Abstract
A magnetic head is provided with a substrate and a magnetic field generating coil formed on the substrate. The substrate has a principal surface facing a storage disk and divided into an inner area and an outer area surrounding the inner region. The magnetic head also includes a dielectric layer enclosing the coil and facing the storage disk. The dielectric layer is formed in the inner area of the principal surface of the substrate but not in the outer area. As tilting, the storage disk comes into contact with the dielectric layer, thereby being prevented from bumping into the outer area of the principal surface of the substrate.
