Abstract
A tape guide arrangement for a helical scan magnetic recording and playback apparatus is provided with a tape transport regulation device for causing a magnetic tape to be transported stably in a flat profile and at a constant height. A stationary lower drum coaxially and operatively associated with a rotatable upper drum, which is provided with magnetic heads, includes a stepped portion engaged by the lower edge of the tape for restricting the position of the tape with respect to height, and a tape guide portion engaged by only a limited portion of the tape adjacent to the lower end for guiding the tape along a predetermined tape transport path while maintaining the tape in a flat profile. The area over which the tape and lower drum contact and, therefore, friction therebetween is significantly reduced.
