Abstract
Abstract In a player for a disc-like record carrier with pressure pick-up, the quality of the signal picked up is dependent on the pressure of the stylus (7) on the record carrier (12). According to the invention, the optimum value of the pressure is set by a manipulated variable (Us) which is obtained from two signals of constant but different frequency (f1 and f2) picked up. <IMAGE>
