| description | Recent work has demonstrated that a relationship exists between the energy expended and the tip radius of the conic section on carbo-tribological writing equipment. Current energy conservation policy dictates that the tip radius should be maintained as small as possible, and computer studies indicate that a radius of 45 Å is the most effective. Current equipment for producing tip radii are inadequate, typical values being in the order of 5 μm. This paper describes work done on equipment to improve tip radius. A prototype model has been built and results indicate the possibility of maintaining the desired optimum. Suggestions for further development work are discussed. |
