Electronic Video Recording

Electronic Video Recording, or EVR, was a film-based video recording format developed by Hungarian-born engineer Peter Carl Goldmark at CBS Laboratories in the 1960s.

CBS announced EVR in October 1967. The 750-foot film was stored on a 7-inch-diameter (180 mm) spool in a plastic cartridge. It used a twin-track 8.75 mm film onto which video signals were transferred by electron beam recording, one monochrome track in each direction of travel.
