A drive follower assembly for a disc recorder of the type including a frame supporting a lead screw and a guide rod positioned in vertically spaced, parallel relation to the load screw is disclosed. The drive follower includes a one-piece carriage defining a longitudinal bore. A first, hollow, cylindrical, internally threaded follower is disposed within the bore and held against rotation and longitudinal movement relative to the body. A second, internally threaded adjustment member is loosely held within the bore and engaged by the lead screw. A coil spring is positioned between the follower member and the adjustment member to provide a snug fit on the lead screw and prevent decoupling. Provision is made for holding the adjustment member against rotation relative to the body yet permitting relative rotation for adjusting the initial preload of the spring.
