• To clarify the potential of our $1\times$–$4\times$ speed dual layer Blu-ray disc recordable media (BD-R) in higher speed recordings, we evaluated the recording performance of each layer on over $4\times$ speed recording. The approaches are simulations and experimentations under the condition of 2T mark recordings at $4\times$, $6\times$, and $10\times$ speeds. As a result, we have successfully improved the speed dependence of dual layer BD-R by the write strategy. It is confirmed that the recording power ratio $P_{\text{s}}/P_{\text{w}}$, where $P_{\text{s}}$ is the space power and $P_{\text{w}}$ is the peak write power, is one of the key parameters for achieving high-speed recording. It is expected that our dual layer BD-R could cover $1\times$–$10\times$ speeds.
