Abstract
A base plate is a portion of a housing of a hard disk drive, and includes a cast base body. The base body includes an inner surface including an inside machined surface that is machined and an inside non-machined surface that is not machined. The base body includes an outer surface including an outside machined surface that is machined and an outside non-machined surface that is not machined. The outside machined surface and the inside non-machined surface overlap in an axial direction that is a direction parallel or substantially parallel to a rotation axis of a disk of the hard disk drive.
