- Betamax abstract "Betamax (also called Beta, and referred to as such in the logo) is a consumer-level analog videocassette magnetic tape recording format developed by Sony, released in Japan on May 10, 1975. The cassettes contain .50 in (12.7 mm)-wide videotape in a design similar to the earlier, professional .75 in (19 mm) wide, U-matic format. The format is virtually obsolete, though an updated variant of the format, Betacam, is still used by the television industry.Like the rival videotape format VHS (introduced in Japan by JVC in October 1976 and in the United States by RCA in August 1977), 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 (β). The suffix -max, from the word "maximum", was added to suggest greatness.In 1977, Sony came out with the first long play Betamax VCR, the SL-8200. This VCR had two recording speeds: normal, and the newer half speed. This provided two hours recording time onthe L-500 Beta videocassette. The SL-8200 was to compete against the VHS VCRs thathad 2 or 4 hours of recording time.Sanyo marketed a version as Betacord, but this was also referred to casually as "Beta". In addition to Sony and Sanyo, Beta-format video recorders were also sold by Toshiba, Pioneer, Murphy, Aiwa, and NEC; the Zenith Electronics Corporation and WEGA Corporations contracted with Sony to produce VCRs for their product lines. Department stores like Sears (in the United States and Canada) and Quelle (Germany) sold Beta-format VCRs under their house brands, as did the RadioShack chain of electronic stores. Betamax and VHS competed in a fierce format war, which saw VHS come out on top in most markets.".
