Abstract:
1. A suspension substrate extending from a head portion having a slider mounting area, to a tail portion with which an external connection substrate can be connected, the suspension substrate having a linear longitudinal axis passing through the center of the slider mounting area, the suspension substrate comprising: an insulating layer; a spring material layer provided on one face of the insulating layer, the spring material layer having conductivity; and a plurality of writing and reading wirings, respectively provided on the other face of the insulating layer, wherein one wiring of the plurality of writing wirings includes a head-side wiring part extending from the head portion and a plurality of division wiring parts, respectively bifurcated from the head-side wiring part, wherein the spring material layer includes a spring-material-layer main body, and a first spring-material-layer separated body and a second spring-material-layer separated body, respectively separated from the spring-material-layer main body as well as separated from each other, wherein a pair of conductive connection parts are provided to extend through the insulating layer, wherein one division wiring part of said one wiring is connected with the first spring-material-layer separated body, via one of the conductive connection parts, while the other one of the division wiring parts is connected with the first spring-material-layer separated body via the other conductive connection part, and wherein the first spring-material-layer separated body is located on one side relative to the longitudinal axis, while the second spring-material-layer separated body is located on the other side relative to the longitudinal axis.
