Title:
WINDOW, MEDIUM AND OPTICAL STORAGE METHOD
Document Type and Number:
WIPO Patent Application WO/2020/233666
Kind Code:
A1
Abstract:
Provided by the present invention are a window, a medium, and an optical storage method; the window comprises a polymer solid film layer; light absorption controllable interchanging molecules are comprised in the material of the window, and the light absorption controllable interchanging molecules are converted between molecules having a first configuration and molecules having a second configuration; the absorption rate of first light of the molecules having the first configuration is lower than the absorption rate of second light thereof, and the absorption rate of second light of the molecules having the second configuration is lower than the absorption rate of first light thereof; and when the molecules having the first configuration absorb the second light but do not absorb the first light, the molecules having the first configuration are converted into the molecules having the second configuration; and when the molecules having the second configuration absorb the first light but do not absorb the second light, the molecules having the second configuration are converted to the molecules having the first configuration. The medium comprises a window and a light sensitive portion. The present invention adopts the principle of dual-beam super-resolution optics, achieves a super-resolution high-density technology in combination with a window, and solves the problem in the existing dual-beam technology wherein requirements on the material of a light sensitive portion are high.
