Abstract
A small magnetic head is directly formed on a semiconductor substrate by using diffusion or evaporation techniques. A number of such small magnetic heads may be formed on the same substrate with high precision and high uniformity, and this is useful for constructing a multi-track head. If desired, a semiconductor integrated circuit may also be formed directly on the aforesaid semiconductor substrate.
