摘要： A hard protective material and method for forming the medium having the formula C.sub.x N.sub.y. The medium may be formed as a protective film on a magnetic recording disk in a sputtering apparatus such as a magnetron apparatus. The amount of nitrogen in the film may be affected by controlling the collisions of the sputtered material between the target and deposition substrate by controlling the bombardment of the substrate by electrons. The films exhibit properties indicative of a textured morphology on a nanoscale which enhances the retention of lubricant overcoats.

摘要： A breather filter cartridge in a data storage device contains a filtration media, such as packed granular carbon, in a chamber. The cartridge incorporates a gas diffusion path that traverses through the breather filter casing, interfacing with the chamber along a tubular sidewall and allowing the thickness of the filter top end to be reduced. This permits additional filter media to be packed into the same breather filter height. Alternatively, the same amount of filtration media can accordingly be packed into a thinner breather filter. The top end may also include an outward extending flange, with the chamber extending completely through the flange. A thin film seals the media above the flange, allowing for even more filter media to be packed into a breather filter of identical height.

摘要： Amphiphilic compound having one of the following structures:(X--T).sub.n --A--Y.sub.m and (X-T).sub.n --R--(T--A).sub.nwherein X is a fluorocarbon terminal group, T is a polar linking group, A is a nucleus other than saturated lower aliphatic, Y is a polar nonlinking group, R is a saturated or unsaturated, substituted or unsubstituted, straight or branched lower aliphatic group, n is at least one, and the sum of n and m is at least two. Such compounds are useful as lubricants for magnetic media. Also, a lubricated magnetic medium comprising a planar, polar surface covered with a monolayer comprising a compound having the structure described above, except that A can also be a saturated lower aliphatic group.

摘要： A data storage system with a breather filter is provided. The enclosure of the data storage system has a first end and a second end and includes a least one disc adapted to rotate in a rotational direction. The second end further includes a first corner and a second corner wherein the second corner is downstream from the first corner relative the rotational direction of the disc. A recirculation filter is spaced radially outward from the disc and disposed between the disc's outer diameter and either the first corner or the second corner. The breather filter is disposed radially outward from the disc and downstream from the recirculation filter relative to the rotation of the disc in a negative air pressure region.

摘要： An apparatus for mitigating particle and aerosol contaminants from an internal environment of a data storage device is disclosed. The apparatus includes a base, a breather diffusion path formed in the base, a re-circulating filter channel adjacent the base, and an absorption filter chamber adjacent the re-circulating filter channel and communicating with the breather diffusion path. A breather filter removes particulates from air migrating through the diffusion path. The length and diameter of the diffusion path precludes transfer of humidity from the external environment of the data storage device to the internal environment of the data storage device. A re-circulating filter spans the re-circulating filter channel and removes particulates from airstreams passing through the re-circulating filter channel, and a substantially carbon based absorption filter extracts corrosive gases and organic vapors from the internal environment of the data storage device.
