Abstract
A method of coupling a voice coil motor to a bowl-type base plate of a hard disk drive is described for a hard disk drive including a voice coil motor having a coil coupled to a rear end portion of an actuator arm, an upper yoke and a lower yoke provided at upper and lower portions of the coil respectively, a bowl-type base plate having a plurality of flattened structures for fastening the lower yoke in a position relative to the bowl-type base plate and a countersink formed in the lower yoke. The method includes inserting a countersunk head screw into the countersink and coupling the head screw to a screw coupling hole provided in a first support portion of the bowl-type base plate to fix the lower yoke to the bowl-type base plate, wherein the first support portion protrudes to a predetermined height and is formed around the screw coupling hole provided in the bowl-type base plate
