floating magnetic head

Abstract

Abstract PURPOSE:To reduce damage while using a magnetic head and to improve durability by providing a rugged part having a prescribed step height and a rugged part area rate on the floating face of the floating magnetic head. CONSTITUTION:On floating faces 2 and 4 of the floating magnetic head, the rugged parts are formed with steps and prescribed shapes. In that case, the height of the step is set to 30-500Angstrom and the area rate of the apex part of a projecting part is set to 10-75% of the floating face. Thus, the area of true contact between the magnetic head and the magnetic disk is reduced, and an adhesive phenomenon is prevented. Further, since friction force between the magnetic head and the magnetic disk is reduced in the case of CSS, the damage for the magnetic head is reduced, and the durability of the magnetic head is improved.
