Type C videotape

1 inch Type C (designated Type C by SMPTE) is a professional reel-to-reel analog recording helical scan videotape format co-developed and introduced by Ampex and Sony in 1976. It became the replacement in the professional video and broadcast television industries for the then-incumbent 2 inch Quadruplex videotape (2 inch Quad for short) open-reel format, due to the smaller size, comparative ease of operation (vs. 2 inch) and slightly higher video quality of 1 inch type C video tape recorder (VTR). 1 inch type C required less maintenance downtime than Quadruplex videotape, and did not require time base correction to produce a stable video signal.
