ABSTRACT:
An imaging head for use in a spark-discharge recording apparatus, including a tracking system for monitoring and maintaining the head a fixed distance away from the surface of a recording blank. The tracking system preferably measures the distance between the head and the surface of the blank using a gas source oriented toward the blank's surface and a pressure sensor for measuring the pressure of the gas reflected therefrom. The signal produced by the pressure sensor indicates the size of the gap. The pressue sensor is coupled to a servo system that alters the position of the head to maintain a preselected gap distance.
