MANUFACTURE OF MAGNETIC HEAD AND GRINDING HOLDER

PURPOSE:To attain simultaneous grinding of many magnetic heads by providing a spring having a projection to depress the rear face center of a magnetic head slider being accommodated for supporting the magnetic heads. CONSTITUTION:A support plate 11 accommodating and supporting many magnetic head sliders 10, a spring plate 15 with many springs 14 pressing the magnetic head sliders 10 onto a grinding face plate 13 formed thereto, a pressing plate 17 having the spring plate 15 with respect to the support plate 11, a weight holder 18 placed on the pressing plate 17 and a weight 19 placed on the weight holder 18 are employed for the manufacture. Then the magnetic head holders 10 are supported by the support plate 11 to expose the slider face and pressed on the grinding face plate 13 with the springs 14 to lap the slider face. Thus, the magnetic head grinding is implemented at high efficiency to eliminate a personal error in the grinding, and the production of the magnetic heads is implemented with high reliability.
