摘要： A novel head stack assembly (HSA) is disclosed and claimed. The HSA includes an actuator including an actuator body and an actuator arm extending from the actuator body, and a flexible printed circuit (FPC) adjacent the actuator body. The FPC includes a slit therethrough. A head gimbal assembly (HGA) is attached to the actuator arm. The HGA includes a load beam, a laminated flexure attached to the load beam, and a head attached to the laminated flexure. The laminated flexure has a flexure tail that includes an intermediate region that is disposed adjacent the actuator arm, and a terminal region that is electrically connected to the FPC. The terminal region is substantially orthogonal to the intermediate region. The intermediate region of the flexure tail extends into the slit, interferes with the slit, and contacts and deforms the FPC adjacent the slit.
