Thinnest Light Disk In article number 2103140, Hongwei Liu, Junpeng Lu, Yunfei Chen, Zhenhua Ni, and co‐workers present the thinnest light disk with an encryption functionality based on WS 2 monolayers. The writing‐in and reading‐out of information are enabled by directly controlling the fluorescence contrast of the WS 2 monolayers. The writing speed can be up to ≈6.25 MB s −1 , while the data storage density can reach ≈62.5 MB cm −2 within the thickness of <1 nm.
