ABSTRACT:
A wear compensating transducer is provided for reading optical and magnetic data from documents comprising a magnetic read head with a group of optical fibers passing through the reluctance gap and with the fiber ends disposed for wiping engagement with documents as they are read. The fiber ends define an optical reading aperture which remains substantially constant as the fiber ends wear with the contact surface of the magnetic head.
