Abstract
An adaptor for converting a video cartridge to a videocassette format. The adaptor includes a tether band which is used to draw tape from the cartridge and guide the tape across the tape path to a take-up reel inside the adaptor. The tether band is a self supporting cantilever structure eliminating the need for a positive locking clasp connection between the tape and the tether. A single axis non clasping interconnector for use with the band is shown with complimentary alignment zones.
Claims5
A two-piece videocassette comprising:
- a cartridge for insertion into a cartridge adaptor, said cartridge and said cartridge adaptor together forming said two-piece videocassette;
- said cartridge having a rotatably mounted tape supply reel for storing a length of magnetic tape, said supply reel having a supply reel hub;
- said length of magnetic tape having a first tape end and having a second tape end, said first tape end being attached ultimately to said supply reel, said second tape end being attached ultimately to a tape connector;
- said cartridge adaptor having a cartridge receiving cavity adapted to receive said cartridge;
- said cartridge adaptor having a tape path channel defining a tape path;
- said cartridge adaptor having a take-up reel located within said cartridge adaptor and mounted for rotation within said cartridge adaptor, said take-up reel having a take-up reel hub;
- said cartridge adaptor having a tether assembly, said tether assembly including a tether band, and a tether;
- said tether having a first tether end and having a second tether end, said first tether end coupled to said tether band, and said second tether end connected to said take-up reel hub;
- said tether band having a first tether band end and having a second tether band end, said first tether band end being coupled to a tether connector and said second tether band end being coupled to said tether;
- said tether connector and said tape connector together adapted for mating engagement forming an interconnection;
- whereby said tether band guides and supports said interconnection along said tape path channel;
- said tether band being flexible in a first plane defined by the plane of said tape path channel and being inflexible in a plane orthogonal to said first plane and wherein said tether band comprises a plurality of articulated links hinged together forming a self supporting cantilever assembly.
