ABSTRACT:
A video recording and playback device with a built-in video camera includes an outer case having the same profile as that of a tape cassette that can be inserted into an exiting stationary video tape recorder. The outer case houses a pair of rotatable reels, a magnetic tape wound around the reels, a magnetic head drum for recording signals on the magnetic tape, magnetic tape guide posts for guiding the magnetic tape to run on and around the magnetic head drum a magnetic tape transport unit for transporting the magnetic tape from one of the reels to the other reel, an imaging unit for producing a video signal representative of an image of an object, a signal recording circuit for processing the video signal from the imaging unit and enabling the magnetic head drum to record the video signal on the magnetic tape, and a power receiving terminal assembly for receiving electric power to energize the motor of the magnetic head drum, the magnetic tape transport unit, the imaging unit, and the signal recording circuit. A recording medium such as a magnetic sheet disk or an optical disk may be employed instead of the magnetic tape.
