摘要：

We have developed write/read technologies for post-Blu-ray Disc (BD) with a capacity of 50 GB/layer. In this report, the authors propose a crosstalk cancellation method that minimizes the error between the crosstalk canceled signal and the target signal that is generated from the binary output of an adaptive-partial response maximum likelihood (PRML) decoder. The experimental results obtained using our method show that the bit error rate is reduced to 1/100. A high-density recoding of 50 GB/layer was demonstrated using our method.
