From the video

Answers: Are CDs making a comeback and what is the new petabit CD technology?

• history of compact discs
• 3D optical data storage
• petabit capacity optical discs
• data center storage technology
• limitations of physical media storage

What it concludes

• Researchers developed a 3D optical disc with a storage capacity of 1.6 petabits.
• The new optical disc technology uses ultra-transparent materials and nanoscale spots smaller than the wavelength of visible light to achieve high-density storage across 100 layers.
• While the new optical disc offers massive storage capacity suitable for data centers, manufacturing and adoption face severe limitations including high energy consumption, slow writing speeds, and expensive laser equipment.
