A lightweight, limited use video cassette cartridge that performs all of the needed functions of permanent-use video cassette cartridges, but comprises only eight parts, all made of thin gauge, recyclable synthetic resin material. The lightweight video cassette cartridge includes a top panel and a bottom panel which are mated to form the cartridge shell, a supply reel and a take-up reel rotatably mounted within the cartridge shell, a novel mechanism for maintaining the position of the reels within the cartridge while in use, leader tape for attaching the recorded video tape to the reels, two pieces of low coefficient Teflon tape, and a removable dust cover to protect the exposed video tape. The cartridge weighs less than 1.3 ounces when completely assembled and can be recycled without removing parts.
