  • Method for manufacturing magneto-resistive effect type magnetic heads
    Publication number: 20020066177
    Abstract: Providing a method for manufacturing magneto-resistive effect type magnetic heads which can suppress the electrostatic destructions due to the ESD and EOS, and can properly manufacture magneto-resistive effect type magnetic heads without deteriorating characteristics. In a layered type magnetic head forming step S1, a short circuit pattern for making a short circuit in the element circuit of an MR head is formed. And the short circuit pattern is cut off before a fine polishing step S4, or at a wafer bar cutting off step S6.
