In combination with disk drive apparatus, an array of flat-coil actuator's is disclosed, with each actuator adapted to translate and position transducer means between a respective pair of stacked disk recording surfaces; each actuator comprising a number of flat-coil turns on at least one side of a planar substrate, this substrate being arranged to run between opposing magnet pole pieces along a path defined by a pair of opposed runways, with these coils being disposed in "overlapping" relation relative to one another and to respective pole pieces -thus when selected coil turns are energized the substrate may be controllably translated and positioned.
