The development of optical memory devices that use violet laser diodes (LDs) has progressed significantly and these devices have been commercialized. The need for high-speed recording and multilayer recording is increasing, and it is expected that even higher power LDs will be necessary in the future. In this paper, the current state of GaN-based LD research for the next generation optical memory devices is reported, and next targets are discussed. Moreover, we developed high power pure blue laser diodes for full-color laser display. The details of these pure blue LDs characteristics are reported.
