals including first, second, and third terminals in order with no other terminal between first and second terminals and no other terminal between the second and third terminals, the first and second terminals for connection to a first load on a magnetic head, and the third terminal for connection to a second load on the magnetic head and not to the first load; a plurality of abnormality detection circuits; and a plurality of inter-terminal abnormality detection circuits, wherein one of the abnormality detection circuits is configured to detect a short-circuit between the first and second terminals, and one of the inter-terminal abnormality detection circuits is configured to detect a short-circuit between the second and third terminals.
