在我们的1.84数值孔径(NA)的固体浸没透镜记录系统中，在高于100Gbit/in.2的记录密度下测试了信号特性。与以前的结果相比，低密度奇偶校验编码的部分响应(PR)17奇偶保留/禁止(PP)系统将记录密度提高了约35%。当记录密度为109Gbit/in2时，记录功率容差为±8.1%。我们得出的结论是，记录密度的上限为109Gbit/in2，假设与蓝光盘格式的冗余相同，这相当于12厘米直径的盘的151Gb字节。
The signal properties were examined at recording densities higher than 100 Gbit/in.2 in our solid immersion lens recording system of 1.84 numerical aperture (NA). The low-density parity-check coded partial-response (PR) 17-parity preserve/prohibit (PP) system increased the recording density by approximately 35% compared with the previous results. The recording power tolerance was ±8.1% at a recording density of 109 Gbit/in.2. We conclude that the upper limit of recording density is 109 Gbit/in.2, which is equivalent to 151 Gbytes for a 12-cm-diameter disc, assuming the same redundancy as that of the Blu-ray disc format.
