Abstract

In a head suspension, a gimbal spring is constituted by a flexible sheet having an electrical circuit formed on its surface, and a through hole is formed through that portion of a metal load beam overlying the gimbal spring. The load beam is bonded integrally to the gimbal spring to form the head suspension. There is also disclosed a rotary disk storage unit incorporating such a head suspension.
