Abstract
In the low flying height magnetic disk drive, where the head is flying just 20–30 nm above the rotating disk surface, the possibility of mechanical damage to the head significantly increases. In fact, chipping and microcracks of the alumina of the thin-film head is a frequently encountered problem. The complex layered structure of the thin-film head contains many materials and interfaces. Interaction with the disk surface and thermal expansion of the head materials causes high mechanical stresses in the head alumina, which may result in a crack initiation and growth.
