1. A magnetic storage device, comprising:
a magnetic disk;
a carriage arm rotatably movable relative to the magnetic disk;
a suspension arm co-movably fixed to the carriage arm, wherein the suspension arm comprises:
a slider attachment side; and
at least one first electrical contact pad on the slider attachment side;
a slider co-movably fixed to the suspension arm, wherein the slider comprises:
a base having a suspension attachment side, a non-head side facing the suspension arm and intersecting the suspension attachment side at a first slider edge of the base, and a head side opposite the non-head side and facing away from the suspension arm, wherein the suspension attachment side extends between the non-head side and the head side of the base; and
at least one second electrical contact pad attached to the suspension attachment side of the base, and comprising:
a first portion on the suspension attachment side of the base; and
a second portion protruding from the first portion away from the suspension attachment side at an angle with respect to the first portion, and having a maximum width, in a virtual plane substantially parallel to the suspension attachment side, wherein the maximum width of the second portion is less than a maximum width of the first portion in the virtual plane;
at least one solder weldment directly coupled to the at least one first electrical contact pad and the at least one second electrical contact pad; and
a read-write head coupled to the head side of the base.
