Abstract
A head suspension prevents a read element from electrostatic discharge damage without employing a static electricity remover, and at the same time, secures the frequency characteristics of a write signal. The head suspension has a load beam to apply load to a slider that writes and reads data to and from a hard disk, a flexture made of a conductive thin plate attached to the load beam, to support the slider, write wires connected to the slider and formed on an insulating base layer that is made of flexible resin and is formed on the flexure, and coating made of conductive flexible resin to discharge static electricity. The coating is formed over the read wires and is extended to the surface of the flexure.
