Abstract
A mechanism for placing and removing a vacuum clamping device for a magnetic disk on a spinstand, comprised of automated vertical and horizontal movement arranged such that a vacuum disk chuck, comprised of a base (9) and cap (6), can be used without operator interaction. Linear actuators provide the horizontal (2) and vertical (3) movement forces to accurately move a chuck cap (6) over a magnetic disk (7) that has been placed on a chuck base (9). The same actuators remove the cap and move it away from the disk to allow quick replacement of the disk. The interface between the mechanism and disk chuck cap is designed such that the cap is securely held during motion, and does not create particles.
