Abstract: A magnetic disk file machine has a pair of opposed transducers, one transducer 150 of which is movable to engage a magnetic disk rotatably disposed in a magnetic diskette assembly in the machine against the other, a pressure plate opposed to a platen portion for holding the disk in a proper data transferring plane, and a manually operable knob 242 mechanically connected with the movable transducer and with the pressure plate for moving these parts between original positions, which are widely separated from the opposed parts to allow positioning of a magnetic diskette in the machine, and intermediate positions in which the spacing is less. The machine includes a solenoid mechanically connected with the movable transducer and with the pressure plate for moving these parts from their intermediate positions to final positions in which the movable transducer engages the disk and in which the pressure plate grips the diskette and holds the disk in a proper data transferring plane. The mechanical connections from the knob to the pressure plate and to the movable transducer include an oscillatable shaft 240 connected with the knob and having an eccentric portion 241 effective for moving these parts between original and intermediate positions. The solenoid is positioned on the other side of the machine to the oscillatable shaft, and a flexible cable 270 connected the solenoid with mechanism on the shaft side of the machine for moving the pressure plate and movable transducer between intermediate and final positions.
