Abstract
It is an object of the invention to improve characteristics of a thin-film magnetic head in the case where the frequency of data to write is high, in particular. In a thin-film magnetic head of the invention an induction-type magnetic transducer includes two magnetic pole layers and a thin-film coil placed between the pole layers and insulated from the pole layers. The distance between the outermost end of the coil and a medium facing surface is greater than a throat height and measures 10 &mgr;m or less.
