Exemplary system, and computer program product embodiments for changing ownership of cartridges, such as virtual cartridges between remotely located virtual tape libraries, are provided. A gap between the resistive trace and the conductive trace is provided, and the conductive trace is either magneticferromagnetic or is provided with a magneticferromagnetic material. Therefore, the plate structure having a chip embedded therein can be processed by a simple method to achieve the tenacity of aluminum and the rigidity of aluminum oxide. The device may store a flag in each node that matches a step of the Xpath expression. , the reference value and a value corresponding to the output power of the laser diode, an APC operation is performed.
