This invention relates to a rotating magnetic head drum of a magnetic recording/reproducing device, and particularly relates to a transformer mounting structure suitable for recording and reproducing two input/output signals. Some devices require a transmission path, and some use a pair of planar rotary transformers and a pair of cylindrical rotary transformers as the transmission means. For example, when simultaneous monitoring is performed during recording, the recording signal and the reproduction signal are transmitted through separate rotary transformers to prevent crosstalk between the two signals.

In order to replace parts a and 1b, the rotating transformer rotor 6 is attached to the rotating drum 2 with screws 10, and has a removable structure.
As a result, the facing area of the rotary transformer was limited, and it was not possible to install a rotary transformer that transmitted a large number of signals.

In order to achieve the above object, the present invention provides a rotating magnetic head drum equipped with a pair of planar rotating transformers and a pair of cylindrical rotating transformers, in which a cylindrical rotating member is provided, and an inner diameter surface of the member is provided with a cylindrical rotating member. After fixing the rotor of the cylindrical rotary transformer to the top and the rotor of the planar rotary transformer to the bottom, these members were screwed to the rotary drum.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In FIG. 2, a planar rotating transformer rotor 21 is bonded to one end surface of a member 19, a cylindrical rotating transformer 7 is bonded to a radial surface of the member 19, and one end of the member 19 is attached to a screw 20.

According to the present invention, since the facing area of the planar opposed rotary transformer can be expanded, it is most suitable for a multi-functional rotary magnetic head drum equipped with a large number of heads, and it is also possible to integrate two rotary transformer rotors into one unit. Therefore, the assembly process can be simplified and the process can be shortened. Furthermore, since the surface of the rotating drum is finished with a mirror-like finish, it is easily scratched, but by shortening the process, the occurrence of defects can be reduced.
