Abstract

In one embodiment, the invention provides a thin data storage device comprising a housing that has a top and a bottom cover and a printed circuit board having electronic integrated circuits mounted thereon. A rotatable spindle is formed about a cylindrical shaft and is rotatable by rotation means. A magnet structure is rigidly mounted to a flange attached to the spindle. A stator is attached to the circuit board and comprises plates of soft magnetic material having coils wrapped on legs of the stator. At least one flexible recordable disk is non-removably mounted to the spindle. A top and a bottom recording head is arranged on both sides of the disk. A woven liner is attached to the top of the circuit board over the integrated circuits. A rotor is arranged on a second shaft at a point displaced from the first shaft. The rotor is rotatable by a second rotation means configured to allow the rotor to move relative to the disk. A coil of wire is attached to one side of the rotor and is displaced in a magnetic field developed between a magnet structure mounted to a first soft magnetic plate that is attached to the bottom cover and a second soft magnetic plate that is attached to the top cover. A flexible printed circuit cable is attached to the circuit board and the rotor to provide a path for electrical servo control and recording signals between the rotor coil, recording heads and the circuit board.
