Continuous audio and video tape

Claim 1

A magnetic tape cassette for use in a magnetic tape recording and/or reproducing apparatus, the cassette comprising: a casing for housing a magnetic tape, said magnetic tape having two ends connected together continuously forming one endless loop; at least one hub rotatably mounted within said casing for rotationally engaging a driving shaft of said recording and/or reproducing apparatus; at least one conveyor assembly, frictionally coupled to said hub, for imparting motion to said magnetic tape housed within said casing; said conveyor assembly further comprising a plurality of guide rollers rotatably disposed about an outer circumference of said hub and an endless belt entrained about said plurality of guide rollers for frictionally coupling a rotation of said hub to said magnetic tape; at least one lever arm assembly coaxially disposed about said hub and connected to said endless belt of said conveyor assembly, whereby motion of said endless belt imparts circumferential motion to said lever arm assembly; said lever arm assembly comprising a lever arm, said lever arm including a plurality of lever arm pinch rollers rotatably disposed on a distal end of said lever arm for guiding said magnetic tape about said hub; a plurality of stop pins mounted within said casing adjacent said hub for limiting circumferential travel of said lever arm; wherein said hub engages said driving shaft of said recording and/or reproducing apparatus, a rotational force of said driving shaft is transmitted to said hub and said endless belt of said conveyor assembly thus imparting motion to said magnetic tape frictionally coupled thereto, said magnetic tape being coiled circumferentially about said hub by an oscillatory motion of the lever arm coupled to said endless belt such that the coiled magnetic tape remains substantially within a plane parallel to said hub.
