ABSTRACT:
A tape threading arrangement for a helical scan VTR with a 360 degree wrap angle has two pairs of guides. The first pair wraps the tape around a drum for 360 degrees. The second pair keeps the tape from contacting the tape on the drum and is actuated by a pair of variable length springs coupled between said guide pairs. This allows a compact structure.
