Dynamic Characteristics of Floating Head Mechanism : (2nd Report, Following Characteristics of Slider)

抄録

High capacity magnetic storage drums are obtained by means of small constant clearances between head cores and drum surface. An air floating head mechanism is a kind of head supporting methods and is of an application of self-acting air bearing. In this report, the following characteristics of the mechanism in vibration of the drum surface are described. By solving Reynolds equation and linearized equation of motion of the slider, the relative vibration of the trailing edge of the slider to that of drum surface, and conditions inducing the best following action and resonance with drum vibration were obtained. Numerical solutions of the nonlinear equation show that higher order vibrations appear as amplitude of the drum vibration increases. Theoretical results agree well with available experimental ones.
