ABSTRACT:
A protective tab for floppy disks having an opening that is designed to be covered to prevent accidental erasure of any recording thereon. The protective tab has an integral clamshell construction such that it can be pried opened to be positioned over the floppy disk jacket opening and snapped closed to engage the border of the floppy disk jacket and cover the opening. A characterized opening having a narrow throat is punched out over the regular opening in the floppy disk jacket. This opening can either be manufactured into the floppy disk jacket, or retrofitted into a pre-existing conventional disk jacket by use of a special punch which is provided for cutting out the characterized opening. The protective tab has a mating characterized pad on the inside of one of the clamshell halves which is inserted in the disk opening. When closed the protective tab can not be accidentally pulled out unless purposely opened.
