Abstract:
1. A disk drive apparatus comprising: an enclosure; a head that accesses a disk; an actuator that is mounted inside the enclosure comprising a plurality of arms that supports a plurality of heads and pivotally moves about a pivot; a resin member that is fixed to a side surface of each of said plurality of arms of the actuator, the side surfaces each facing a pivotal motion direction, having a recess facing said pivotal motion direction, through which a wire structural portion transmitting signals from the head is passed, formed on a side opposite to the side surface, and having a corrugated surface structure for positioning correctly the resin member in a pivot direction by being fitted into a corrugated surface structure formed on the side surfaces, such that said wire structure portion faces said pivotal motion direction; wherein the resin member includes a plurality of protrusions protruding toward each of the corresponding recesses of the side surfaces; and wherein the recess in each of the side surfaces of each of the plurality of arms of the actuator, in which the protrusion of the resin member fits, extends beyond both ends of the protrusion of the resin member in a direction from the pivot toward the head.
