Effect of acrylic acid vapour on lubricated recording hard-disk media surfaces

Magnetic recording hard-disk drive may be attacked by many kinds of contaminations including vapours/gases. Vapour/gas contaminants are detrimental to magnetic heads, media and head–disk interfaces in hard-disk drive. Acrylic acid is a kind of gases released from drive components. In this study, the effects of acrylic acid vapour on the surface adsorption and corrosion of magnetic hard-disk media are investigated by TOF-SIMS. The related drive durability and failure property are discussed.
