This is a system for modification of floppy diskettes e.g. 8'' or 5 1/4'' for software used in computers and peripheral equipment, making it possible to alter their original storage capacity of information on the magnetic surfaces, or disks. The modification is achieved by creating special holes or perforations, for optical and magnetic decoding. These new holes are produced symmetrically on both sides of the black protective cover of the disk or on its edge(s). The system uses a combination of a template (1) which is hollow and consist of two identical incomplete rectangulars surfaces, closed at (7a), (7b) and open at (3a), (3b). Each surface being equipped with positioned semicircles (1a), (1b) and U-shaped openings through both surfaces (1c), (1d), (1e), (1f). Also, an angled alpha punching-tool (9) consisting of two cutting jaws (10a), (10b) which when closed lie inside each other, forming an internal U-shaped space, and which are connected to the handles (11a), (11b). A floppy diskette can be inserted into the template or guide (1), and after adjustment of corner (8a) with corner (8b) and positioning of areas (1a) with (5a) or (1b) with (5b), the front part of the hole-punching tool (9a) of (9), can be put in such a position that the closing of the cutting jaws (10a), (10b) results in cutting a hole e.g. (2b) on the diskette cover (2a); the shape of the hole determined for ex. by the contour of a U-shaped opening e.g. (1c) of the template or guide (1). |
