The present invention provides an information recording medium with high reliability and excellent repeated rewriting performance even when no interface layer is formed and a method for manufacturing the same. The tool will trace the path of each tire and allow an investigator to accurately produce a drawing to recreate the path of vehicles involved in accidents. Preferably, the packaged fluid receptacles are cuvettes usable in a clinical analyzer.
