Abstract
A device for marking an information carrying medium has an arm with a pointed tip adapted to engage the medium. The arm is spring biased for movement in one direction, and a solenoid structure is provided for moving the arm in the other direction. A land surface cooperates with the arm to form an air pressure damping arrangement to damp movements of the arm in a direction away from the information carrying medium.
