New Method for Adjusting Write Strategy using Sequenced Amplitude Margin


English / Japanese



Abstract:

We proposed a new method for adjusting write strategy in partial response maximum likelihood systems. It utilizes novel indices calculated from sequenced amplitude margin and produces both a low bit error rate and a wide recording power margin.

Keywords:

optical disk, PRML, bit error rate, recording power margin, sequenced amplitude margin, write strategy
