Submicron spacing of self-loading flying head slider mechanism. 1st report. Fundamental research.

Abstract

This paper proposes a self-loading flying head slider mechanism, which operates under the non-contact start mode conditions with magnetic disk media in magnetic recording disk storage. Fundamental research was carried out. The flying head slider mechanism consists of a negative pressure air bearing slider, a slider suspension mechanism and a twin-structure piezoelectric actuator as the head-loading mechanism. The head-loading mechanism for the twin-structure piezoelectric actuator is confirmed to have good characteristics, simulating the mechanisms analysis. Furthe more, microdynamics and static characteristics for self-loading phenomenon of a negative pressure air bearing slider were computed and static and dynamic flying characteristics for self-loading flying head slider mechanism were analyzed, using the finite element method. As a result, it became clear that the self-loading negative pressure flying head slider mechanism proposed in this paper had good flying characteristics and high reliability. The feasibility for realizing a self-loading flying head slider mechanism, which operates under non-contact start stop mode conditions with magnetic disk media, was shown.
