Flying head slider having a splay formed on a flying surface enabling a lower flying height while avoiding collision with a surface of a recording disk

摘要

A flying head slider comprises a flying surface opposed to the surface of the magnetic disk. Inner and outer rails are formed on the flying surface. Air bearing surfaces (ABS) are defined on the inner and outer rails. A magnetic head element is embedded in the outer rail at the protection layer attached to the end surface of the slider body. A splay is formed on the air bearing surface (ABS) of the outer rail. When the head slider takes off from the surface of the magnetic disk, the head slider takes a slant attitude with the protection layer nearest to the surface of the magnetic disk. The splay in the outer rail serves to avoid the protection layer from colliding with the surface of the magnetic disk even when the head slider rolls. The head slider is capable of making the magnetic head element thereon approach the surface of the magnetic disk as much as possible even if the head slider is expected to change its attitude.
