PURPOSE:To improve an electromagnetic characteristic and prolong a service life by providing an electromagnetic converting gap position in a specific position and holding the change of a spacing in an electromagnetic converting gap part small even when a form change occur around the gap. CONSTITUTION:A magnetic head is formed with nearly cylindrical read block 2 and write block 3. Electromagnetic gaps 4 and 5 having plural built-in thin film elements for electromagnetic converting in the central parts of the blocks 4 and 5. Plural grooves 8 are provided in parallel on both the sides of the gap 4 and in front of the gap 5. A magnetic tape runs through on the medium facing surface of the magnetic head 1 and the recording and the reproducing of data are executed. At this time, the gap part spacing increases and cylindrical part spacing decreases, therefore, when the electromagnetic converting gap position is made in the cylindrical spacing, the change of the electromagnetic converting gap part can be held small even when the form change occur around the gap and the electromagnetic characteristic and the service life can be improved. |
