PURPOSE:To perform the highly accurate magnetic head grinding by grinding a magnetic head to the predetermined dimension through a fixed dimension device then retreating said device and eliminating the defect on the grinding face due to a measuring chip through the micro-cut grinding. CONSTITUTION:The traverse grinding is performed by arranging a plurality of magnetic heads and rolling by means of a grindstone wheel. Upon completion of the grinding to the predetermined dimension by means of a fixed dimension device, said device is retreated and the defect on the grinding face due to the contact with a measuring chip. Since the cutting amount for grinding the defect is constant, the fixed dimension device is functioned by the dimension added with said constant dimension. In such a manner highly accurate and defectless grinding face of a magnetic head can be obtained. |
