Abstract:
1. A wiring member for a suspension for a disc drive, wherein the suspension comprises a base section, a load beam section, and a flexure extending along the load beam section, said wiring member comprising: a metallic substrate; an electrical insulating layer which is formed on the metallic substrate, and which includes a thick-walled portion and a thin-walled portion which are different in thickness; and read conductors and write conductors formed on the insulating layer such that a part of the each of the conductors extends over the thick-walled portion of the insulating film and a part of each of the conductors extends over the thin-walled portion of the insulating layer; a close wiring portion in which the read conductors and the write conductors are provided close together and in parallel; and a rough wiring portion in which the read conductors are farther apart from the write conductors than in the close wiring portion; wherein the thin-walled portion of the insulating layer is provided in the close wiring portion; and wherein a space effective for reduction of cross talk is provided between the read conductors and the write conductors, such that a width the part of at least one of the conductors over the thin-walled portion is smaller than a width of the part of each of the conductors over the thick-walled portion.
