Tri-pad air bearing head slider having leading edge and trailing edge of air bearing side pads tapered to minimize takeoff and landing velocity and time

摘要

A novel tri-pad head slider includes a slider body having an air bearing surface and leading and trailing edges with first and second sides extending from the leading edge to the trailing edge; first and second side pads formed on the air bearing surface of the slider body, and disposed at respective first and second sides of said slider body to extend from the leading edge toward the trailing edge of the slider body; and a third pad disposed at the rear center of said slider body at the trailing edge to extend from the trailing edge toward the leading edge of the slider body. Each of the first and second side pads has an opposite tapered portion integrally formed therein and tapered toward the leading and trailing edges of the slider body at predetermined angles for introducing air flow caused by rotation of a disk and reduction of air pressure generated when the slider head takes off from and lands on the disk.
