Abstract:

A magnetic recording head and method for coating a magnetic recording head for use in a computer hard drive head arm assembly is provided. The head is treated with a silane, zirconate or titanate compound for coating magnetic surfaces to prevent atmospheric corrosion. The coating of the present invention protects the head during assembly, transport and storage, and advantageously wears off after repeated hard drive use, restoring the original fly height. The frictional contact between the head and the magnetic recording media keeps the head surfaces polished and corrosion free after the head is in use.
