1. A magneto-optical head comprising:

  • a slider held in facing relation to a storage medium;

    an objective lens supported by the slider for concentrating light rays;

    a coil provided with a center through which the light rays pass, the coil including a first conductive pattern and a second conductive pattern which is closer to the storage medium than the first conductive pattern is; and

    a transparent insulating layer enclosing the coil;

    wherein the second conductive pattern is smaller in inner diameter than the first conductive pattern, the insulating layer filling the center of the coil.
