Abstract: Honeycomb fabricated of non-crosslinked polymer is prepared by impregnating a fiber web with a linear prepolymer which is soluble in an organic solvent, and which is readily converted by thermal curing in the absence of a crosslinking agent to an insoluble form with a glass transition temperature exceeding 200.degree. C., preferably exceeding 250.degree. C. The preferred prepolymer is the product of diaminodiphenylsulfone and trimellitic anhydride, and forms a poly(amide-imide) upon cure. A process for forming the impregnated honeycomb is also disclosed, which involves impregnating ribbons or sheets, forming them into stacks bonded together at node lines, expanding the stacks into honeycomb structures, and heat soaking the expanded structures to cure the resin and stabilize the structure.

Abstract: 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.

Abstract: A microminimonolithic magnetic head slider adapted for use with a magnetic head flying on an air cushion over a magnetic media for recording and reproducing tracks of information is shown. The slider includes an aerodynamic surface which has a pair of spaced, parallel load rails which are adapted to fly over the moving magnetic media. The load rails have an air bearing surface formed thereon, and each air bearing surface has a width which is greater than a track width of information on the magnetic media. Also, the aerodynamic surface has, located between the pair of spaced, parallel load rails, a wedged-shaped central rail having an apex which defines an air bearing surface having a width which is less than the width of the air bearing surface on the load rails. The slider includes a transverse slot which is spaced from and extends substantially perpendicular to the pair of spaced, parallel load rails and the central rail and a pair of spaced, vertically extending slots.
