ABSTRACT:
There has been provided, in accordance with the present invention, a cathode ray tube recording system which includes means for superimposing grid lines on the resulting record. The grid lines so-recorded for each complete record are not shifted. At the beginning of each new record, however, a randomly selected bias is applied to the grid line positioning circuit whereby the grid lines are started on a fresh phosphor position for each subsequent recording but selected on a random basis.
