Abstract
A reader/writer device for flexible data cards is disclosed. The device includes a pair of pivotal arms which are adapted to receive a data card in a flat position and then to bend the card into a substantially cylindrical shape. A rotatable transducer is located so that its axis of rotation coincides with the axis of the cylindrically bent data card. The recording medium on the data card faces the transducer such that the transducer scans in lines which are parallel to the data tracks set forth on recording medium. High speed data reading and writing may be accomplished in this manner.
