Abstract
A balancing apparatus for balancing a high precision magnetic disk drive includes a plate having a circular aperture in which three mounting surfaces grip a precision mounting ring on the disk pack to be balanced. The plate is mounted on a pivoting platform so that the pack can be lowered into the aperture, gripped by the mounting surfaces and then flipped into a horizontal position for balancing such that an operator has access to the disk pack to add balancing weights through the circular aperture.
