Thin data storage device having a flexible recordable disk and recording heads arranged on both sides of the disk

A thin data storage device comprising;

• a housing that has a top and a bottom cover;
• a printed circuit board having electronic integrated circuits mounted thereon, the circuit board being attached to one of the covers of the housing;
• a rotatable spindle formed about a cylindrical shaft, the spindle being rotatable by rotation means;
• a magnet structure rigidly mounted to a flange attached to the spindle, the magnet structure facing inward towards the spindle shaft;
• a stator comprising plates of soft magnetic material having coils wrapped on legs of the stator, the stator rigidly attached to the printed circuit board and oriented such that an outer face of the stator is in close proximity to the magnetic structure on the spindle;
• at least one flexible recordable disk non-removably mounted to the spindle in a mounting plane to rotate therewith;
• at least a top and a bottom recording head arranged on both sides of the disk to write and read information to and from the disk;
• a woven liner attached to the top of the printed circuit board over the electronic integrated circuits separating the printed circuit assembly from the environment containing the recording heads and the disk;
• a rotor arranged on a second shaft, the rotor being located at a point spatially displaced from the first shaft and connected to one of the covers, the rotor being rotatable by a second rotation means configured to allow the rotor to move in a plane parallel to a recording surface of the disk;
• a coil of wire attached to one side of the rotor and displaced in a magnetic field developed between a magnet structure mounted to a first soft magnetic plate attached to the bottom cover and a second soft magnetic plate attached to the top cover forming an air gap in which the coil can rotate freely;
• and
• a flexible printed circuit cable attached to the printed circuit board and to the rotor to provide a path for electrical servo control and recording signals between the rotor coil, recording heads and the printed circuit board.
