Show moreIn the illustrated embodiment a video cartridge contains an endless loop record tape with a multiplicity of channels, and a pair of pivotal guide arms for holding a length of tape in a taut condition to facilitate loading of the cartridge with the tape threaded between a capstan drive assembly and a transducer head. The downward movement of the cartridge into the operative position serves to retract the tape guides clear of the operating tape path. A tape tension arm is provided along the tape path in the cartridge and is so arranged as to apply tension to the tape as the cartridge is unloaded from the transducing machine. The tape reel in the cartridge is suspended on a bearing ball so as to provide very low resistance to rotation. Sponsorship: IIT Research Institute United States Patent Show less

Show moreThe present invention relates to the magnetic recording of televisions signals. The source of video signals is a television receiver. Adapter circuitry is disclosed which includes a detachable cable for coupling the magnetic transducing heads with the video output of the receiver for the purpose of recording the broadcast signal or the display of the reproduced video signal derived from the tape. Detachment of the cable places the television receiver in a condition to allow the display of the broadcast video instead of recording the broadcast video signal.
