Abstract:
Embodiments of the invention provide a magnetic film capable of providing a higher saturation magnetic flux density as compared with the conventional one, a process of forming the magnetic film, a thin film magnetic head that makes use of the magnetic film, and a magnetic disk drive having this thin film magnetic head. In one embodiment, a magnetic film contains Co, Ni, and Fe, and its composition is such that 10≦Co
