Abstract:
A microfile comprising:a rotatably supported storage disk for storing data;a micromotor for rotating said disk and including a rotor integrated with said disk in a one-piece assembly, and also including a stator, said rotor having a plurality of magnetic rotor poles extending radially outwardly from a perimeter thereof and being circumferentially spaced apart therearound, and said stator having a plurality of magnetic stator poles circumferentially spaced apart from each other around said rotor for sequentially cooperating with respective ones of said rotor poles for rotating said rotor to rotate said disk;a selectively movable access head for selectively addressing said data on said diskeach of said stator poles comprising a magnetic core integrally wound with an electrically conducting coil for generating a magnetic flux through said core upon energizing thereof; andsaid stator pole cores and coils being integrated on a substrate and comprising deposited magnetic material and deposited conducting material, respectively, and a dielectric therebetween.
