Embodiments of the invention are directed to systems, methods and computer program products for splitting a gift card. The image recording apparatus includes the above exposure head an optical system for focusing on a predetermined position the light emitted from the exposure head and a scanner for allowing the exposure head and a photosensitive material to move relatively, while regulating the photosensitive material at the predetermined position. A first set of transformed voltages and transformed currents are produced. Furthermore, the method maintains access statistics for each of the data items, an age of each of the data items, and an administrator-defined importance value of each of the data items. A first current source and the second current source are coupled to the second node and the third node respectively, and a reference current source is coupled to the first node.
