ABSTRACT:
A head drum ground system for use with a VCR comprises an electrical coupler which is located and arranged in an inner space of the head drum assembly so that a rotary drum is electrically connected with a stationary drum within the VCR. As a result, static electricity occurring on the surface of the rotary drum is transmitted to a deck supporting the stationary drum, through a boss member, the electrical coupler, an outer ring of a bearing, and the stationary drum, in that order.
