ABSTRACT:
A device and method are disclosed for forming the S-video record enable I.D. hole in VHS, 8 mm and VHS-C videocassettes. Three specially adapted hole forming implements and their method of use are described. These implements are adapted to avoid forming loose debris from the hole forming process and to prevent such debris which is created from entering the cassette mechanism. The invention provides for automatic positioning of the hole forming implements and for control of their movement by use of positioning plates which are specially adapted to fit on the videocassettes in a singular and specific manner. The invention further provides for controlling the operation and movement of the hole forming implements by use of guide bushings which are integral to the positioning plates. The methods used for forming the hole include cutting, piercing and melting through the plastic cassette shell.
