以663 Gbits/inch<sup>2</sup>的原始数据记录密度进行121路复用记录。粗略估计，在12 cm光盘的记录面积为13.58英寸<sup>2</sup>（r=<sup>24258</sup> mm），使用码率为0.488的条件下，以663 Gbits/inch<sup>2的速率</sup>放置图书，12 cm光盘的数据容量为549 GB。663 Gbits/ inch<sup>2</sup> × 13.58inch<sup>2</sup> × 0.488 = 549 GB复用器（3）为了进一步提高复用记录性能，正在优化记录曝光时间、全息图间距和短堆叠<sup>[4]</sup>。这方面的进展也将在会议上报告。
A 121 multiplexed recording was performed at a raw data recording density of 663 Gbits/inch<sup>2</sup>. As a rough estimate, data capacity of 12cm disc becomes 549GB under the condition that books are laid at 663Gbits/inch<sup>2</sup> in the disc because recording area of 12cm disc is 13.58 inch<sup>2</sup> (r=24<sup>2</sup>58mm) and our using code rate is 0.488. 663Gbits / inch<sup>2</sup> × 13.58inch<sup>2</sup> × 0.488 = 549GB ⋅⋅⋅ (3) To further improve the multiplexed recording performance, the recording exposure times, the hologram spacing, and short stacking<sup>[4]</sup> are being optimized. Progress on this will also be reported at the conference.
