Abstract: A method for lubricating a thin film magnetic media is disclosed wherein the magnetic media is lubricated only at the head-disc interface zone. The method comprises the steps of vaporizing the lubricant, mixing the lubricant with a carrier gas stream, and depositing a film of the lubricant on at the loading zone on the surface of the magnetic media. The lubricant film can be selectively deposited on the surface of the magnetic disc at any location and at any thickness. In one embodiment of the invention, the lubricant film forms a radial band on the surface of the magnetic disc located near the outside diameter of the magnetic disc.

Abstract: A method for producing a substantially smooth surface on a computer disk media comprises providing a substantially smooth master surface. A curable polymer dielectric composition is applied to the master surface as well as the surface of the disk to be smoothed. The master surface is then pressed onto the disk surface and the polymer is cured. The master surface is then removed and the cured polymer forms a smooth surface on the disk.

Abstract: A high-fraction, terminally nonfunctional fluoropolyether lubricant topcoat is applied to a magnetic recording medium. The topcoat provides good stiction and wear properties at a low thickness.

Abstract: An information storage system is disclosed. The information storage system includes a rigid information storage medium, at least one read/write head, an actuator, and a lubricant. The read/write head comprises a transducer for information introduction and/or retrieval from the storage medium. The actuator supports at least one read/write head for moving the transducer relative to the storage medium. The lubricant which includes a perfluoroacrylate ester polymer is disposed on the surface of the storage medium.

Abstract: A lubricant topcoat is applied to a magnetic recording medium under vacuum, thereby eliminating oxidative degradation, increasing lubricant transport properties to the disc surface, increasing uniformity and enabling control of the lubricant molecular weight distribution. Embodiments include positioning the magnetic recording medium in a deposition chamber in communication with a source chamber containing the lubricant and evacuating the chambers to subatmospheric pressure. A heater, attached to the source chamber, elevates the temperature of the lubricant within the source chamber so that the lubricant flows from the source chamber to the deposition chamber and deposits on the magnetic recording medium.

Abstract: An information storage system including a perfluoropolyether lubricant having hydroxyethyloxymethyl terminated endgroups on the surface of a rigid storage medium is provided. In the subject invention, the perfluoropolyether lubricant has the general repeat formula of: HOp(CH2—CH2O)CH2—Z—CH2(OCH2—CH2)pOH where Z is —CF2—(OC2F4)m—(CF2)n—OCF2—, p has an average value of 1.5, the ratio of m to n is approximately 1.0, and the mean molecular weight of the lubricant is in the range of approximately 2000 to 6000.

Abstract: An information storage system and lubricant comprising a fluoropolyether amide lubricant on the surface of a storage medium is provided. In general, the lubricant of the present invention is comprised of amide derivatives of fluoropolyethers having at least one hydroxyl group, preferably amide derivatives of polyalkylene glycol (PEG) and fluorinated polyalkylene glycols, and most preferably amide derivatives of per fluorinated polyethylene glycols (PF-PEG).
