Abstract
Abstract An apparatus for handling a vertically oriented record card carrying a magnetic stripe having an ''''instructor'''' track and a ''''student'''' track, for transport of the card across a transducer head. A transducer head blocking lever is included which yields in one direction to permit normal movement of the card along a guide track across the transducer head, but prevents engagement of the card with the head when the card is attempted to be inserted into the track in a direction perpendicular to the normal path of movement of the card along the track. The apparatus also is adapted to selectively preclude accidental recording by a student upon the instructor track of the record card. Accordingly, the apparatus is provided with an interlock between the transducer head and the recording actuator to permit recording on the ''''student'''' track but to prevent recording on the record card when the transducer head is positioned at the ''''instructor'''' track, and an override feature serving to disable the interlock.
