PURPOSE:To obtain a sliding contact member for a magnetic tape which is free from the deterioration in material quality and deformation, has excellent wear resistance and adhesiveness to a substrate and has a small coefft. of friction by implanting the ions of nitrogen or oxygen to the surface of the sliding contact member. CONSTITUTION:The member which makes sliding contact with the magnetic surface of the magnetic tape is constituted of one kind selected from a group consisting of Al, Al alloy, Ti and Ti alloy and the ions of the ionized nitrogen or oxygen are implanted at >=1X10<17> pieces ions/cm<2> are implanted onto the surface of the sliding contact member to form the nitride layer or oxide layer with the sliding contact member on at least the surface to make sliding contact with the magnetic tape. Since the accelerated ions are implanted, the nitride or oxide decreases the concn. from the surface to the inside of the sliding contact member and has no distinct boundary with the substrate. The good sliding contact member for the magnetic tape which has the good adhesiveness and decreases the deterioration in the material quality and the deformation to an extremely low level as the substrate is not heated is thus obtd.
