VIBRATION ISOLATION MEASURE

摘要

PURPOSE: A vibration isolation measure is provided to reduce vibration to be transferred to a hard disc by forming vibration isolation measure including a sleeve tube suitable to install in a hole. CONSTITUTION: A housing is there. A spindle motor(14) is adhered to the housing. A motor closing measure(34) is adhered to the spindle motor(14). A motor vibration isolation measure(38) is located between the motor closing measure(34) and housing. A disc(12) is rotated by the spindle motor(14). A bearing assembly(23) is adhered to the housing. An actuator arm(22) is adhered to the bearing assembly(23). A head is connected magnetically to the actuator arm(22) and to the disc(12). A voice coil motor can rotate the actuator arm(22) in relation with the disc(12), and move the head. A hard disc drive includes more the bearing closing measure which is adhered to the bearing assembly(23) and the housing, and the bearing vibration isolation measure(40) located between the bearing closing measure and the housing.
