摘要:
A planographic printing plate material comprising a support and a light sensitive layer provided on the support, the light-sensitive layer being composed of (A) an inorganic material; (B) at least one metal and/or metal compound [(A)/(B) are capable of reacting with each other upon application of electromagnetic radiation] and (C) an organic compound capable of affecting the reaction between the inorganic material (A) and the metal and/or metal compound (B), wherein the inorganic material (A), the metal or metal compound (B), and the organic compound (C) are in contact with each other. When the light-sensitive layer is exposed to electromagnetic radiation, a difference in the hydrophilic or oleophilic nature of the exposed areas and the unexposed areas results, whereby a planographic printing plate is obtained which can be mounted on a printing machine and printed without any other treatments.

摘要:
A magneto-optical recording medium comprises a transparent substrate and a magneto-optical recording layer overlaid on the transparent substrate. The magneto-optical recording layer is formed by alternately overlaying a plurality of thin layers containing a rare earth metal-transition metal alloy for magneto-optical recording, and a plurality of thin layers containing at least one metal selected from the group consisting of gold, silver, lead, magnesium, copper, and iridium which are solid solution non-formable metals.
摘要:
In a vacuum, recording is conducted by exposing a solid surface to a neutral particle beam or an ion beam modulated with a recording signal and converged, thereby to locally develop a change in composition on the solid surface. Then, reproducing is conducted by exposing said solid surface to an electron beam, an ion beam or a neutral particle beam which has been converged, thereby to emit electrons from the solid surface, and detecting the emitted electrons to read out the change in composition. If necessary, erasing is conducted by exposing the solid surface to the same beam as used in reproducing, thereby to eliminate the change in composition.
