ABSTRACT:
A floating magnetic head device in which a slider carrying a magnetic head is supported by a supporting member. An intermediate layer composed of elements of the groups III or IV of the Periodic Table and an upper layer composed of hard carbon are sequentially deposited at least on the surface of slide rails formed on the major surface of the slider operating as a floating surface. It is possible with the floating magnetic head device to reduce the abrasion and sticking between the slider and the magnetic disc for improving abrasion resistance and CSS durability of the slider and the magnetic disc as well as durability and operational reliability of the magnetic head and the magnetic disc as articles of commerce.
