- Abstract
- Broadcast-quality copies of quadruplex transverse videotape recordings have been produced in the laboratory by the contact-duplication process. The program material is recorded on high-coercivity tape in a mirror-image format. The oxide surfaces of this master tape and a conventional tape are pressed together and are passed through a transfer field to effect the duplication of the video material, while the audio, cue and control tracks are played back and re-recorded on the slave. Topics discussed include choices of production techniques for obtaining the high-coercivity master recording, comparison of the two basic configurations for a duplicating system, the copy rates obtainable with each of these configurations, and the major parameters to be considered in selecting a copy tape as well as a high-coercivity master. Performance characteristics which can be expected on distribution copies made by the contact duplication technique are presented.
