Magnetic head with sectioned magnetic field regulator

   
   

A magnetic head includes a multi-layer coil for generating a magnetic field, and a flat, magnetic field regulator spaced from the coil along the central axis of the coil. The field regulator is formed with a center hole for passing disk-illuminating light. The magnetic member consists of a plurality of sections that are electrically insulated and arranged around the central axis of the coil.
