Abstract

A composite coating device includes first to third processing chambers. The first processing chamber performs an ion beam etching as a pretreatment process in which an ion beam is irradiated on a surface of a magnetic head at a predetermined angle and the surface is removed for a predetermined depth. The second processing chamber performs a magnetron sputter deposition as a shock absorbing coating formation process in which a shock absorbing coating is formed on the pretreated surface. The third processing chamber performs an electron cyclotron resonance plasma chemical vapor epitaxy or a cathode arc discharge deposition as an overcoat formation process in which an overcoat is formed on the shock absorbing coating. A preparation chamber communicates with the first to third processing chambers through opening and closing devices for transferring the magnetic head.
