Abstract
A new structure disk was developed for a magneto-optical (MO) composit e head system. The new disk has a thin readout substrate under and a h igh magnetic permeability layer over the MO layer. The effect of the h igh magnetic permeability layer was confirmed experimentally and agree d well with theoretical results. The normal component of the magnetic field at the MO layer is enhanced 1.6 times by the high magnetic perme ability layer.
