Abstract:
A method for manufacturing a slider having a first surface to serve as a flying surface, a second surface formed in a position at a predetermined first depth relative to said first surface, a third surface formed in a position at a predetermined second depth relative to said first surface greater than said first depth, and a side surface connecting said first surface and said third surface, the side surface having no step, the method comprising the steps of:forming a first etching mask on a region of the material of the slider to become said first surface;etching said material to said first depth using said first etching mask to form said second surface;forming a second etching mask at least on a region of said material to become said second surface excluding a region to become said third surface without removing said first etching mask;etching said material further using said first and second etching masks by an amount corresponding to the difference between said second and first depths to form said third surface; andremoving said first and second etching masks from said material.
