IPC: C23F1/00
Filed: 1992-10-04
Abstract: PURPOSE:To completely remove only the three layer of sputtered films without damaging the wet plated surface of the lower layer by immersing an aluminum substrate hard disk formed with a carbon protective film as its uppermost layer into a concd. hydrochlroric aid or an acid mixture containing hydrochloric acid. CONSTITUTION:The defective article of the hard disk formed by laminating three layers of the thin films by sputtering in order of carbon, cobalt and chromium successively from the upper layers on the disk surface and subjecting the lower layer thereof to electroless wet plating of nickel and phosphorus is immersed into the concd. hydrochloric acid or the acid mixture composed essentially of hydrochloric acid. The carbon protective film of the extreme surface is extremely thin and has always defects, such as slight pinholes, and therefore, the hydrochloric acid infiltrating thereform dissolves the metallic film of the lower layer without dissolving the wet plating surface. The entire part of the carbon film is, therefore, dislodged and peeled in the undissolved state from the disk surface in the final. The hard disk after the peeling is completely dried after washing with pure water or is transferred while the disk is held immersed in an alkaline soln., by which the resputterable surface is obtd.
