A novel optical data storage (ODS) system that relies on the optically‐induced switching of the aggregation state and fluorescence of a two‐photon absorption dye in a polymer matrix is reported. Well‐defined, ∼3 × 3 × 6 μm large voxels are written with single focused laser pulses and read by confocal laser scanning microscopy.
