摘要： Embodiments disclose hole sequences that are formed in the metal layer of a trace to adjust rigidity and crosstalk noise resulting from the hole sequences is thereby suppressed. A suspension according to one aspect of the invention includes a trace adapted to transmit a signal of a head slider. The trace partially extends along the side surface of the suspension. The trace includes a metal layer, a plurality of transmission lines formed above the metal layer and an insulating layer. A hole sequence overlapping the transmission lines is formed in part of the metal layer, which contributes to a reduction in transmission loss. Another hole sequence of the metal layer is formed at a position opposed to the hinge portion of the suspension. This reduces the rigidity of the wiring structure portion in the hinge portion, thereby preventing interference with the behavior of the suspension at the hinge portion.

摘要： Embodiments in accordance with the present invention disclose hole sequences that are formed in the metal layer of a trace to adjust rigidity and crosstalk noise resulting from the hole sequences is thereby suppressed.

A hole sequence overlapping the transmission lines is formed in part of the metal layer, which contributes to a reduction in transmission loss.
