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: To reduce the risk of contamination by pieces of the wiper lining becoming detached, the transducing apertures (511;513), in the wiper lining (502, 503, 504, 505) of a flexible magnetic data storage disk/jacket assembly, are cut to larger dimensions than the jacket apertures (28X) registering therewith are punched to. Preferably the wiper lining is cut into two parallel separated strips, and after the fixing of the strips to the jacket blank (118 X) the blank is punched in the aperture defined by the gap between the strips. A single wiper lining aperture can accommodate two registered jacket apertures which can be off-centre with respect to the wiper lining aperture.
