ABSTRACT:
A disk-jacket assembly including a flexible disk rotatably disposed in a square jacket having radially extending registering slots in its two thicknesses for receiving a pair of opposite transducers or alternately a single transducer in one slot and a pressure member in the other slot. Panels of porous low friction dusting fabric are disposed between the faces of the disk and the opposite inner faces of the jacket. The dusting fabric has slots coincident with the slots in the jacket, and the dusting fabric slots are wider than the jacket slots particularly for spacing the disk entry side edges of the jacket slots from the adjacent edges of the fabric to substantially prevent loose fibers on the fabric extending into the jacket slots.
