    摘要： Even if sizes of storage cells are reduced in a phase change memory, properties of the respective storage cells can be set to be approximately equal to one another and a current amount required for phase change can be reduced sufficiently. The phase change memory includes at least a storage cell. The storage cell includes a first electrode, an electrically conductive portion provided on the first electrode and having at least two electrically conductive bodies with approximately the same shape provided on the first electrode, the electrically conductive bodies being spaced by a high resistance film with a high resistance, a recording layer provided on the electrically conductive portion and having phase change material which can change between a first phase state with a first specific resistance and a second phase state with a second specific resistance different from the first specific resistance, and a second electrode provided on the recording layer.

    摘要： A recording apparatus for holographic recording medium having an alignment mark and designed to irradiate a recording light beam onto a recording region of holographic recording medium to record information as a hologram. This apparatus comprises a recording laser recording the hologram onto the medium, an alignment laser irradiating an alignment light beam onto the medium, the alignment light beam being less absorbed than the recording light beam by the medium, and being reflected by the medium, a first lens converging the recording light beam and directing it toward the medium, a second lens converging the alignment light beam and directing it toward the medium, a photodetector detecting a light intensity of the alignment light beam reflected from the medium to recognize the alignment mark, and a driving mechanism adjusting a region to be irradiated with the recording light beam relative to the medium based on the alignment mark.
