Abstract: A flexible magnetic recording disk (18) is nonremovably enclosed in a rigid jacket (10). A wall (17) of the rigid jacket includes a movable wall-piece (29) which operates as a disk cleaning member. The disk is clamped to a spindle/collet drive assembly while the disk cleaning member is spaced from the adjacent surface of the disk. Only after clamping has been accomplished is the disk subjected to the friction force of the cleaning member.

Abstract: The burnishing tool has a plurality of holes (41) in the planar surface (40) which engages the flexible magnetic disk (4). Each hole contains a burnishing blade (42) positioned at 45° to the direction of motion. A manifold (20) connects each hole to a vacuum pump which draws air into the holes causing the flexible magnetic disk to fly against the planar surface. The vacuum also removes the debris from the burnishing tool.
