A gas barrier packaging laminate having durability to stress crack formation and yet a bending stiffness and good integrity between the laminate layers, includes outer layers of heat-sealable polyolefin, two polymer carrier layers each being coated with a SiOx gas barrier layer, and an intermediate polymer layer that includes at least first and second part-layers. Each edge of the mounting plate has a mounting interface. In an alternate embodiment, a print head is radially mounted in a fixed position over an optical recording drive such that said drive moves as a sled under the print head for dispensing ink object along a radius as the media spins, affecting recording and labeling the media in a single insertion of the media. The surface area of the X-shaped portion has a generally concave curvature, whereas the surface areas of the sections 11 have convex configurations in relation to the concave surface area of the X-shaped portion. The melter assembly may comprise the refractory assembly and the at least one power transfer element connected to the refractory assembly. The other CoMn\u03b1 sublayer is in contact with upper nonmagnetic material layer.
