ABSTRACT
This chapter doiscusses the construction of tape, but also the materials used in the general-purpose particulate tapes and the recent development of both monolithic thin-film tapes and double-coated particulate metal tapes. In a thin-film head fabrication process, permalloy and copper can be deposited by evaporation, sputtering, or plating. In order to eliminate these undershoot signals, a pole edge-eliminated head is proposed to remove the undershoot signal. The head-disk interface in hard disk files is explained widely and in detail by Bhushan. Magnetic tapes are divided into two groups: particulate tapes where magnetic particles are dispersed in a polymer binder with some additives, and coated onto the substrate, and thin film media of which monolithic magnetic thin films are deposited onto the substrate in vacuum. However, abrasives remove the mating head materials; then the amount of abrasives is considered to maintain low head wear.
