Abstract

Magnetic recording disks, such as disk 1, are held by a robot end effector at three points on their circumference. The gripping elements are three externally-grooved rollers 2, two of which are mounted on a common limb 3. The robot moves one or both sets of rollers inwardly by means of arms 4 to locate on the disk edges. This movement centres the disk with respect to an axis defined by the end-effector. The ability of the rollers to rotate freely as the disk is engaged assists centering and limits the possibility of chafing which could generate particulate contamination. When the disk is securely centered, it may be assembled by the robot onto the hub of a disk file.
