Abstract
An adjustable disk stabilizer for a spinstand having a spindle motor and spindle assembly for supporting and rotating a magnetic medium bearing disk. The spinstand is adapted to position a transducing (read/write) head adjacent to the magnetic medium. The adjustable disk stabilizer is attached to a stationary portion of the spindle assembly, and includes a mechanism to adjust height and alignment of a plate having a bearing surface opposite a non-magnetic-media-bearing undersurface of the disk. That bearing surface, in concert with the undersurface of the disk, establishes a supporting air bearing therebetween during rotation of the media-bearing disk. The adjustment mechanism enables easily-attained compensation for various disk-to-disk thicknesses and level imperfections of the bearing surface plate mounting, and enables precision alignment of the bearing surface of the plate to the surface of the disk opposite to the surface under test.
