Abstract A combined reader and recorder for both magnetic tape and magnetic cards wherein the tape and cards may be advanced in either direction during reading or recording. The apparatus comprises two spaced feed rollers extending across a card guideway and driven in either of opposite directions. Pinch rollers for holding the cards against respective feed rollers extend over one portion only of the guideway and other pinch rollers are carried by a magnetic tape magazine for guiding the tape along another portion of the rollers. A pressure pad for maintaining the cards in intimate contact with the transducer head is movable out of the way when the magnetic tape magazine is to be placed in position to process the tape.
A magnetic card transducer apparatus comprising a magnetic transducer head, a structure forming a guideway for guiding a card past said head, a feed roller for feeding said card along said guideway, a stepper motor for incrementally rotating said roller, means comprising a relatively low-frequency pulse generator for applying stepping pulses to said stepping motor; means comprising a relatively high-frequency pulse generator for applying stepping pulses to said stepping motor; a first switching device controlled by said card during movement thereof along said guideway for rendering said low-frequency pulse generator effective and said high-frequency pulse generator ineffective, and a second switching device controlled by said card during further movement of said card along said guideway for rendering said high-frequency pulse generator effective and said low-frequency pulse generator ineffective.
