Micro-systems mechanics VOLUME III

Including :3 parts. With decreasing flying height of the slider arm in hard disk drives, the thin film on the disk surface becomes more and more critical for a stable working condition. In this project, the spreading behaviour of thin liquid PFPE on hard disk surface was investigated theoretically....
