ABSTRACT:
A ramp is disclosed for use in a disc drive system for loading and unloading a magnetic slider carrying actuator. The actuator is rotatable about an actuator pivot and supports the magnetic slider over a first surface of a magnetic disc. The ramp includes a pivoting arm which rotates about a ramp pivot such that the pivoting arm moves toward an inner diameter of the first magnetic disc surface as the actuator rotates toward an outer diameter of the first magnetic disc surface during unloading of the actuator. A sloped region coupled to the pivoting arm is adapted for receiving the actuator during unloading as the pivoting arm moves toward the inner diameter and as the actuator moves toward the outer diameter.
