Integrated Disk File Module and memory storage system

A completely integrated and self contained disk file module enclosed within its own sealed container comprising:

• a. a horizontal baseplate having a plurality of vertical flanges;
• b. a support frame housing a vertical spindle, said support frame mounted centrally on said horizontal baseplate;
• c. a motor comprising a stator mounted on said support frame and a rotor unit mounted on said spindle for rotation around said stator, said rotor unit supporting a magnetic disk;
• d. a magnetic disk having a central opening, said motor being integral with said disk by means of said opening;
• e. an actuator assembly mounted on one of said vertical flanges, said actuator assembly including:
• e-1. a voice-coil supporting upper and lower head-support arms;
• e-2. said upper and lower head support arms supporting a plurality of upper and lower transducer heads adjacent both planar surfaces of said magnetic disk;
• e-3. means to control the position of said transducer means in relation to the plane surfaces of said magnetic disk, said means including:
• e-3-a. a rotary solenoid mounted adjacent one end of said voice-coil;
• e-3-b. a rotatable cam mounted at the opposite end of said voice-coil;
• e-3-c. a central rotatable rod connecting said rotary solenoid and said rotatable cam;
• e-3-d. upper and lower pivot pins, located opposite from said solenoid-end of said voice-coil, said pivot pins rotatably supporting said upper and lower head-support arms, whereby activation of said rotary solenoid will rotate said cam to cause clockwise rotation of said upper head-support arm and to cause counter-clockwise rotation of said lower head-support arm to respectively move said upper and lower transducing heads out of and into transducing position with respect to the surfaces of said magnetic disk.
