| 1. A method of moving a slider toward a track on a disk surface in a hard disk drive, to minimize track mis-registration,
comprising the steps of:
moving said slider parallel to said disk surface toward said track, when said disk surface is flat, with an actuator arm moving
by a lever action through a principal axis with said slider aligned at a bias angle;
wherein a read-write head is encapsulated in said slider facing said rotating disk surface about a radial center in a hard
disk drive;
wherein said read-write head is communicatively coupled with said rotating disk surface to communicatively access said track;
wherein said method further comprising the step of:
radially moving said slider toward said track, when said disk surface is bent, by said lever action through said principal
axis at said bias angle causing said slider to move radially toward said track, when said disk surface is bent.
