Abstract: Non-magnetic ferrite composition used in the composite multilayer part of the invention is based on ferrite containing Fe.sub.2 O.sub.3 and CuO and/or ZnO and further contains 1 to 30% by weight of four oxide components of MgO, BaO, SiO.sub.2, and B.sub.2 O.sub.3 or five or six oxide components including the four oxide components plus at least one of SnO.sub.2 and CaO. Since the use of this non-magnetic ferrite minimizes the difference in coefficient of linear expansion between different materials used, the non-magnetic ferrite, when applied to composite multilayer parts such as shielded multilayer chip inductors, shielded multilayer transformers, and multilayer LC composite parts, prevents occurrence of cracks in the interior and avoids a lowering of circuit resistance due to precipitation of CuO, ZnO or the like at the interface between different materials. There result composite multilayer parts with improved characteristics.

Abstract: To improve the sliding characteristics of a magnetic head by reducing a friction coefficient, and realize a magnetic recording medium with a high recording density and a large capacity, capable of reducing the flotation distance of the magnetic head. On the surface of a base, aluminum containing nitrogen aggregates locally to form islands of metal deposits, which are distributed discretely over the entire surface of the base. Meanwhile, on the metal deposits, a metal base layer, a magnetic layer, a protective layer, and a lubrication layer are laminated sequentially to form a magnetic recording disk. On the disk surface, ultrafine irregularities are formed that reflect the shapes of the metal deposits, thereby realizing a reduction in the friction coefficient.
