In one embodiment, an apparatus includes a jitter generator configured to receive a reference clock; add jitter to the reference clock; and output the reference clock with the included jitter to a phase lock loop. The apparatus further includes a tilt measurement system for measuring the amount of relative inclination between the focusing optical system and the information recording medium and an offset application system for performing off-track of the light spot by applying an electric offset corresponding to the measured amount of inclination to the error signal. A method of moving a nanostructure includes controllably grasping, moving, and releasing the nanostructure with the molecular manipulator. An auxiliary strap may be connected to the stabilizing support device and used to keep the junctional and truncal tourniquet and the inflatable pressure application bladder in place on a patient’s torso.
