Abstract
A stabilizer is shown with a special leading edge for enhancing the magnetic interface between a magnetic head and a rapidly moving pliable magnetic disk. The stabilizer includes a stabilizing block with an opening through which the head protrudes for engagement with the disk. A flat, circumferential air bearing surface surrounds the opening adjacent the disk for generating coupling forces that deform the disk out of its nominal plane and into intimate contact with a transducing gap on the head. The leading edge of the stabilizer has a generally arcuate surface that abruptly meets the air bearing surface at a non-tangential transition. The transition appears to the disk as a fulcrum, imparting a torque to the disk that contributes to the coupling forces and ensures 'capture', that is, interface, even with disks having troublesome irregularities such as warps.
