<p>PURPOSE:To obtain extremely high reliability by obviating the unstable traveling property between a magnetic tape and a traveling regulating post and the generation of damages, such as flawing and peeling, of the magnetic layer of the magnetic tape. CONSTITUTION:This traveling regulating post for the magnetic tape is constituted by using a base body 1 consisting of an aluminum/silicon alloy as the traveling regulating post material for the magnetic tape, selectively eluting an aluminum base surface 2 in the surface layer part thereof to project silicon particles 3 from the aluminum base surface 2 and further disposing a protective film 4 consisting of diamond or diamond-like carbon thereon. The high reliability of the magnetic tape is maintained over a long period of time by such post.</p> |
