An electronic transducer array and transfer device and method which provides for activation of selected transducers at selected times. In one application, the device performs data transfer by a combination of suitably interconnected submillimeter transducers (4) capable of sensing and/or actuating microscopic data-storage cells, and electronic switching (402, 602, 702) to activate selected individual transducers. One embodiment of the invention provides for magnetic transducers for reading (304) and writing (302) on a magnetic medium (8). Another embodiment of the invention provides tunneling electron transducers (10) arranged in an array.
