Abstract
Embodiments of the invention provide a hard disk drive base adapted to prevent release of a strain due to the difference in thermal expansion between the vice coil motor and the base and thereby prevent a degradation in the positioning accuracy of the magnetic head. In one embodiment, a hard disk drive base is provided which includes a plurality of contact surfaces to which a lower yoke of a voice coil motor is fixed and thin portions each formed around a respective one of the plurality of contact surfaces and having a thickness smaller than that of other portions of the base.
