Abstract

PURPOSE:To obtain a core chip having excellent sliding characteristics in which a glass film containing bubbles, etc., is not exposed from a slidable contact surface of a magnetic head with a medium. CONSTITUTION:A magnetic head is formed by opposing a pair of cores made by interposing a metal layer made of a magnetic material between nonmagnetic boards and glass fusion-bonding them to the metal layer to be integrally connected, and forming a magnetic gap at a slidable contact surface of a medium. The metal layer is covered on upper and lower ends with SiO or Al2O3 nonmagnetic films, and the films are exposed from the slidable contact surfaces of the medium. A method for manufacturing the head comprises the steps of covering one ends of a plurality of square rodlike nonmagnetic boards 12 with metal layers 2, and laminating its upper and lower ends with nonmagnetic films 6A, 6B. Then, the method further comprises the steps of covering a part between upper and lower nonmagnetic films on the metal layer with fusion- bonding glass film 11, aligning a plurality of nonmagnetic boards 12, butting side ends of adjacent metal layer side and nonmetal layer side, glass fusion- bonding them, then perpendicularly crossing it with a connecting surface, and slicing it to form core blocks.
