ABSTRACT:
A rotary head helical scan tape record and/or reproduce apparatus has an upper rotatable cylindrical drum tape guide section and a stationary lower cylindrical drum tape guide section that includes a narrow upper ridge which is displaced radially from the axis of the stationary cylindrical drum tape guide section in a direction towards the location where the rotary head ends the scan of the tape. Magnetic tape is transported in a helical path from the lower stationary drum guide section, over the radially displaced upper ridge to the upper rotatable drum guide section, which carries the record and/or reproduce heads that transfer signals to and from the tape.
