Thin film magnetic head, a magnetic head device, a magnetic disk drive device, and a method for manufacturing a thin film magnetic device

A thin film magnetic head, which is driven at a given skew angle in a radial direction of a magnetic disk, comprising a slider and an inductive type electromagnetic conversion element, supported by the slider, including a first magnetic film, a second magnetic film and a coil film,

• one edge portion of the first magnetic film is positioned at an air bearing surface side of the thin film magnetic head, the first magnetic film being extended backward from the air bearing surface,
• one edge portion of the second magnetic film being opposed to the one edge portion of the first magnetic film by a given distance in the air bearing surface side and having, in a track width direction of the thin film magnetic head, at least one inclined side surface having an inclination angle not less than the maximum skew angle, the second magnetic film being positioned at a trailing edge side of the thin film magnetic head relative to the first magnetic film and extended backward from the air bearing surface, joined with the first magnetic film,
• the coil film being whirled around the magnetic circuit composed of the first and the second magnetic films.
