A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape.

2013年11月7日 · With the advent of the VTR, recorded programs that could be edited replaced most live broadcasts. CBS was the first network to employ VTR technology, starting in 1956.

2-inch quadruplex videotape (also called 2" quad video tape or quadraplex) was the first practical and commercially successful analog recording video tape format. [1] . It was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. [2] .

In 1956, Ampex Corporation of Redwood City, California, introduced the first practical videotape recorder for television stations and networks to produce and time-shift broadcasts, replacing impractical "kinescope" movie film previously used to record TV.

Ampex introduced the Ampex VRX-1000 videotape recorder in 1956 which became the world's first commercially successful videotape recorder. It used the 2" Quadruplex format, using two-inch (5.1 cm) tape. Due to its US$50,000 price, the Ampex VRX-1000 could be afforded only by the television networks and the largest individual stations.

Ampex was founded in 1944 and incorporated in Califirnia in 1946. In 1947 they introduced their first audio tape recorder - the model 200A. In 1956 they introduce their first (reel to reel) video tape recorder - the VR 1000. This was a quadruplex VTR. It was the first production VTR ever sold (as opposed to earlier prototypes).

2025年3月13日 · The breakthrough in video tape recording came in the 1950s, when a team of engineers at Ampex Corporation, a small electronics company in California, developed the first practical VTR. The team was led by Charles P. Ginsburg, a brilliant engineer who had previously worked on radar systems during World War II.

In 1951, the first video tape recorder (VTR) captured live images from television cameras by converting the information into electrical impulses and saving the information onto magnetic tape.

The VCR took from many technologies in order to develop, most specifically the sound tape recorder. The same company who created the first international sound tape recorder, the Model 200, was the Ampex Corporation, and they also pioneered the development of the world’s first video tape recorder (VTR).

Ampex introduced the first commercial video tape recorder, the VRX-1000, at the 1956 National Association of Radio and Television Broadcasters Convention.
