RIGID FLOPPY DISK CARTRIDGE

摘要

A flexible magnetic recording disk is nonremovably enclosed in a rigid jacket. A wall of the rigid jacket includes a movable wall-piece 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.
