| 摘要 |
The present invention provides a method of recording information on a memory medium and reading the information, comprising the steps of forming a reflective or transmissive surface having an anisotropic microstructure on a substrate of the memory medium to record information in the microstructure, entering light onto the reflective or transmissive surface, and detecting change in the polarization or intensity of a reflected or transmitted light caused by the microstructure, to read the information. The present invention also provides a memory medium, a production method thereof, and an information reading system.
