The decreasing of flying hight between the slider and the disk is one of the most important items in promoting the further increase of the recording density. In order to develop a new material for the slider that is able to meet such a requirement, we have examined the CSS test and the DRAG test for various kinds of slider materials. An evaluation of slider materials based on the results of these two tests was made and the results were compared with the properties of each ceramic slider materials. These test results would show a good correlation with the micro-tribological phenomena between the slider and the disk. As a supplemental test, the contact angles of ultra-pure water dropped on the polished slider substrate were measured.
