Abstract
A ramp loading and unloading system for the heads in a disc drive including an integrated latching mechanism for the disc drive actuator. The flexures that support the heads include ramp contact features which engage the ramps, and at least one of the ramp contact features includes a vertical latching face. At least one of the ramps includes a discontinuity forming a ramp latching face with which the vertical latching face of the ramp contact feature engages to latch the actuator. The ramp structure also includes a pivoting member which is rotated under influence of the actuator to allow the latching faces of the flexure and ramp structure to disengage.
