PURPOSE:To eliminate the damage of passivation by working preliminarily the passivation of a magnetic head to the slider shape of the magnetic head by a method such as etching or mask sputtering. CONSTITUTION:The passivation 3 formed on a protective film 2 of a substrate 1 is worked by etching, mask sputtering, etc. to the slider shape of the magnetic head and the other parts 4 are removed by machining such as cutting, grinding or polishing to assure the working accuracy of a ski surface 5 and gap depth. Since the passivation 3 is preliminarily worked to the slider shape, the head is produced simply by machining the part 4. The passivation damage is thus eliminated. |
