Abstract
Magnetic recordings may be copied from one Crolyn® chromium dioxide tape to another by a simple thermal method. Surface of the copy tape is heated transiently above the Curie point (125 °C) and immediately placed in intimate contact with the master tape. At the shortest wavelength, signal level of the copy is equal to that of the master, which suffers no loss in the copy process. Thermoremanent duplicators for helical-scan videotapes are described. No plans to manufacture the thermoremanent duplicators have been made but development of the machine is continuing to establish the complete validity of copying video recordings on Crolyn tape by the thermal method.
