A magnetic head for write and read of information, the core of which is at least in part composed of magnetic metal thin layers and non-magnetic intermediate metal oxide layers alternately laminated is provided. The metal is a cobalt base amorphous alloy or permalloy and the metal oxide is selected from SiO, Al2O3, MgO and BaTiO3, which has a Vickers hardness of not less than 200 to less than 1,200. The use of the magnetic head does not injure a magnetic recording medium and contributes to improvement of the durability of the magnetic recording medium.
