Abstract

A micro-floppy diskette has an outer relatively rigid jacket with a pair of aligned transducer access apertures; an inner containment cup assembly rotatably received within the jacket, the cup assembly including a pair of flexible cups sealed about the periphery and a pair of flexible annular wiping elements secured to the inner surface of each cup member; and a flexible recording disk rotatably received within the cup assembly. The cup members and wiping elements have mutually aligned cut-out portions which expose the disk recording band through the jacket access apertures when the cup assembly is rotated to an open position. When the cup is rotated to a closed position, the recording disk is shielded from ambient by solid portions of the jacket. One of the cup members has a protruding lug arranged in sliding contact with an inner surface of the jacket to bias the disk to a disk operating plane when the cup assembly is in the open position. An inner surface of the jacket has a detent groove which receives the lug when the cup assembly is in the closed position to provide a positive detent shutter function. An optional tension spring normally biases the cup assembly to the closed position.
