Abstract

A magnetic stripe reader adapted for reading stripes on media of different thicknesses includes a magnetic head with a position which adjusts to the medium thickness. A head stop arrangement permits a simple technique for setting the maximum head position to be used. A special tool is inserted in a bracket fixed to a reader wear plate. A bracket is positioned to mate with a head which is displaced its maximum distance from an opposing rail. A conducting shim is placed between the head and the opposing rail and a current flowing through an electric circuit including the head and the shim is measured by an ohmmeter in the circuit. The bracket rotates about a pin to adjust the position of the head until continuity of the circuit is broken. The bracket then is secured into position.
