Abstract
A base for a magnetic storage device includes a baseplate, sidewalls extending from the baseplate, and an interior cavity defined by the baseplate and the sidewalls. The baseplate includes an exterior surface and an interior surface opposite to the exterior surface. The interior surface at least partially defines the interior cavity. The interior surface includes a substantially planar surface and grooves formed in the substantially planar surface. A thickness of the baseplate varies. A minimum thickness of the baseplate is defined by at least one groove of the grooves.
