ABSTRACT:
A removable tape cartridge (14) for insertion into a carrier (12) in order to form a two-piece videocassette (10) comprises a housing (30) with a tape reel assembly (32) therein. The tape reel assembly (32) includes a length of tape (64) with a connector (68) at one end which, upon insertion of the cartridge (14), mates with an associated connector (16) in the carrier (12) to establish connection with a take-up reel (20). The tape reel assembly (32) is normally biased downwardly by a spring (56) and is normally constrained against rotation by an internal brake assembly (70-74) responsive to insertion of the cartridge (14) into the carrier (12). The tape connector (68) is releasably secured in proper position for mating engagement with the corresponding connector (16)by one end of an arm (78), the other end of which functions to interlock the tape cartridge (14) and carrier (12) against separation upon withdrawal of the tape.
