1. A disk device comprising:
a housing comprising a base including a bottom wall and a cover fixed to the base and having a height defined by a standard of 3.5-inch disk devices;
ten or more magnetic disks rotatably disposed in the housing;
a head actuator comprising a plurality of magnetic heads, an actuator block rotatably provided on the bottom wall, arms extending from the actuator block, and a suspension assembly attached to each arm and supporting at least one of the magnetic heads;
a flexible printed circuit unit disposed on the bottom wall in the housing and connected to the head actuator; and
a printed circuit board mounted with electronic components including an interface connector, a relay connector, and a motor drive IC, disposed to oppose an outer surface of the bottom wall at a location off from a region opposing the magnetic disks and off from a region opposing an area where the actuator block, the arms, and the suspension assemblies including the magnetic heads of the head actuator are movable, the printed circuit board being electrically connected to the flexible printed circuit unit through the relay connector.
