- Ampex_2_inch_helical_VTR abstract "From 1963 to 1970, Ampex manufactured several models of VTR 2 inch helical VTRs, capable of recording and playing back analog black & white video. Recording employed non-segmented helical scanning, with one wrap of the tape around the video head drum being a little more than 180 degrees, using two video heads. One video drum rotation time was two fields of video. The units had two audio tracks recorded on the top edge of the tape, with a control track recorded on the tape's bottom edge. The 2" wide video tape used was one mil (0.001 in or 0.0254mm) thick. The VTRs were mostly used by industrial companies, educational institutions, and a few for in-flight entertainment.The capstan tape speed is 3.7 inches per second, which provided a long record time of up to 5 five hours on large reels. The units were 100% solid state. The Ampex 2 inch helical VTRs were popular, as they were priced much less that the 2 inch quadruplex videotape recorders used in the broadcast television industry at the time.".
