Abstract:
The method of fabricating a magnetic head slider includes steps of: forming a first protective film on an air bearing surface of a magnetic head slider on which either a recording element or a reproduction element is formed or on which both a recording element and a reproduction element are formed; removing a portion of the first protective film to reduce the thickness of the first protective film and forming a second protective film over the first protective film that has been reduced in thickness; and forming an uneven portion for controlling the flying characteristics of the magnetic head slider on the air bearing surface of the magnetic head slider; wherein the formation of the uneven portion is carried out after the first protective film has been formed and before the second protective film is formed, or after the second protective film has been formed.
