A big problem with spinning disks is that storage grows inversely with the area of the dots, while reading and writing speed grow inversely with the diameter of the dots. If you store 100 times as much data, all else being equal, time to write a full disk will be ten times as large. Ways around that are increasing rotation speed (been there, done that. There is little to gain here without making the disk a lot strong…

Earlier quoted context omitted.

The real breakthrough would be a way for regular CD/DVD drives to at least be able to read the new format. But I doubt that this will be practical for consumers. Most consumers dont really need a CD drive anymore, companies like Apple arent even including them in laptops any longer.

I think CDs would make a comeback if you're talking about being able to hold an entire series of movies all in 4K and in 3D and not break a sweat. Digital downloads is all the rage right now, but people will still want to archive their downloads.

Seems a little past it's prime. Why would you want this when you have the internet?

Bandwidth. What if I could hand you the totality of Netflix, iTunes, etc.? Not wait for it to download, but transfer large chunks of the Internet in seconds? and no longer have to hope that, say, Netflix won't lose vast sections of their library for contractual reasons (as it has done of late)? Backups: permanent archiving of everything you have all on one disc. It makes vast swaths of data yours, in your hand, under…

Dr. Gan needs someone to introduce him to Kickstar…

Given Australia salary scales, this may be a typo, 180,000 would sound normal.
