The invention relates to three-dimensional optical memory devices and can be used in all areas of computing in which it is necessary to record large data files on compact carriers. The silica is preferably present in an amount of 15 to 30% by weight of the total dry weight of silica and PCC. Separation of fluid flow into 2 streams engages the wheels for rotation in opposite directions. The embedded sections are arranged in a desired pattern of voids, and each embedded section has a top surface below the planarizing surface to define a plurality of voids in the base section. The CLD management system retrieves the requested label data from the database and communicates the label data to an output device for printing a new vehicle label for use by the repair shop.
