An optical information recording medium of the present invention includes at least one information layer. These compounds are applicable to a variety of research areas such as quantum computing, metabolism and materials science. The playing surface is formed by the thus widened upper side of the base body lying horizontally in the playing position. The load port interface is connected to the casing for loading substrates into the processing device. If a processing node, other than the source and the target nodes, finds a modified cached copy of the designated memory location, that processing node responds with a memory cancel response sent to the target node and a read response sent to the source node. Metallic structures on the device are also protected from galvanic attack because they are protected from contact with HF or HCL-bearing solutions.
