Abstract
Approaches for a hard-disk drive (HDD) baseplate comprising a recessed region that provides additional clearance for a disk. The protective enclosure of the HDD comprises a baseplate. The surface of the baseplate, which opposes a magnetic-recording disk, comprises a recessed region near the outer diameter (OD) of the magnetic-recording disk. The recessed region prevents the disk from being damaged through inadvertent physical contact with the baseplate, which may arise when the HDD receives a mechanical shock. The recessed region may be designed to minimize the damage to the disk if physical contact between the disk and the baseplate does occur. The recessed region may have a variety of shapes, such as a circular indentation or one or more non-contiguous regions in the baseplate where physical contact between the disk and the baseplate is deemed likely to occur.
