In 1953, Norikazu Sawazaki developed a prototype helical scan video tape recorder. [10] BCE demonstrated a color system in February 1955 using a longitudinal recording on half-inch (1.27 cm) tape.

The number of video tape recorders continued to increase during the late 1960s, leading to the EIAJ-1 standard for 1 ⁄ 2-inch tape on a 7 inch reel. The follow-up EIAJ-2 built the take-up reel into the recorder body. In September 1971, Sony introduced the U-matic format, aimed at professional users, which replaced the open reels with a cassette.
When EIAJ-1 was standardized, no videocassette recorders had yet been introduced. One of the main drawbacks to the format was the need to carefully thread the end of the tape around the head drum, through a gap between the capstan and pinch roller, and around a variety of guides and tensioners.

It was capable of 350 lines.
