A small-sized and thin flexible recording system including a flexible disk drive and a recording disk is provided. For example, the method receives capacity data and user equipment resource consumption data from a plurality of devices that process call control signaling messages within the communication network. Accordingly, the projection system adopting an image display device as a liquid crystal device provides a remarkably enhanced contrast enhancement effect. The rate of MFD expansion of the first fiber is less than the rate of MFD expansion of the second fiber during the fusion splicing operation.
