Abstract: The present application provides an edible pet chew having a moisture content of 15 to 30 wt % and contains 15 to 35 wt % of gelatin, 10 to 30 wt % of flavoring ingredients, 2 to 10 wt % of structure-providing components, 1 to 5 wt % of humectant, 0.1 to 0.2 wt % of preservatives, and 10 to 25 wt % of a dental protection composition. The present application also provides a chewable rope embodiment containing a rope either impregnated with 10 to 25 wt % of a dental protection composition or containing a rope coated with the edible pet chew formulation.

Abstract: A stamper having a patterned layer composed of a hard material and a compressible material back plane layer. The back plane layer may be composed of an elastomer. The stamper may be used to imprint an embossable layer disposed above a substrate for the production of a magnetic recording disk.

Abstract: The present invention relates to active delivery system formulations, and methods of making and using the same. Said formulations, when applied to a substrate surface, form a protective coating on the surface and permit constituent active agents to act on the surface and in the surrounding medium.

Abstract: A method and apparatus is described for gradually transitioning a slider from operation over a patterned data zone to landing on a patterned CSS zone. The ratio of raised area width to recessed area width of a pattern in a transition zone and/or CSS zone may be varied across the radial dimension of the disk. By changing the ratio of raised area width to recessed area width of the pattern in the transition from slider operation over the data zone to landing in the CSS zone, it is possible to gradually change the height of the slider from flying to non-flying conditions.

Abstract: A method for polishing a glass or glass ceramic substrate comprises the step of using a slurry comprising both diamond and CeO2 particles. We have discovered that the presence of both diamond and CeO2 particles permits one to polish at a high glass removal rate, and concurrently, to leave a texture on the surface of the glass substrate.

Abstract: A slurry in accordance with the invention comprises CeO2 polishing particles and sodium polyacrylate in an aqueous solution. This slurry is used to polish a glass or glass ceramic substrate. I have discovered that adding sodium polyacrylate to a CeO2 slurry improves the polishing rate without causing a major negative impact on the slurry stability or redispersibility. In addition, the addition of the sodium polyacrylate does not cause a great deal of foaming. This polishing process can be used to prepare substrates for the manufacture of magnetic disks.

Abstract: A contact start/stop (CSS) disk file has an improved head-disk interface which has significantly reduced static friction between the head-supporting slider and the disk. The slider has a plurality of narrow skids which project from the air-bearing surface of the slider and support the air-bearing surface off the disk when the disk file is not operating. The skids are designed to not affect the flyability of the slider and contain a protective overcoat to minimize wear at the head-disk interface.

Abstract: A data recording disk file of the liquid-bearing type has an improved head-disk interface provided by a transducer carrier with new properties. The carrier supports a conventional head for reading and writing data to the disk. The carrier has an air-bearing surface near its front end, a ski pad near its rear end, and a plurality of ski feet or struts which support the air-bearing surface off the liquid film of the disk when the disk file is not operating. The air-bearing surface is in the form of a pair of air-bearing rails located forward and outboard of the rear ski pad so that no air-bearing effect occurs in the rearward region of the carrier to assure the skiing action of the rear ski pad. The struts are separated from the air-bearing rails to not interfere with their air-bearing performance and support the rails away from the liquid film on the disk.

The air-bearing surface is in the form of a pair of air-bearing rails located outboard of the rear ski pad so that no air-bearing effect occurs in the rearward region of the carrier to assure the skiing action of the rear ski pad. As operational speed is approached the air-bearing lifts the struts off the disk and the rear ski pad is the sole ski foot on the liquid film.

Abstract: A disk file with substantially reduced head-disk spacing and corresponding improvement in recording performance uses a disk coated with a film of conventional high viscosity lubricant, a lubricant reservoir for replenishing the lubricant on the disk over the life of the file, and a transducer carrier with feet which ski on the high viscosity liquid film. The file does not include any means for recirculating the lubricant since the lubricant spins off the disk at a relatively low rate due to its high viscosity. The lubricant reservoir contains a very small amount of lubricant and thus may be maintained inside the substantially sealed disk file. In one embodiment of the invention, the sealed disk file is essentially evacuated. The operation of the disk file in a near vacuum environment is possible because, unlike conventional disk files, air is not required to support an air-bearing head-disk interface and the high vapor pressure of the relatively high molecular weight lubricant prevents its evaporation.
