Details
Betamax (sometimes called Beta) is a home videocassette tape recording format developed by Sony, released on May 10, 1975. The cassettes contain 1/2-inch (12.7mm)-wide videotape in a design similar to the earlier, professional 3/4-inch (19.05mm) U-matic format. The format is generally considered obsolete, though it is still used in specialist applications by a small minority of people. Like the rival videotape format VHS (introduced in September 1976[1] by JVC), Betamax had no guard band and used azimuth recording to reduce crosstalk. According to Sony's own history webpages, the name came from a double meaning: beta being the Japanese word used to describe the way signals were recorded onto the tape, and from the fact that when the tape ran through the transport, it looked like the Greek letter beta ( ). The suffix -max came from "maximum", to suggest greatness. Sanyo marketed a version as Betacord, but this was also referred to casually as "Beta".
