摘要：
A disk device has a housing structure capable of reducing unnecessary vibrations of the base of the disk device by improving the rigidity thereof. A bath-tub type base of the disk device includes a damping structure on the bottom or on the sides adjacent to the bottom for attenuating the vibrations of the base. Apparatus for writing a reference signal into the disk of the device using a reference head with a head insertion hole formed in the base is also provided.
