A magnetic head slider suspension assembly for loading a head slider having 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 operatively attached to the 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 may 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 in the same direction as that of a head slider operatively attached to the head/slider loading end. The height of the load rails which extend between a first rail end and a second rail end can be uniform in height or could vary in height by a use of a continuously tapered outer edge of the spaced load rails, or by use of a stepped outer edge, or a combination thereof. A microminimonolithic having a slider body and a 'C' shaped core is operatively attached to the head/slider loading end of the magnetic head slider suspension assembly.

Combination of elongated load arm and microminimonolithic head slider

A load beam adapted for use in a head slider suspension assembly is shown. The load beam has a generally rectangular shape and includes a member for defining a support arm end and a head/slider loading end. The load beam has a torsional vibration mode characteristic which, upon said load beam being excited by a driving force, produces a fundamental mode vibration in the range of about 2000 hertz to about 4000 hertz and higher order mode vibrations above about 6000 hertz. In the preferred embodiment, the load beam has at least one load rail extending substantially perpendicular therefrom. The at least one load rail can be selected to extend from the load beam in a direction the same as or opposite to the direction in which a head/slider assembly is supported from a head/slider loading end of the load beam.

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.
