ABSTRACT:
A magnetic head for magnetooptical recording includes a substrate, a magnetic core provided on the substrate, a coil wound on the magnetic core, and a drive device for driving the coil. Further, a reinforcing member is provided around the coil so that the substrate is reinforced. The reinforcing member contains thermosetting resinous material. The thermal expansion coefficient of the reinforcing member is selected to be substantially equal to that of the substrate.
