ABSTRACT:
In a rotary head drum device for use in a video tape recorder or the like, a motor is provided between a rotating drum and a fixed drum. A drum base has at least three supporting surfaces for supporting the head drum. The supporting surfaces are formed at positions substantially equally spaced from a center of a rotating shaft fixed to the rotating drum and substantially equally spaced from each other. A single screw for fixing the fixed drum to the drum base is threaded into the fixed drum in the vicinity of the rotating shaft. With this construction, quality can be improved, and cost can be reduced.
