Disk drive including resilient securing system providing relative movement between side rails and head disk assembly to accommodate side rails engaging guide channels in a chassis

Abstract

A disk drive is usable in a chassis having first and second guide channels mounted on side surfaces of the chassis. The disk drive includes a head disk assembly that includes first and second side walls. The disk drive further includes first and second side rails and a securing system for securing the side rails to the side walls. The first and second side rails engage the first and second guide channels, respectively, for supporting the disk drive within the chassis. The securing system includes an engagement mechanism and a double-sided adhesive resilient mechanism. The engagement mechanism projects between the first and second side rails and the first and second side walls, respectively, of the head disk assembly. The double-sided adhesive resilient mechanism is adhesively attached between the first side rail and the first side wall and between the second side rail and the second side wall for mounting the first and second side rails to the first and second side walls, respectively, of the head disk assembly. The securing system provides for relative movement between the side rails and the side walls to accommodate the side rails engaging the guide channels in the chassis. In one embodiment, the relative movement is a damped relative movement.
