EIAJ-1

From Wikipedia, the free encyclopedia

EIAJ-1, developed by the Electronic Industries Association of Japan (in conjunction with several Japanese electronics manufacturers) in 1969, was the first standardized format for industrial/non-broadcast videotape recorders (VTRs). It was developed in response to most non-broadcast industrial VTRs on the market at the time not using an industry-standard format, relying on proprietary formats exclusive to the make (and sometimes model) of VTR. As a result, tapes recorded on one make and/or model of VTR could only be interchanged with the same, hampering compatibility. EIAJ-1 did away with all of this, giving those manufacturers a standardized format interchangeable with almost all the VTRs that they manufactured.

The EIAJ-1 standard paved the way for non-professional video recording technology to become more affordable and widespread, with many businesses, schools, government agencies, hospitals, and the like to immediately adopt the format in the early 70s. Some of the first public access television stations that went on the air in that same era also used EIAJ-1 extensively, due to its portability, cost, and versatility.

The format offered black & white (and later colour) video recording and playback on 1/2" tape on a 7"-diameter open reel, with portable units using smaller 5"-diameter reels. Another version, EIAJ-2, was released that used a single-reel cartridge (with the take-up reel being built-in to the VTR) instead of an open reel (otherwise it was the same as EIAJ-1).
