ABSTRACT:
Disclosed is a magnetic disk apparatus comprising: a disk enclosure; a first printed-circuit board which is paired with the disk enclosure; and a second printed-circuit board which is connected to the first printed circuit board via a cable and is separated from the first printed-circuit board in structure; wherein the first printed-circuit board mounts circuits which are poor in noise resistance property, and a circuit which holds parameters unique to the disk enclosure; and wherein the second printed circuit board mounts circuits which are superior in noise resistance property.
