Compared to Quad, Type C had a smaller size, comparative ease of operation, and slightly higher video quality. 1-inch Type C is capable of "trick-play" functions such as still, shuttle, and variable-speed playback, including slow motion. 2-inch quadruplex videotape machines lacked these capabilities, due to the segmented manner in which it recorded video tracks onto the magnetic tape. 1-inch ...
A reel-to-reel tape recorder (Sony TC-630), typical of a 1970s audiophile device.

A 14-inch reel of 2-inch quad videotape compared with a modern-day MiniDV videocassette. Both media store one hour of color video.

There is also a 35 mm width, but this variety is more similar to the motion picture stock of the same width. It is ...

D-1 or 4:2:2 D-1 (1986) was a major feat in real time, broadcast quality digital video recording. It stores uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format with 8 bits, [1] [2] along with PCM audio tracks as well as timecode on a 3/4 inch (19 mm) videocassette tape (though not to be confused with the ubiquitous 3/4-inch U-Matic/U-Matic SP cassette).
