ABSTRACT:
A process and equipment is disclosed that is capable of duplicating magnetic tapes at speeds higher than 2.5 meters/second. Tape surfaces are selected that have sufficient roughness to readily permit air to bleed from between surfaces as they are held together by air pressure during the duplication process.
