Abstract
A manufacturing method for a thin-film magnetic head including first and second magnetic layers, a gap layer, a thin-film coil, and a coil insulating layer for insulating neighboring ones of turns of the thin-film coil. The manufacturing method includes the steps of: forming the first magnetic layer; forming the gap layer on the first magnetic layer; forming the second magnetic layer on the gap layer; forming the thin-film coil; and forming the coil insulating layer. The coil insulating layer is formed by stacking a plurality of insulating films formed by chemical vapor deposition.
