Magnetic head
 Disclosed herein is a magnetic head in which the sliding surface is constructed of a transducing gap, a pair of soft magnetic metal films opposite to each other through the transducing gap, and a substrate holding the soft magnetic metal film. The substrate is 20-200 times as wear-resistant as the soft magnetic metal film. The magnetic head has a gap depth of 1-5 .mu.m and produces an overall high head output.
