20090274835 | DIFFUSER/SHUTTER DESIGN FOR VAPOR PHASE LUBRICATION PROCESS - This invention relates to an apparatus for vapor lubrication comprising a chamber, a diffuser plate having an array of orifices, a shutter plate having substantially the same pattern of orifices as that of the diffuser plate, a holder for holding an object to be vapor coated in the chamber, and an actuator to move the shutter plate to align the array of orifices of the shutter plate with the array of orifices of the diffuser plate or at least partially block the array of orifices of the diffuser plate with the diffuser plate. | 11-05-2009 |
20090318664 | LOW PROFILE LUBRICANT WITH CYCLOPHOSPHAZENE RING ATTACHED - A compound comprising a backbone with a perfluoropolyether chain. The compound also has one or more cyclophosphazene rings attached to or incorporated into the backbone. The compound further includes at least two functional groups attached to the backbone, attached to the one or more cyclophosphazene rings, or a combination thereof. | 12-24-2009 |
20100006595 | VACUUM SPRAY COATING OF LUBRICANT FOR MAGNETIC RECORDING MEDIA - Processing equipment for manufacturing magnetic recording medium comprising a chamber, a micro-dispensing valve that can open for a minimum time of less than a few microseconds and can dispense a liquid in an amount of a micro-liter or less each time that the micro-dispensing valve is opened, wherein the liquid comprising a lubricant and a solvent different from the lubricant is dispensed through the micro-dispensing valve. | 01-14-2010 |
20100035083 | MIXTURE OF LOW PROFILE LUBRICANT AND CYCLOPHOSPHAZENE COMPOUND - A composition comprising a mixture of a low profile lubricant and a compound comprising one or more cyclophosphazene rings. The low profile lubricant comprises a perfluoropolyether backbone, at least one functional group on each end of the backbone and at least one functional group located in a region of the backbone between the ends. Also a device comprising a magnetic disk and the composition on the magnetic disk. | 02-11-2010 |
20100092802 | MULTI-STEP ETCH PROCESS FOR GRANULAR MEDIA - A method of forming a granular magnetic recording medium comprises etching a cap layer disposed on a granular magnetic recording layer. The etching process is carried out at a varying ion energy, including a first ion energy and a lower subsequent second energy. A device including the etched cap layer is also disclosed. | 04-15-2010 |
20100129685 | RECORDING MEDIA WITH REDUCED MAGNETIC HEAD KEEPER SPACING, HEAD MEDIA SPACING, OR HEAD TO SOFT UNDERLAYER SPACING - Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing. | 05-27-2010 |
20110262633 | LUBRICANT DEPOSITION ONTO MAGNETIC MEDIA - A method, in one embodiment, can include pumping a gas into a reservoir that includes a lubricant. In addition, the method can include changing the gas into a supercritical fluid that extracts lubricant molecules from the lubricant resulting in a mixture of the supercritical fluid and the lubricant molecules. Furthermore, the method can include utilizing the mixture to deposit a lubricant molecule onto a magnetic media. | 10-27-2011 |
20120135274 | NON-HCP MAGNETIC LAYER - A magnetic film or layer includes a non-hexagonal close pack (non-hcp) structure. | 05-31-2012 |
20120141834 | REDUCED SPACING RECORDING APPARATUS - Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing. | 06-07-2012 |
20140212690 | REDUCED SPACING RECORDING APPARATUS - Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing.
