A high performance hard disk drive is disclosed in which a flying read/write head runs in contact or in near contact with a rotating platter. In this design there is no wear of the hard disk platter or flying head due to both head and platter being coated with an amorphous carbon that has an exceptionally low coefficient of friction in a sealed, inert gas environment. The overcoat contains carbon in the range between about 52 and 80 atomic percent and hydrogen in the range between about 20 to 48 atomic percent. There is no lubricant required in this design, which eliminates a significant cause of hard drive failure from oxidation of the lubricant, stiction and rippling of the lubricant. This contact method achieves a high areal density with no wear, within a robust, hermetically sealed environment.

High performance computer hard disk drive with a carbon overcoat and method of improving hard disk performance

Improved boron-based metal working and machining fluids. Boric acid and boron-based additives that, when mixed with certain carrier fluids, such as water, cellulose and/or cellulose derivatives, polyhydric alcohol, polyalkylene glycol, polyvinyl alcohol, starch, dextrin, in solid and/or solvated forms result in improved metalworking and machining of metallic work pieces. Fluids manufactured with boric acid or boron-based additives effectively reduce friction, prevent galling and severe wear problems on cutting and forming tools.

Metalworking and machining fluids

A durable, reliable high performance drive and method for digitizing, storing and retrieving data from a disk. In a first embodiment, at least one disk and components for spinning the disk, and digitizing, writing and reading data from the disk are covered with a 0.1 to 4 microns thick ultra low friction and wear, structurally amorphous carbon coating eliminating the need for a lubricant for sliding and rotating components. In a second embodiment the components for spinning the disk, and digitizing, writing and reading data from the disk are enclosed in a hermetically sealed housing and the housing is filled with a mixture of hydrogen and an inert gas.
