While this format was primarily used to store analog video, it was also used for the storage of digital audio data
This format was named after the letter U, because the course of the tape running through a playback device is shaped like the letter U
All tapes have a round red button on the back that can be removed to prevent accidental recording
"The first format in a cassette. Many early U-matics do not say U-matic on them." - J.Jay
