ABSTRACT:
An improved limit stop system for defining the extremes of the range of motion of the actuator of a disc drive. An elongated slot having inner and outer contact surfaces is provided in the bobbin inside the coil of the actuator voice coil motor. A pin member having a compliant portion is assembled through the elongated slot in the coil bobbin and into engagement with stationary components of the disc drive. When the intended extreme of the range of motion of the actuator is reached, either the inner or outer contact surface of the elongated slot contacts the compliant portion of the pin member preventing further motion of the actuator in that direction.
