<p>A thin-film magnetic head which has a structure wherein a spiral conductor coil (13) having a plurality of turns (13a, 13b, 13c, 13d) is disposed between first and second magnetic layers (11,16) being substantially in parallel with each other, through upper and lower inorganic insulator layers (12, 14), and in which a part of the outermost turn (13a) of the conductor coil (13) is exposed on a face opposite a magnetic recording medium along with the upper and lower inorganic insulator layers (12. 14) to form a magnetic gap. This head can be readily manufactured by a manufacturing method including the step of forming the outermost turn of the conductor coil on the side of the face opposite the magnetic recording medium so as to be wider than any other part of the conductor coil, and the step of thereafter machining the face opposite the magnetic recording medium so as to expose the outermost turn of the conductor coil on the face opposite the magnetic recording medium. The magnetic head of the present invention is suited to high-density recording. and is high in recording and reproducing efficiencies and also in reliability.</p> |
