Patent ID: 7692899

Claim:
A head suspension comprising: a load beam configured to apply load to a head ha writes and reads data to and from a hard disk; a flexure made of a conductive chin plate substrate attached to the load beam and configured to support the head; base layers made of flexible resin and formed on the plate substrate of the flexure; write wires and read wires having first ends connected to the head and second ends distal to the head and located at the load beam, the write wires and the read wires from the first ends to the second ends being formed on the base layers, said base layers having sufficient insulating characteristics between the write wires and the conductive thin plate substrate of the flexure and also the read wires and the conductive thin plate substrate of the flexure so as to permit functional transmission of read and write signal from and to the head; the base layers including a write-wire-side base layer and a read-wire-side base layer disposed apart from each other, the write-wire-side base layer being disposed between the write wires and the conductive thin plate substrate of the flexure and the read-wire-side base layer disposed between the read wires and the conductive thin plate substrate of the flexure; and at least a portion of the read-wire-side base layer of the flexible resin of the base layers at least at a position between the first ends and the second ends, being a slightly conductive flexible resin at least between the read wires and the flexure so as to discharge static electricity from at least the read wires to the conductive thin plate substrate of the flexure.
