摘要：
An optical disc storage system (10) includes an optical disc (12) having a data surface (70) and a transducing element (30) adjacent the data surface (70). An actuator (22) coupled to the transducing element (30) positions the transducing element (30) relative to the data surface (70). The system (10) includes a spindle motor (90) and a controller (34) coupled to the transducing element (30), the actuator (22) and the spindle motor (90) for reading and writing information on the data surface (70). A hub insert (72) is coupled to the optical disc (12) and has a stiffness which is greater than a stiffness of the optical disc (12). An attachment mechanism (94, 96, 98) couples the hub insert (72) to the spindle motor (90) and stress due to the attachment mechanism (94, 96, 98) remains substantially in the hub insert (72) to thereby limit stress applied to the optical disc (12) and the resultant distortion of the optical disc (12).
