Abstract
The idea of a curved stabilizer with damping
orifices is applied to the high speed rotating flexible optical disk system in order to reduce the disk deflection and the axial run-out of the disk. A track of orifices is drilled along the edge of a curved annular stabilizer. The effects of the
diameter and length of each orifice, number of orifices, and radial position of the orifices on the reduction of axial runout of the disk are investigated experimentally together with the effects of the inner radius for the air flow, initial gap height, and rotational speed. The experimental results
showed that the curved stabilizer with orifices can reduce the axial run-out of the disk at 10,000 rpm within 0.010 mm over the entire span of the disk.
