An apparatus and method for enhancing data availability by leveraging primarybackup data storage volumes. The outer conductive coil extends through the lead body and is coupled to a first electrode at a distal end of the outer conductive coil. In the source gas supplying step, gas obtained by vaporizing an organic source is supplied to the substrate, and the gas thus supplied is allowed to be adsorbed on the substrate. This retractable pet leash is created by weaving or integrating reflective material fabrictape within a flat leash portion.
