Information recording

特許 権利維持 PROBLEM TO BE SOLVED: To increase the density of recording information by creating many complex wiring lines necessary for information recording density improvement and information access and reducing problems such as heat generation. ; SOLUTION: A vibration mode conversion element 3 and a detector 4 are arranged adjacently to the metal nano particles 2 of a sequence end, and the light of a light emitting element excites a local plasmon of a proximate field light in one particle of the vibration mode conversion element 3 by using a proximate field light probe 13.
