Abstract
A power loss retraction architecture is provided to retract the VCM arm of a hard disk drive upon power loss. The power loss retraction architecture is configurable to be able to use energy from different sources. The selected energy source is used efficiently by applying the energy only to the VCM retract arrangement, while isolating the energy source from other circuits that are not needed to accomplish the retraction operation.
