Abstract: A wired flexure comprises a substrate formed of an electrically conductive material, a read wire provided on the substrate so as to extend along the substrate, a write wire provided on the substrate so as to extend along the read wire, a slit formed between the read and write wires, etc. The slit extends along the read and write wires and divides the substrate between a first portion on the read wire side and a second portion on the write wire side. The slit is situated nearer to the read wire than to the write wire.

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.

Abstract: A wiring portion has first and second write conductors, first and second read conductors, and an insulating layer. The first write conductor, first and second read conductors, and second write conductor are arranged three-dimensionally at different height levels in the thickness direction of the insulating layer, in a cross section extending in the width direction of the wiring portion. The distance from the first write conductor to the first read conductor is equal to the distance from the first write conductor to the second read conductor. The distance from the second write conductor to the first read conductor is equal to the distance from the second write conductor to the second read conductor.
