New Design of Floppy Disk Drive Lead Screw

      Disclosed is a new design of LEAD SCREW for Floppy Disk Drive
(FDD).  This new design realizes high performance against the shock
to the FDD by changing the shape of the gap of LEAD SCREW.

      The Figure shows the gap of both the current and new design.
By shock to FDD, Follower-pin of FDD head goes up to the upper edge
of the screw.  This causes no-movement of FDD head while LEAD SCREW
is rotating.

      By virtue of this invention, the problem that FDD head moves is
resolved.
