Abstract
A system to detect a ramp position is disclosed. The system includes a head positioner coupled to an actuator arm to position a head relative to a disk and a controller to: control the head positioner to move the head toward the ramp; determine a plurality of integrator values while moving the head; generate a threshold based on the plurality of integrator values; and determine the ramp position based on a first integrator value exceeding the threshold.
