Magnetic head slider suspension assembly having inverted load rails

Abstract

A magnetic head slider suspension assembly for loading a head slider having an air bearing surface onto the surface of a magnetic rotating disc is shown. The magnetic head slider suspension assembly includes an elongated slider arm adapted to be attached to an arm mounting support. The elongated slider arm includes a deflectable central arm section or load beam having a support end at one end thereof which is adapted to be operatively attached to an arm mounting support and a head/slider loading end located at the other end thereof. The central arm section is generally rectangular in shape and has a predetermined width at the support end and a width which can be equal to or less than the predetermined width at the head/slider loading end. The central arm section has at least one raised load rail extending substantially perpendicular therefrom and which extends in the same direction as that of a head/slider operatively attached to the head/slider loading end. The at least one raised load rail has a length which extends from a first rail end located at about the support end to a second rail end located at about the head/slider loading end. The at least one raised load rail has a predetermined height at the second rail end and the height at the first rail end may be equal to or less than the predetermined height.
