An, magnetoresistive thin-film magnetic head with high corrosion resistance for recording medium having massive capacity is provided by providing a protective film having a thickness of 40 Å or less. Since the distance between the head and the medium is remarkably reduced, the film is suitable for a recording medium having high-packing density. The magnetoresistive type thin-film magnetic head is provided, wherein a protective film made of a diamond-like thin film having the composition represented by the following formula: CHaObNcFdBePf (where a=0-0.7, b=0-1, c=0-1, d=0-1, e=0-1 and f=0-1, in terms of atomic ratio), and having a thickness of 40 Å or less, is formed on at least the surface of the head contacting a recording medium. Also provided are a method for producing the same, and a magnetic head device using the same.
