In one embodiment, the invention is directed toward a magneto-optic read head formed to suppress magnetic exchange coupling at regular intervals along a lateral direction of the read head. For example, in the region of the magneto-optic read head where light is reflected, i.e., the optical scanning region, the read head may be formed with a series of ferromagnetic exchange breaks that reduce lateral permeability of magnetic fields, and hence reduce lateral flux through the read head. In this manner, the effective resolution of the read head can be increased, thereby facilitating readout of data stored on narrower data tracks.
