Abstract: A low noise loading motor drive circuit for a camera-integrated camcorder includes a rotation velocity detecting circuit for detecting a rotation number proportional to a velocity signal generated from the loading motor, a velocity signal strengthening amplifying unit for amplifying and strengthening the output signal from the rotation velocity detecting unit, and a velocity to voltage converting unit for converting the output signal from the velocity signal strengthening unit into a voltage inversely proportional to the velocity of loading motor. The circuit also includes a voltage limiting circuit for setting a rotation velocity range limited between a predetermined maximum rotation velocity and a predetermined minimum rotation velocity of loading motor, in a normal rotation made of loading motor. The voltage from velocity to voltage converting unit and the voltage limited output signal from voltage limiting circuit are summed by an adder.

Abstract: An apparatus and a method for loading a cassette tape in a video equipment, in which driving of a DC motor can be controlled according to an amount of load which is applied to the DC motor when the cassette tape is loaded.

Abstract: A circuit used in a camcorder for monitoring the recorded state of a tape during recording by simultaneous playing back of the tape comprising first and second record/playback heads mounted on a head and drum assembly for performing a record and playback of the tape, a second amplifier for amplifying the signals of the first and second heads received via switches to produce chrominance record signals, third and fourth playback only heads mounted on the head and drum assembly between the first and second heads with a given interval for exclusively performing the simultaneous playing back, first and third amplifiers connected with the third and fourth heads via switches for amplifying the video signals picked up by the third and fourth heads, third and fourth switches for respectively connecting the signals of the third and fourth heads to the first and third amplifiers, or the output signals of the first and second heads selected by first and second switches to a second amplifier, and a head switching means fo
