Abstract

PURPOSE:To prevent the damage due to a contact of a recording medium for a magnetic circuit wound by a conductor, by adhering a protective matter with an electrostatic process to a magnetic head made of a thin film magnetic material. CONSTITUTION:A protective matter 1 is directly adhered with an electrostatic process to a substrate 5 containing a thin film magnetic head 4. First, the adhering surface of the matter 1 composed of silicon, titanium, aluminum, etc. is smoothed, and a groove 2 is cut on the smoothed surface. Then the glass 3 having a low melting point is accumulated on the bottom of the groove 2 to secure a depth of (d). On the other hand, a magnetic thin film, a conductor thin film and an insulator thin film are laminated on the substrate 5 with a height of 5-20mum to form a magnetic head 4. The substrate 5 is stuck on the matter 1 so that the head 4 is put into the groove 2 of the matter 1, and preheating is carried out at 300-350 deg.C to soften the glass 3. Then the high voltage of a prescribed polarity is applied to both the matter 1 and the substrate 5, and accordingly, the electrostatic adhesion progresses. The glass 3 is pressed to the head 4 and deformed as shown in figure E. The substrate 5 uses silicate containing several % of lithium. As a result, the damage of the substrate 5 which is caused by the friction with a recording medium can be avoided.
