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 extention 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 the effect of increasing these resonance speeds; whereas the external damping makes the disk deflection asymmetric with respect to the applied force. The restraining effect of a liner used in an available floppy disk cartridge on the disk deflection is clarified by the numerical analysis for a disk model supported partly by a set of external springs. Theoretical results are roughly verified by the experiments.
