  • Abstract
    To analyze lubricant loss by head sliding, change in lubricant thickness during sliding under a flat-circular-surface pin (FC pin) on a thin-film magnetic disk is compared with that of a spherical-surface pin (S pin). Lubricant pick-up onto the PC pin was much smaller than that onto the S pin. And the amount of lubricant loss under the FC pin was smaller than that under the S pin. We consider the cause of this is the difference in the angle of the side wall at the trailing edge of the pins
