HOLOGRAPHIC STORAGE MEDIUM, METHOD OF MANUFACTURING A HOLOGRAPHIC STORAGE MEDIUM AND METHOD OF READING DATA FROM A HOLOGRAPHIC STORAGE MEDIUM

摘要

The present invention relates to a holographic storage medium (10) comprising a recording medium (12) sandwiched between a substrate layer (14) and a super-strate layer (16), and a regular spacer arrangement (18) provided in the recording medium having optical properties different from optical properties of the recording medium, wherein the regular spacer arrangement defines atleast one location in the recording medium that can be used for retrieving a position of at least one data set (24) stored in the recording medium. The present invention further relates to a method of manufacturing a holographic storage medium and to a method of reading data from a holographic storage medium. Fig. 3
