Zusammenfassung:	PURPOSE:To suppress wiggle and to prevent the demagnetization of recording and the cracking of a protective film by setting the distance from the boundary point between the yoke region of an upper magnetic film and the rising part of a pole region to an air bearing surface in a specific range. CONSTITUTION:The distance D from a displacement point Y which is the boundary between the yoke region 42 of the upper magnetic film 4 and the rising part of the pole region 41 up to the air bearing surface 103 is set in the 2mum
