A magnetic structure and a magnetic head capable of reducing the size thereof and raising the degree of integration is disclosed which has a structure including a substrate having a plurality of ridge-like projections each having slant side-surfaces; the substrate having thereon: a first conductive passage consisting of a plurality of parallel and conductive passages each of which is formed on opposing slant surfaces of adjacent projections and on the bottom surface between the slant surfaces; a first insulating layer stacked on the first conductive passage and the substrate; a magnetic core made of magnetic material enclosed in a groove-shape recess formed by the adjacent projections and the bottom surface; a second insulating layer stacked on the magnetic core; and a second conductive passage formed on the second insulating layer to sequentially connect ends of the first conductive passage to form a helical coil, wherein the magnetic core is separated by the projection so that a plurality of coils are integrally formed on the same substrate.
An apparatus including a magnetic head having a plurality of magnetic head chips formed on a common substrate thereof, said apparatus comprising:
