In a magnetic head including a multi-layer coil for generating a magnetic field, and a flat, magnetic field regulator (5A, 5B) spaced from the coil along the central axis of the coil, the field regulator (5A, 5B) is formed with a center hole (50) for passing disk-illuminating light and the magnetic member (5A, 5B) consists of a plurality of sections (52a, 52b) that are electrically insulated and arranged around the central axis of the coil. <IMAGE> <IMAGE>
