PURPOSE:To permit exact and easy evaluation measurement by disposing a conductive wire between a head gap part and coil conductor layer along the gap part near the gap part. CONSTITUTION:This thin film magnetic head has a lower magnetic layer 2 formed by means such as vapor deposition or sputtering on a magnetic or nonmagnetic material 1 consisting of, for example, ferrite or Al2O3-TiC or Al2O3. The head has the coil conductor layer 4 enclosed by the nonmagnetic insulating layer 3 consisting of SiO2, etc., thereon and is further laminated successively with an upper magnetic layer 6 and a protective layer 7 via a gap layer 5 thereon. This thin film head is provided with the conductor wire 9 between the head gap part 8 consisting of a prescribed gap length and the coil conductor layer 4 in the insulating layer 3 near the gap part. This conductor wire 9 is disposed along the gap part 8 and both ends thereof are formed as pads. The two magnetic layers 2, 6 form a closed magnetic path via the gap part 8 in the form of enclosing the coil conductor layer 4. |
