Paperboard micro computer diskette

Abstract

An improved micro computer diskette is constructed from a light-weight, foldable paperboard blank having nonwoven liner material bonded on its inner surfaces. The paperboard blank is scored with double score lines to form a hinged portion between diskette jacket halves as a leading edge of the diskette and three side edges with overlay flaps for securing the jacket halves together. Folding the paperboard blank along the double score lines and adhesively securing the overlay flaps produces a rigid cartridge structure for diskette use having liner material on its inner surfaces and external surfaces adapted for printing thereon with any desired graphics. The paperboard jacket halves are embossed in corresponding sections with offset ridges for lifting the liner material into cleaning contact with the disk media. Head slots are punched in the paperboard blank, and an externally removable tab with self-adhesive edges is used to cover the head slots.
