Abstract

A data storage device includes at least one head supported by an actuator arm. The at least one head interacts with the at least one data storage disc when positioned over the at least one data storage disc. The data storage device further includes a split ramp for supporting the at least one head when the at least one head is moved away from the at least one data storage disc. The split ramp has a first ramp portion adjacent to a first outer diameter (OD) of the at least one data storage disc and a second ramp portion adjacent to the first ramp portion, such that the first ramp portion is between the second ramp portion and the first OD. At least one of the first ramp portion or the second ramp portion is independently moveable.
