Method for distortion-free still picture reproduction with magnetic video tape

摘要

A method for distortion-free still picture reproduction from magnetic video tape slant tracks wherein the tracks are recorded and scanned without any guard band therebetween by means of two video heads which rotate in a common plane with different azimuth angles. During still picture recording, two adjacent slant tracks are continuously or repetitively scanned by two rotating video hands which have different azimuth angles with one head displaced axially by one slant track width with respect to the other. During still mode reproduction, the two adjacent slant tracks are continuously scanned by mechanically deflecting the two rotating video heads by way of plungers following a ring.
