Abstract

PURPOSE: To prevent cracks for a magnetic head core or glass by applying glass fusing while causing vacuum foam in the glass.
CONSTITUTION: After vacuum foam is generated in low melting point fused glasses 4, 5, the temperature in the furnace is decreased gradually till the room temperature. In this case, distortion takes place in the magnetic head core 1, the low melting point glasses 4, 5 and the sliders 2, 3 due to the difference from the thermal expansion coefficient among the magnetic head core 1, the low melting point glasses 4, 5 and the sliders 2, 3, but vacuum foaming is caused in the low melting point glasses 4, 5, then the distortion as above is absorbed in the vacuum foam. Thus, cracks for the magnetic head core 1 and the low melting point glasses 4, 5 are prevented in this process.
