A fabrication method for a thallium-doped GRIN lens composed of a simplified glass composition is described. The composition is composed of silicon, oxygen, boron, zinc, potassium, sodium, and thallium. The method is comprised of preparing a cylindrical preform, annealing the cylindrical preform, removing contaminants from preform thereafter extruded to form a glass rod, exposing the glass rod to an alkali salt bath, and chemically milling the glass rod within an acid bath. Method and composition produce colorless lenses with a refractive index from 1.5900 to 1.7810, an insertion loss no greater than 0.05 dB, and a chromatic transmittance greater than 90 percent.

A magnetic recording medium including a lubricant topcoat having increased bonding to the medium surface comprises an amphiphilic lubricant molecule having a hydrophilic central portion including a plurality of polar functional groups bound to the medium surface and a pair hydrophobic fluoroalkyl ether or perfluoroalkylether end portions at respective ends of the hydrophilic central portion and extending away from the medium surface.

A thin-film magnetic recording disc for use with a read/write head in a disc drive includes a substrate, a magnetic recording film disposed over the substrate, and a protective overcoat on the recording film. The recording disc has an outer layer that includes a solid fluorocarbon and a perfluoropolyether (PFPE) oil. The disc can be used as a data storage media for a digital computer and, in particular, with a read/write head in a disc drive. The addition of the fluorocarbon layer can improve the tribology of the disc, thereby reducing wear and improving the long-term performance of the magnetic disc.
