Abstract: The magnetic properties of a cobalt based, thin film, magnetic recording layer are controlled, independent of controlling the process for depositing the magnetic layer itself, by the introduction of process compatible dopant gases into an argon atmosphere during the vacuum deposition (i.e. a sputtering process or an evaporation process) of a chromium based underlayer upon which the magnetic layer is subsequently deposited. The same or a different dopant may also be introduced into the magnetic layer. The process compatible dopant gases described contain oxygen, nitrogen and/or carbon, and mixtures thereof, and include the group purified air, oxygen, nitrogen, a mixture of oxygen and nitrogen carbon monoxide, carbon dioxide, methane and water vapor.

Abstract: A lubricant film for a thin-film disk comprises a monolayer of fixed lubricant bonded to the surface of the thin-film disk and a mobile lubricant in contact with the layer of fixed lubricant. The monolayer of lubricant film is applied to the thin-film in a method comprising applying a lubricant composition to the surface of a thin-film disk, then heating the thin-film disk at a sufficient temperature for a sufficient time to bond or fix a portion of the lubricant composition to the disk; to evaporate a portion of the lubricant composition from the surface of the disk; and to dispose a portion of the lubricant composition as a mobile lubricant in contact with the fixed lubricant.

Abstract: THE MAGNETIC PROPERTIES OF A COBALT BASED, THIN FILM, MAGNETIC RECORDING LAYER ARE CONTROLLED, INDEPENDENT OF CONTROLLING THE PROCESS FOR DEPOSITING THE MAGNETIC LAYER ITSELF, BY THE INTRODUCTION OF PROCESS COMPATIBLE DOPANT GASES INTO AN ARGON ATMOSPHERE DURING THE VACUUM DEPOSITION (I.E. A SPUTTERING PROCESS OR AN EVAPORATION PROCESS) OF A CHROMIUM BASED UPDERLAYER UPON WHICH THE MAGNETIC LAYER IS SUBSEQUENTLY DEPOSITED. THE SAME OR A DIFFERENT DOPANT MAY ALSO BE INTRODUCED INTO THE MAGNETIC LAYER. THE PROCESS COMPATIBLE DOPANT GASES DESCRIBED CONTAIN OXYGEN, NITROGEN AND/OR CARBON, AND MIXTURES THEREOF, AND INCLUDE THE GROUP PURIFIED AIR, OXYGEN, NITROGEN, A MIXTURE OF OXYGEN AND NITROGEN, CARBON MONOXIDE, CARBON DIOXIDE, METHANE AND WATER VAPOR.( FIG 1 )
