The Stability

This paper presents a study on the stability of a 2″ floppy disk drive system. A design method of the disk stabilizer that makes the rotating disk stable is presented. The stabilizer and the read/write head are both modeled by springs with high axial stiffnesses. The stiffness of the air film surrounding the disk is determined from the Navier-Stokes equation as a function of the flow rate of the air within the disk jacket. The solution is obtained by using the multi-modal expansion approximation and applying the Galerkin method to the resulting equations. Numerical results show that the 2″ floppy disk rotating at 3600 rpm is unstable without the stabilizer. Further, it is shown that the stability of the disk is much affected by the geometrical configuration of the stabilizer attached to the rotating disk. A stabilizer that contacts the disk at four points was found quite effective in stabilizing the 2″ disk working at 3600 rpm.

Power Microwave

The electromagnetic coupling characteristics of a computer box under the high-power microwave (HPM) which includes the narrow-band and ultra-wideband HPM are studied. The simulations of radiation field in the computer box show that the optical drive and floppy disk drive are main channels through which the high-power microwave penetrates. The cut-off frequency of this corresponding dielectric waveguide and resonant frequency of computer box are the frequencies on which the coupling field is enhanced. The induced current on the cable show that the peak current value decreases with the increasing frequency. At the same time, the damage effect experiments of the computer under high-power microwave are carried out and the thresholds of three effect levels are summarized. The experimental results and the simulation are verified to some extent.
