摘要： The present invention includes a flexible printed circuit bracket including a crash stop rubber and/or an air block. The air block directs the air flow from the rotating disk surface(s) away from the head gimbal assemblies to minimize positional variance of the read-write heads. The crash stop rubber contacts the crash stop stub on the actuator arm block, stopping actuator assembly swinging away from the disk. The invention includes making an actuator assembly with the invention's flexible printed circuit bracket, as well as making the hard disk drive. The invention includes both the actuator assembly and the hard disk drive as the products of these processes. The invention also includes the actuator assembly and the hard disk drive containing the invention's flexible printed circuit bracket.
