<p>Case No. 1-751120-TSO INVENTOR: Robert H. Trenkamp TITLE: DATA TRANSDUCER An optical and magnetic data transducer is provided comprising a magnetic reluctance aperture which is split into two sections with an optical reading aperture disposed generally therebetween. This reduces timing errors between the optical and magnetic output signals indicative of the spacial relation of the optical and magnetic data element boundaries, such errors being due to variations in temperature and skewing.</p> |
