A review of the corrosion of thin films used for magnetic recording is presented, with a focus on mechanisms of indoor atmospheric corrosion and corrosion protection. Predominant factors that lead to corrosion are moisture and gaseous pollutants. Corrosion products, for alloys of interest, are localized as opposed to uniform tarnish films. Corrosion resistance can be achieved by modifying magnetic film composition, by overcoats, and by undercoats. The effect of these on magnetic recording properties is addressed. With proper design, attenuation of the environment from equipment enclosures can protect against corrosion.
