Disclosed is a rotary head drum for a VCR having an improved structure. A cylindrical lower drum and an upper drum installed on the lower drum and rotatably supported by the lower drum, are included. At least two video heads are provided at the outer lower portion of the upper drum for recording or playing a video signal onto or from a magnetic tape. Also, a lower rotary transducer is formed in an upper potion of the lower drum. An upper rotary transducer is positioned on the lower rotary transducer for transmitting an applied signal from the video head to the lower rotary transducer. A stator is positioned on the upper rotary transducer. The stator is transformed into an electromagnet according to an application of current. A ring-shaped magnet is provided in the upper drum at the same height as the stator. A circular magnet is formed above the stator and in the upper drum. Since the drum shaft insertion process is eliminated, the manufacturing of the head drum is advantageous. In addition, the noise generated during the operation of the head drum is reduced.
