This paper describes magnetic properties, recording characteristics and noise properties of metal evaporated (ME) tapes, especially for multilayer structures. Also the future potential of recording characteristics of ME tape is studied by a simulation method.

Under the JST-ERATO project in progress to develop X-ray and neutron phase-imaging methods together, recent achievements have been selected and reviewed after describing the merit and the principle of the phase imaging method. For X-ray phase imaging, recent developments of four-dimensional phase tomography and phase microscopy at SPring-8, Japan are mainly presented. For neutron phase imaging, an approach in combination with the time-of-flight method developed at J-PARC, Japan is described with the description of new Gd grating fabrication.
