ABSTRACT:
A hard disk drive includes a base, a head stack assembly (HSA) that is mounted to the base so as to be rotatable relative to the base, a voice coil motor (VCM) block that has an upper section and a lower section respectively disposed above and below a voice coil support of the HSA, and a crash stopper that limits the rotation of the HSA at the voice coil support. The upper section of the VCM block has a through-hole through which the crash stopper extends into a space between the upper and lower sections of the VCM block. The lower section of the VCM block has a groove in which the crash stopper is received. The hard disk drive can be assembled in a top down manner to allow the assembly process to be fully automated.
