Zusammenfassung:An inductive/MR composite type thin-film magnetic head. In one embodiment, the inductive/MR composite type thin-film magnetic head is equipped with an inductive head used for writing. The inductive head includes an insulating film and a conductive coil that are laminated between upper and lower magnetic films. The inductive/MR composite type thin-film magnetic head also includes a magnetic resistance (MR) head used for read-out. The inductive/MR composite type thin-film magnetic head is characterized by the fact that a distance L between [i] the upper and lower magnetic poles, which face each other across a magnetic gap at the tip ends of the aforementioned upper and lower magnetic films and [ii] the point where the aforementioned upper and lower magnetic films are joined together has the relationship of L
