摘要：
Apparatus and method for balancing and limiting deflection of a disc of a disc drive. A disc stack comprises a spindle motor hub rotatable about a central axis, a disc mounted to the spindle motor hub, and a circumferentially extending peripheral disc ring affixed to an outermost peripheral surface of the disc. Imbalance of the disc stack is measured, and portions of the peripheral disc ring are removed in relation to the measured imbalance of the disc stack to nominally balance the disc stack. The disc ring protects the disc drive by cushioning contact between the disc and a rigid actuator arm supporting a head adjacent the disc.
