We all know vedio casset recorder commonly known as VCR.The world's first practical videotape recorder was released in 1956. It was as large as a dining room table and cost a cool $50G. The Ampex VRX-1000 featured an incredibly modern-sounding model number, too.
The VRX-1000 set off a storm when it was demonstrated on April 14, 1956 at the National Association of Radio and Television Broadcasters Convention, sending RCA and all the other VTR developers back to the drawing boards. The VRX-1000 was renamed the Mark IV and sold briskly at $50,000. Ampex dominated the broadcast VTR business for a number of years to come. The fourth person from the left in the above design team group photo is Ray Dolby, later of Dolby Laboratories fame.
Ampex discovered that the secret to recording video on tape was to use a rotating head. This enabled them to fit 90 minutes onto a single reel, making the VTR practical for TV broadcast use. The tape ran past the head at 15 inches per second, so those reels must have been huge! They obviously hit on the right approach: Modern VHS and dv recorders still use a rotating head mechanism.
