Magnetic head suspension assembly having flexible wiring member with connection terminal including center hole and cover layer and disk device provided with the same

A magnetic head suspension assembly, comprising:

• a support plate coupled to a magnetic head, and
• a flexible wiring member disposed on the support plate, wherein the flexible wiring member includes a tip portion disposed on the support plate and a connection end portion disposed at an opposite end of the flexible wiring member from the tip portion,
• the flexible wiring member further including a metal plate fixed to the support plate, an insulating layer disposed on the metal plate, a conductive layer which is disposed on the insulating layer and forms a plurality of conductive lines and a plurality of connection terminals, and a cover layer that is disposed on the conductive layer and includes an electrically insulative material,
• the connection end portion including the plurality of connection terminals formed from the conductive layer, and
• each of the plurality of connection terminals including a center hole, a first terminal surface that is a surface of the conductive layer and has a plurality of discontinuous portions of the cover layer formed thereon, and a second terminal surface that is a surface of the conductive layer and faces away from the first terminal surface.

A disk device comprising:

• a disk-shaped recording medium having a magnetic recording layer,
• a carriage assembly with a plurality of connection pads formed thereon, and
• a magnetic head suspension assembly that is mounted on the carriage assembly and includes a support plate coupled to a magnetic head, and a flexible wiring member disposed on the support plate, wherein the flexible wiring member includes a tip portion disposed on the support plate and a connection end portion disposed at an opposite end of the flexible wiring member from the tip portion,
• the flexible wiring member further including a metal plate fixed to the support plate, an insulating layer disposed on the metal plate, a conductive layer which is disposed on the insulating layer and forms a plurality of conductive lines and a plurality of connection terminals, and a cover layer that is disposed on the conductive layer and includes an electrically insulative material,
