Abstract
PURPOSE: To obtain a magnetic head which has a gap of regular length and generates little chipping, by sticking a thin film of high melting point glass to the gap surface of ferrite chip by evaporation, sputtering, etc., and subsequently joining a pair of chips mentioned above by use of low melting point glass.
CONSTITUTION: Thin films 4 whose thickness is half of the setting gap length are formed by sticking high melting point glass (softening point: about 500W800°C) to the gap forming surface of ferrite chip 1 by means of vapor deposition or sputtering which causes little diffusion phenomenon. Subsequently, chips 1 and 1, and thin films 4 and 4 are touched and stuck, the low melting point glass 5 whose working temperature is over the slow cooling point of the aforesaid high melting point glass and below the softening point is poured into the part of glass thin films 4 in the melted state, and the chips 1 and 1 are joined.
