Abstract

A magnetic head of a magnetoresistance type is provided. The magnetic head comprises a magnetoresistance film, an underlying layer formed on each of both sides of the magnetoresistance film, and a magnetic-domain regulating film formed on the underlying layer so as to regulate a magnetic domain of a free magnetic layer in the magnetoresistance film. The underlying layer has a laminated structure of a tungsten-(W)-group metal layer formed on a tantalum-(Ta)-group metal layer. The underlying layer is formed so thick as to arrange the magnetic-domain regulating film at a position corresponding to the free magnetic layer.
