Abstract

Magnetic recording density has increased remarkably due to progress in magnetic recording media. Metal-evaporated (ME) tapes may be the ultimate media for the coming era of digital magnetic recording. However, ME tapes are inferior to metal-particulate (MP) tapes in durability against the rubbing of magnetic heads. The use of organic and inorganic protective layers could improve two tradeoff properties such as high output and durability. In this paper, this recent technology is discussed from the viewpoint of tribology
