Abstract

See full text

A thick portion having a first thickness and a thin portion having a second thickness on a base insulating layer are formed on a conductive support substrate. The second thickness is smaller than the first thickness. A boundary surface is formed between an upper surface of the thick portion and an upper surface of the thin portion. A boundary line between the upper surface of the thick portion and the boundary surface extends in a first direction. Write wiring traces and read wiring traces are formed to extend on the thick portion and the thin portion of the base insulating layer. The lateral sides of the write wiring traces and the read wiring traces extend in a second direction that intersects with the first direction, and the second direction forms an angle of not less than 60 degrees and not more than 90 degrees with the first direction.
