Data recording apparatus and method using 3D optical memory, and authentication apparatus and method using 3D optical memory |
摘要 |
Disclosed herein are a data recording apparatus and method using three dimensional (3D) optical memory and an authentication apparatus and method using 3D optical memory. The data recording apparatus includes a recording excitation light splitting unit, a condition storage unit, and a data recording unit. The recording excitation light splitting unit splits recording excitation light into first split light and second split light. The condition storage unit stores recording conditions including information about the waveforms, wavelengths and phases of the split light and information about an arrangement of reflection mirrors configured to reflect the split light. The data recording unit records storage data by making the split light incident on the 3D optical memory through the reflection mirrors under the recording conditions. |
