Brad BoimlerNext-gen optical disk can store over 14,000 4k movies
RegalPotoo1.4Pb (~175TB), the quoted number of movies is based on a 14GB movie which is very small (most BluRay disks hold somewhere between 25 and 50GB) and no discussion about write speed, so basically this is cool research that someone has done and is no closer to a commercial product that any of the dozens of other articles that have come out on this topic in the last 15 years
evilsmurfFrom the article:
What’s almost more remarkable is that the scientists say a single new blank disc can be manufactured using conventional DVD mass production techniques within six minutes.
If this was a response to write speeds they meant the speed at which data can be written to the disc, not the time ot takes to build the disc.
Read/Write speeds are a standard measure used to tell whether something would be efficient to use. For example one could say storing an OS on a DVD and booting would be dumb because it would run extremely slow, where as the read speed for playing music or a movie off it wouldn’t be an issue as it doesn’t need higher performance for such.
