A lifetime of film can be stored on these new discs, which can record data in up to one hundred layers. The writing technology relies on two lasers, a 515-nm green laser that starts the dot formation – 0 or 1 bit – and a 639-nm red laser that stops it. The two together allow more information to be stored than ever before.
For nanoscale reading, a chemical called hexaphenylsilol (HPS) and a new material, AIE luminogens (AIEgens), were incorporated into the film. With the help of multilayer nanowriting, scientists were able to… More than 1 petabit of data stored on a single AIE-DDPR disc, which is the capacity of more than 5,000 Blu-ray discs.. To be commercially viable, writing speed must be improved and made more energy efficient. AIE-DDPR optical disks may revolutionize data storage in the future.
The study presented the new type of optical disc, capable of increasing information storage capacity to the petabit level, which means 125 terabytes of data, or the combined storage capacity of approximately 15,000 DVDs.'>
