摘要： PROBLEM TO BE SOLVED: To provide a thin-film magnetic head that can obtain a large reproduced output by miniaturizing it to meet the demand for high density recording and suppress overheating, and to provide its manufacturing method and a disk drive using this head. SOLUTION: A heat radiation layer is provided neighboring the magnetic transducer layer on the reverse of its side facing the recording medium, to radiate the heat generated by the transducer layer. On the side opposite to the side facing the recording medium, the edge is formed to 2nm thickness or larger but 30nm thickness or smaller. By this, the heat of the magnetic transducer layer is radiated more effectively than before, to control the temperature rise. Thus, it becomes possible to suppress the electrical resistance increase and obtain a larger reproduced output. COPYRIGHT: (C)2004,JPO

The lower magnetic pole layer 7 and the upper magnetic pole layer 14 are formed of NiFe, high saturation magnetic flux density material, etc. The lower magnetic pole layer 7 and the upper magnetic pole layer 14 come into contact with each other and are magnetically connected via contact holes 8a. The throat height Th-H is a length from a medium-facing surface 20 to the end on the medium- facing surface 20 side of the photoresist 9. The distance d between the outermost peripheral ends of the thin-film coils 10, 12 and the recording medium surface 20 is set larger than the throat height Th-H and below 10 μm with respect to the direction parallel with the surface of the recording gap layer 8.
