Corrosion and Its Prevention of Thin Film Magnetic Head

摘要

Thin film magnetic heads for high recording density rigid disk drives are composed of ceramics and metal multilayers. These metals take important role for read and write of information storage. It is a vital wound if the thin film metals suffer corrosion attack. Therefore, corrosion of thin film magnetic heads has been studied with surface analysis and electrochemical techniques in several related organizations. The author hopes some data introduced in this paper would helpful for comprehension of corrosion of magnetic heads and for prevention of the corrosion.
