Abstract

This write protect tab is designed so that it can be secured to a floppy disk jacket without adhesive, enabling it to be mounted upon or removed from the disk unit as many times as desired without adverse effect upon either the tab or the disk jacket. The conventional write protect tab is provided with glue or other adhesive on the surface which contacts the floppy disk jacket. If the disk user subsequently wants to perform a write operation on the disk, he must pull off the tab, leaving glue on the disk jacket and usually damaging or destroying the tab. To eliminate this problem, it is proposed herein to use a non-adhering, easily removable and reusable tab for write protect purposes. Two types of this reusable tab are illustrated. Fig.

Reusable Write Protect Tab for Floppy Disk

This write protect tab is designed so that it can be secured to a floppy disk jacket without adhesive, enabling it to be mounted upon or removed from the disk unit as many times as desired without adverse effect upon either the tab or the disk jacket. The conventional write protect tab is provided with glue or other adhesive on the surface which contacts the floppy disk jacket. If the disk user subsequently wants to perform a write operation on the disk, he must pull off the tab, leaving glue on the disk jacket and usually damaging or destroying the tab. To eliminate this problem, it is proposed herein to use a non-adhering, easily removable and reusable tab for write protect purposes. Two types of this reusable tab are illustrated. Fig. 1 shows a tab in the form of a small plastic sheet molded into a U shape with its legs spaced closely enough to have a firm frictional grip upon the disk jacket (approximately 0.010 inch apart). Fig. 2 shows a tab of similar construction adapted to be slid into or out of a suitable channel formed in the jacket of the disk unit, with a small handle provided on the tab so that it can be manipulated mechanically if desired. Neither of the illustrated tabs relies upon the use of adhesive, which would be employed only if the tab is to be permanently affixed.
