ABSTRACT:
A magnetic disk drive mechanism has a magnetic disk, a magnetic disk drive motor for rotating the magnetic disk, a magnetic head for recording and reproducing information on and from the magnetic disk, and a chassis defining a hermetically sealed chamber which houses the magnetic disk, the magnetic disk drive motor, and the magnetic head therein. Printed wire patterns are disposed on a surface of a flat stator base of the motor which faces into the hermetically sealed chamber, the printed wire patterns having terminals extending out of the hermetically sealed chamber. An O-ring is interposed between the chassis and the stator base, for hermetically sealing the terminals from the hermetically sealed chamber.
