Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
1 A rigid floppy disk cartridge (10) comprising a rigid jacket (13,17) defining a flat, substantially closed cavity, the jacket including a through-hole (15,16) and at least one head-receiving aperture (21,22) in a flat portion of the housing, a generally flat floppy disk (18) nonremovably loosely housed within the cavity, the disk including a mounting aperture (19) aligned with the through-hole, but smaller in dimension than the through-hole, and a rigid, movable disk cleaning member (29;50;129) formed as a part of the rigid jacket, the cleaning member being normally spaced from the disk and being adapted to be moved into the cavity and into cleaning contact with the disk.
Claim 2
Dependent Claim
109 words
1 A rigid floppy disk cartridge (10) comprising a rigid jacket (13,17) defining a flat, substantially closed cavity, the jacket including a through-hole (15,16) and at least one head-receiving aperture (21,22) in a flat portion of the housing, a generally flat floppy disk (18) nonremovably loosely housed within the cavity, the disk including a mounting aperture (19) aligned with the through-hole, but smaller in dimension than the through-hole, and a rigid, movable disk cleaning member (29;50;129) formed as a part of the rigid jacket, the cleaning member being normally spaced from the disk and being adapted to be moved into the cavity and into cleaning contact with the disk.
Claim 3
Dependent Claim
66 words
2 A cartridge according to claim 1, in which the disk cleaning member (29;129) comprises a loose, rigid housing piece which has a cleaning surface (32;46) on the side thereof facing the cavity, the rigid housing having an aperture (27;127) closed by the housing piece, the housing piece being constrained from movement out of the aperture by confining housing surfaces (28;128) formed in the rigid jacket.
Claim 4
Dependent Claim
32 words
3 A cartridge according to claim 2, in which the surfaces (28;128) of the rigid housing which confine the housing piece overhang the aperture (27;127) to trap the piece in the aperture.
Claim 5
Dependent Claim
47 words
4 A cartridge according to claim 1, in which the disk cleaning member (50) comprises a rigid housing piece which co-operates with a cleaning surface (32;46) on the side thereof facing the cavity, the housing piece being connected to the rigid jacket by a reduced-thickness hinge (51).
Claim 6
Dependent Claim
51 words
5 A cartridge according to claim 1,2,3 or 4, in which the wall of the cavity opposite the disk cleaning member includes a stationary second disk cleaning surface (45), whereby both sides of the disk are cleaned when the movable disk cleaning member is moved into cleaning contact with the disk.
Claim 7
Dependent Claim
59 words
6 A disk drive (60) for a cartridge according to any preceding claim, including a rotatable collet member (64) for mechanically clamping the disk for rotation about an access with the through-hole, and a movable force member (80), operable after the collet member has clamped the disk, to move the disk cleaning member into cleaning contact with the disk.
