Duplication techniques

Even in the old days of home video, numerous techniques were used for duplication of videocassettes and replication of videodiscs.

High-speed duplication
The Sprinter was a high-speed videocassette duplication system developed by Sony in 1984. The system utilized unprecedented technology to provide consistent high quality volume VHS duplication as a cost effective alternative to conventional real time duplication. Technicolor Video Services used this system.

Thermal magnetic duplication
Another method of high-speed duplication was thermal magnetic duplication (TMD for short). Rank Video Services America used this method.
