摘要：
An apparatus and method for correcting static and dynamic imbalance with a single mass in a hard disk drive is disclosed. The method provides for determining a static imbalance of a hard disk assembly and for determining a dynamic imbalance of the hard disk assembly. A greater imbalance from the static imbalance and the dynamic imbalance is determined. A single mass is applied to the hard disk assembly to correct the greater imbalance.
