A guide drum assembly comprises a rotary drum mounted with at least one rotary magnetic head, a rotary shaft rigidly fixed to the rotary drum so that the rotary drum rotates when the rotary shaft rotates, a motor having a stator and a rotor which generates a torque for driving the rotary shaft, and a resilient member having both viscosity and resiliency for resiliently coupling the rotor to the rotary shaft. The resilient member absorbs vibrations in a circumferential direction of the rotor.

Guide drum assembly with built-in motor having floating rotor

A head drum construction for use in a magnetic recording and reproducing apparatus such as a VTR apparatus comprises a rotatable drum having first and second axially opposite surfaces, a recording magnetic transducer such as a recording magnetic head mounted on the rotatable drum for recording information signals on a magnetic tape, a playback monitoring magnetic transducer such as a reproducing magnetic head mounted on the rotatable drum for reproducing, with a time delay, the information signals recorded on the magnetic tape by the recording magnetic transducer, a first signal transmission path connected to the recording magnetic transducer and disposed on the first surface, and a second signal transmission path connected to the playback monitoring magnetic transducer and disposed on the second surface.
