In this paper recent high speed recording results are presented for Blu-ray Disc CuSi recording. An optical pulse timing scheme is discussed based on power controlled transitions (PCT), using the physics and dynamics of the semiconductor lasers. The applied PCT scheme allows for a timing resolution in the 10 ps range and does not require special ultra-high speed electronics, making it a very suitable candidate for future drive implementation. In this way high speed recording experiments became feasible with recording speeds up to $12\times$. The recording material CuSi has proven to be a good candidate for high speed Blu-ray Disc recording, without the need for complex write strategies.
