Abstract:
A method of producing hard disk drives of reduced size including using a one or more MEMS spindle motors, and one or more magnetic heads. Each spindle motor includes a rotor and a stator. The rotor carries a film of magnetic film, and a head is arranged to communicate data with the magnetic film. The rotors are formed by MEMS technology. Rotor elements are formed within a substrate 4, and the substrate is subsequently cut to simulate the rotor elements, and turn them into rotors.
