Magnetic head that suppresses protrusion of medium facing surface caused by heat of coil |
摘要 |
A magnetic head includes a coil, a pole layer, and a coil adjacent layer. The coil includes a winding portion having two side surfaces. The coil adjacent layer is adjacent to at least part of the whole of the two side surfaces of the winding portion. The coil adjacent layer is formed of a nonmagnetic material having a linear thermal expansion coefficient of 5×10−6/° C. or smaller at a temperature of 25° C. to 100° C. and having a thermal conductivity of 40 W/m·K or higher at a temperature of 25° C.
