9 ABSTRACT OF THE INVENTION This disclosure describes equipment and processes being capable of the high speed laser scribing of ferro- magnetic sheet material to produce a reduction in ferro- magnetic domain size in the material. The invention involves the elastic bending of sheet material around an axis which is parallel to the direction in which it is being translated and then laser scribing the curved sheet material. A rotating optical device is used to repeatedly send a focused laser beam across the width of the curved sheet material.
