Abstract: A document card positioning mechanism for accurately locating a moving document card at a predetermined station in its path of movement including a card stop movable into engagement with a stationary plate defining one boundary of the path of card movement with the stop having a slanted surface on which the leading edge of the card abuts, and a pivoted wedge element movable out of the path of card movement by the card as it passes along said path toward said stop and movable back into the path of card travel so as to wedge against the trailing edge of the card and hold it forcefully in engagement with the slanted stop surface.

Abstract: TRANSDUCERS WITH TAPERED EDGE PROFILES AND ASSEMBLY THEREOF An assembly of a pair of magnetic transducers held in substantial contact with a flexible magnetic disk wherein each transducer has a pair of disk contacting lands broadening in contour toward the trailing end of the transducer and tapering in contour toward the leading end of the transducer, with the leading and side edges of each land being gradually blended into the surrounding active surface of the transducer and with the trailing edge of the land being sharp. A first one of the lands of each transducer has the read/write magnetic gap in it, and this land is located opposite the land of the other transducer not having the read/write gap in it which is wider than the first land. The centers of the opposite lands are in alignment, and the centers are measured on a plane passing through the read/write gaps of the transducers. R0978-014

Abstract: A machine for writing information on and reading information from a relatively wide magnetic tape including a carousel for receiving a plurality of cartridges holding such tape with the cartridges being disposed with their axes parallel with the axis of rotation of the carousel, a plunger for latching onto a cartridge in the carousel and moving the cartridge out of the carousel into a tape unwinding position, motor mechanism for unwinding the tape in this position and moving it across a bed carrying a rotatable magneitc read/write disk substantially coextensive with the face of the bed on which the tape travels, a takeup spool for receiving the tape passing across the bed and including a swingable arm for causing the tape to start winding on the spool, and a relatively slowly moving mandrel and a pressure roll cooperating with the mandrel for subsequently moving the tape across the bed so that the disk may have a magnetic reading or writing action with respect to the tape.
