Abstract

In a flexible disk drive having a lead-screw access mechanism, the head assembly carriage is mounted between a guide rod and a lead screw. The lead-screw follower is mounted tangential to the lead screw in a plane defined by the axes of the lead screw and the guide rod. If the follower is so mounted, the lead screw need not be perfectly parallel to the guide rod in that plane in order to avoid recording head indexing error. Fig. 1 is a schematic representation of a head carriage moved along guide rod 12 by lead screw 14 and lead-screw follower 16. Carriage 10 is held in position in a plane parallel to the plane through the axes of the lead screw and the guide rod by guides 18 and guide 20. Guide rod 12 passes through apertures in guides 18, while lead screw 14 passes through an aperture in guide 20.
