Abstract
A video disc record system having a stylus for recovering information effects kicks which induce limited stylus translations across a disc record surface. Control circuitry responsive to a desired stylus translation are coupled to kicker means for inducing the stylus translation. Actual stylus translations are used to calibrate the kicker activation signals to minimize the kick used to induce stylus translations thereby reducing damage to the disc surface incurred during a stylus translation.
