In a recording material, physical characteristic information of the recording medium, and more specifically, material information representing the material of the disc, is recorded. In one aspect, a respective motion map is computed for each pairing of a reference image and a respective image neighboring the reference image in a sequence of base images. 1 to 3 parts by weight of an internal mold release agent and 0. Each one of the common electrode control units generates a first output signal and a second output signal opposite to the first output signal according to the former common electrode controlling unit and two adjacent scan lines. A lock state is maintained in the lock metadata in the shared storage. Because model entities may share a predefined relationship, embodiments of the invention allow for users to specify query criteria applied against related instances.
