Abstract

In order to get a better understanding of head to flexible disk interface problems, Green's function for a spinning flexible disk deflection is derived by extension of the analytical method proposed for a stationary flexible disk in the previous paper. As a result, it is found that a flexible disk has many resonance speeds where each circumferential mode component is excited by a stationary force. The external stiffness has an effect to increase these resonance speeds, whereas the external damping makes the disk deflection asymmetric with respect to the applied force. Restraining effect of a liner used in an available floppy disk cartridge on the disk deflection is clarified by the numerical analysis of a disk model supported partially by a set of external springs. Theoretical results are roughly verified by experiments.
