ABSTRACT:
In a control system, a shock resulting in an error is detected. The detection of the shock initiates compensation to reduce the error. The compensation depends on corrective data contained in a memory of the player. The error while being reduced by the compensation is measured, and the corrective data is updated depending on the measured error.
