Abstract
Embodiments of the invention provide a retaining ring attaching device capable of improving assembling efficiency and a data storage device fabricating method. In one embodiment, a C ring attaching device included in a hard disk drive assembling apparatus expands a C ring, puts the expanded C ring on a pivot, and contracts the C ring on the pivot. The C ring attaching device moves chuck arms holding the C ring such that the C ring is moved so that a gap in the C ring moves away from the pivot while the C ring is being contracted.
