A performance comparison between a rate 8 / 14 asymmetrical run-length-limited (RLL) code and the EFMPlus code for optical disks is described. The limited condition of the rate 8 / 14 asymmetrical code is. This code has a better detection window size than the EFMPlus code because of the 14.3 percent greater efficiency of its coding rate. We describe the bit error rate (BER) performance and the tilt and defocus tolerance of the rate 8 / 14 ARL code. Compared to the EFMPlus code, the rate 8 / 14 ARL code has a 0.7-dB gain in the required S / N at a BER of 10-4. The rate 8 / 14 ARL code is also more robust against tilt and defocus.
