ABSTRACT:
A method of limiting movement of a head suspension away from a disk surface, the head suspension used for supporting a head slider over the disk surface in a rigid disk drive, the method comprising the steps of providing a load beam for use in a head suspension, the load beam having a mounting region, a rigid region and a spring region located between the mounting region and rigid region; forming a shock limiter from the same piece of material as the spring region of the load beam, the shock limiter comprising a cantilevered portion overlapping an overlapped portion of the head suspension; forming a head suspension from the load beam; and mounting the head suspension in a bard disk drive suspending a head slider over the surface of the disk, such that when an impact load causes the head suspension to move away from the surface of the disk, the shock limiter limits such movement
