Hard Disk Drive (HDD) is one of the most widely used storage accessory, which uses magnetic recording to store data.

A micro-rotating machinery such as hard disk drive (HDD) requires high efficiency and robust dynamics in high operating speed.

This paper briefly introduces the structure of hard disk driver and analyses the defect of hard disk driver medium that possibly prduces in the manufacturing process,as well as influence in the process of use and also analyses other possible reasons that bring about hard disk driver medium damag

To demonstrate the feasibility and effectiveness of multi-mode vibration suppressing of this piezoelectric shunt damping system,the multiple mode vibration control experiments on the actuator of a hard disk driver was performed.
