Abstract

A composite type thin-film magnetic head is provided, which comprises: a write head element; a pair of terminal pads for the write head element; a pair of lead conductors for the write head element, electrically connecting the write head element to the pair of terminal pads for the write head element; a read head element; a pair of terminal pads for the read head element; and a pair of lead conductors for the read head element, electrically connecting the read head element to the pair of terminal pads for the read head element. The pair of lead conductors for the write head element and the pair of lead conductors for the read head element are formed into patterns that have no overlapped portions with each other through only an insulating layer.
