Abstract
A magnetic head includes a coil, and a magnetic path forming section for defining a first space for a portion of the coil to pass through. The magnetic path forming section includes a core section. The coil includes a first winding portion and a second winding portion connected in series. The first winding portion includes one or two first coil elements extending to pass through the first space, and extends once or twice around the entire perimeter of the core section. The second winding portion does not pass through the first space, and extends less than once around the entire perimeter of the core section to rotate n degrees about a center point of the core section, where n is greater than 270 and smaller than 360.
