A method of reallocating data among physical disks corresponding to a logical disk is provided. The hierarchical structure of the XML document is saved separately in an XML skeleton object from which element data other than primary key values has been removed. 5 mm perpendicular to the optical axis of the laser component and in which the above named components are arranged. This may be when the reticle has been qualified by an optical test or when a die fabricated by reticle has passed an electrical test. The feedback regulator further comprises a first plurality of switches for selectively coupling a first terminal of the flyback capacitor between a low voltage and the output and a second plurality of switches for selectively coupling a second terminal of the flyback capacitor between a low voltage and the voltage comparator.
