摘要：
Glass-ceramic substrates based on the lithium silicate system have been found to have excellent tribological performance, associated with the inherent bump topography produced by differential polishing of alpha-quartz and a lithium silicate/glass matrix. This paper explores the extendibility of lithium silicate alternative substrates to meet the needs of recording media for use at densities approaching and exceeding 1 Gb/in(2). Flatness, topography, magnetic performance, and resistance to environmental attack are shown to be extendible to higher density, and alternatives to the inherent bump topography are presented.
