ABSTRACT:
Prior magnetic recording diskettes have a wiping fabric, edges of which register with edges of jacket openings, thus involving a hazard of loose fibers. In the novel diskette, the edges of the wiping fabric are out of registry with the edges of the jacket openings. This not only avoids the hazard of loose fibers, but a die with which the jacket is cut remains usefully sharp for at least twice as long as it would if used to die-cut a composite of the jacket material and fabric as in the prior art. Also, the punched-out pieces of jacket material are uncontaminated by fabric and so can be reused as scrap. Preferably, the wiping fabric is separated along the line at which the jacket blank is centrally folded to form an envelope for a recording disk. By eliminating fabric at the central jacket fold, surprisingly lower temperature has been necessary to form the fold, thus eliminating distortions in the jacket at the central fold.
