Abstract
An improved lead screw drive for a disc recorder of the type including a rigid frame having a pair of spaced, parallel members. The parallel members define coaxially aligned bores. A stepper motor having an outwardly-projecting integral lead screw output shaft is supported on the frame with the lead screw extending through one of the bores to a point closely adjacent the other bore. A rotatable support is disposed in the other bore and contacts the free end of the lead screw opposite the motor. The support includes a holder having a mounting shaft extending into the bore. A conical member is rotatedly supported by the holder and contacts a seat at the free end of the lead screw. The conical member is biased against the free end of the lead screw to thereby rotatably support same.
