“…This write strategy appears very well suited for CAV recording, as it requires only a simple linear tuning of the power settings. Special recording electronics 1) or adapted write strategies, 2) as have been found necessary for phase-change based BD-R recording, are not required for CuSi discs in order to achieve bottom jitters less than the specified 6.5% at 7Â recording.…”

A Cu/Si bilayer can be applied as the recording medium in a write-once Blu-ray Disc (BD-R). Recording experiments performed on BD-R stacks showed that a 1/1 ratio of Cu/Si layers prove to have the best recording results. Auger analysis points to a diffusion-driven process, primarily that of Si into Cu. By optimization of the stack, we have been able to record 1–7× BD-R 25 GB discs with bottom jitters below 6.5% using a castle-type write strategy.

“…Minemura et al recently reported on a phasechange based write-once BD that can achieve write/read speeds up to 9Â. 1) The nature of the recording material or the stack composition has not been specified. Although they used specifically designed recording electronics, the jitter values are far beyond the specified value of 6.5%.…”
