ABSTRACT:
A wired flexure comprises a metallic substrate, a polyimide layer formed on the metallic substrate, and read conductors and write conductors formed on the polyimide layer. The polyimide layer has a thick-walled portion and a thin-walled portion that are different in thickness. The read and write conductors extend covering the thick- and thin-walled portions. In order to obtain a desired impedance, the width of the conductors in the thin-walled portion is smaller than that of the conductors in the thick-walled portion.
