Abstract

A disc drive includes a disc, a voice coil motor with an arm and a beam having a first end attached to the arm and a second end including a window frame and a gimbal region. A bridge of a gimbal strut underlies the gimbal region. A flex circuit is attached to the gimbal strut. A read/write head has a preload region under the bridge and a slider surface on the disc. A microactuator has a main body and has microactuator arms bonded to the read/write head and mount arms bonded to the bridge. The microactuator has electrical contacts connected to the flex circuit. The electrical contacts are disposed between the microactuator main body and the gimbal region.
