Abstract

PURPOSE:To perform satisfactory glass molding by using two kinds of mold glass, which are different in softening point and have compositions approximating each other as much as possible, to arrange a groove for winding window. CONSTITUTION:Track grooves 3, a glass groove 4, and a groove 5 for winding window are formed in each of block materials A and B. After metallic films having a high saturation magnetic flux density are formed, track grooves are butted on an SiO2 spacer between them. A low-melting point mold glass 6 is arranged in parts corresponding to grooves 4, and a margin is provided in the rear gap direction of the groove 5. A high-melting point glass 7 which has the same composition as the glass 6 and has a diameter smaller than that of the glass 6 is arranged in a window 5. They are fused by heating and are unified. The high-melting point glass 7 is used as the guide of the low-melting point glass to fill up grooves with glass, and the window is not filled.
