Abstract

PURPOSE:To improve durability by increasing wear resistance by decreasing a coefficient of friction, by providing a silicon compound, containing specific F, on a magnetic-layer side surface. CONSTITUTION:A 0.1-10wt% compound shown by the formula is contained in magnetic powder to form a magnetic layer. The said compound bleeds the magnetic layer to the surface to decrease a coefficient of friction extremely. Thus, a magnetic tape, etc., which has wear resistance and superior durability is obtained.
