ABSTRACT:
A magnetic head applies a magnetic field to a desired area when recording an information signal on the desired recording area of a magneto-optical disk. This magnetic head comprises a printed circuit board and a coil formed on at least one of the surfaces of the printed circuit board by a conductor pattern. This magnetic head can be made smaller, lighter and thinner than conventional magnetic heads.
