NEC ND-4551A - LabelFlash Technology
 

Almost right after the launch of the flagship DVD recorder NEC ND-4550, there appeared an interesting modification of this model, called ND-4551. Similar modifications were made to the ND-3550, which got the name ND-3551. What's this modification about? If you expect hardware changes, I'm afraid I'll disappoint you: 4550 and 4551 models are absolutely identical inside; all changes come down to firmware. If you keep tabs on the optical storage news, you may have noticed the curious Lightscribe technology that allows to use a standard laser to draw high-quality labels on CD/DVD with special coating. But NEC didn't license this technology and developed its own, similar, but more interesting technology, called LabelFlash. As we found no other differences in specifications of the new ND-4551 versus ND-4550, the main interest to the new model may be directed only at the new labeling technology
