PURPOSE:To avoid the output deterioration of a magnetic head due to attachment of an adhesive matter by forming grooves to the magnetic tape rubbing surface of the head and also protruded streaks which extend along the rubbing direction of a magnetic tape and have contacts with both end parts of a pad with a space secured to the magnetic tape to reduce the pressure contact force between the part and the tape. CONSTITUTION:The linear grooves 15 and 15 are formed in the prescribed width on a tape rubbing surface 6 and along the both edges of the coming-in side and the going-out side of a magnetic tape at a magnetic core part 2. The fixing agent 4 is removed out of the groove parts 15. Then, the protruded streaks 16 and 16 are formed on the surface 6 to sandwich an opening part 5a where the core is exposed on the surface 6 and then to enclose a magnetic tape rubbing area. Thus, both streaks 16 extend over the entire width of the surface 6 and along both edges of an approximately oblong surface 6 in the direction parallel to the tape rubbing direction. As a result, an adhesive matter is prevented from attaching to the part of the core 2 as the tape rubs. Then, the press contact force of a pad 11 is reduced and the wear of a magnetic core part is suppressed.
