Magnetic disk drive in which a body including a chassis is rotatable with reference to a location displaced from the center of gravity of the body

摘要

A magnetic disk drive including a body including a chassis (1) formed of a flat plate, and at least a spindle motor (8) and a head carriage (5) that are mounted to the chassis; a bottom cover (9) mounted so as to cover the chassis; and holding means (10, 11) (such as a screw) for holding the chassis and the bottom cover; wherein the holding means is disposed on a support line Y-Y which extends perpendicular to a line X-X passing through the center of gravity of the body extending in a direction of movement of the head carriage and which is displaced from the center of gravity of the body; and wherein the body is rotatable with respect to the bottom cover, with the support line Y-Y as an axis. <IMAGE>
