Abstract
Approaches for a head slider for use within a hard-disk drive. The head slider comprises an air bearing surface (ABS) and an electromagnetic transducer disposed at an air outflow end of the air bearing surface. The air bearing surface comprises an inner (ID) side rail proximate the inner diameter side and an outer (OD) side rail proximate the outer diameter side. The ID side rail is longer in length than the OD side rail. The physical dimensions of the ID side rail have a geometry that reduces a contact force between the head and the magnetic-recording disk when the head experiences a positive roll static attitude (RSA). The physical dimensions of the OD side rail have a geometry that reduces contact force between the head and the magnetic-recording disk when the head experiences a negative RSA.
