A virtual data storage system stores data as data objects to a plurality of storage devices in accordance with storage management policies. A file systems stored on different data partitions and, of different operating systems and, running on a multi-host computing system may be shared based on file server-client architecture. In addition, the Bernoulli end effector may be used to place ultra-thin substrates on and retrieve substrates from a substrate handling structure that includes weights that prevent the substrates from bowing or flexing during processing and includes guides that prevent the ultra-thin substrates from moving or translating on the surface of the substrate handling structure. The resulting measurement signal, which is dependent on the distance between the measuring device and the workpiece, is used to detect the degree of transformation. Further, the steps for forming the thermal recording material by coating and drying the respective coating liquids for forming each layer that are characterized in that the drying process of the intermediate layer is performed while controlling wet membrane surface temperature at no higher than 35\xb0 C. 1 wt % and 5 wt % of a perfume andbetween 0.
