APPARATUS FOR LATERALLY CORRECTING THE POSITION OF THE BLUE BEAM IN A CRT

A plurality of magnetic rubber disks each axially magnetized to form a first magnet in a first portion and a second magnet in a second portion diametrically opposed to the first portion and with the poles positioned oppositely. The disks are axially aligned on a common spindle, with adjacent poles being similar, and the spindle is rotatably mounted adjacent the neck of a multi-beam cathode ray tube. The magnetized disks are mounted to produce variable amounts of movement, in either direction, of the blue beam while producing lateral movement of the other two beams in the opposite direction.
