PROBLEM TO BE SOLVED: To provide a rotating magnetic head drum that can be easily disassembled while maintaining the precision of the components after assembly. SOLUTION: The rotating magnetic head has a stationary center shaft whose one end is pressed into the center hole of the lower stationary drum, a bearing housing secured free to turn at the center of the stationary shaft, a rotating drum secured to the lower side of the bearing housing to turn together with the bearing housing, a magnetic head attached to the lower side of the rotating drum, a rotating transformer attached to the upper surface of the rotating drum, an upper stationary drum attached to the upper end of the stationary center shaft, and a rotating transformer attached to the lower surface of the upper stationary drum. The bearing housing and the rotating drum are assembled together by fastening the male thread formed around the upper cylinder of the bearing housing and a female thread formed inside the center through hole of the rotating drum.
