摘要： A method of producing a thin film magnetic head comprises forming a thin film magnetic circuit including a magnetic film and a conductive coil film on a substrate, and heating the thin film magnetic circuit at a temperature in a range of from 270.degree. C. to 400.degree. C. before forming a protective layer covering the thin film magnetic circuit.

摘要： A tape lead wire includes a polymer resin film and conductor films. The conductor films are directly deposited on the surface of the polymer resin film without using any bonding layer. The total thickness of the tape lead wire can be made smaller than that of a conventional lead wire. The tape lead wire has a high flexibility, can be easily bent, can extremely reduce the bending spring rigidity and is suitable for a magnetic head having a reduced size and load, which is imposed by a head supporting device on the magnetic head, and lowered flying height and peripheral speed.
