Storing Digital Data In 5 Dimensional Medium To Last 13.8 Billion Years And Longer

Online music services are awesome, because you can listen to music till your heart’s content.  There are many online music services out there, and I can name two right off the top of my head.  One is Spotify, and the other is Amazon music service.  Of course, online music services come in different forms, but the two I just named belong to a listen to all you want monthly/annually membership (i.e., subscription) category.  There are other forms such as online radio category.  iTunes’ music service does cater to both listen to all you want and online radio categories.

Whichever the form or forms an online music service does carry, our particular music library may go offline forever if a music service goes offline for good.  This means, some songs may never be heard again.  Of course, one can argue that many different online music services do store the same music library in their data centers, and so something this bad won’t happen.  Nonetheless, perhaps there are some unique music collections that would only be available for a particular online music service.  Such unique collections would be made unavailable forever if an online music service which carries these music collections is going out of business.

Music collection is just one among many various types of collections that we, as a civilization, should strive to safeguard for generations to come.  Yesterday data storage technology could not allow us to store data for an extended period of time, because the data storage medium would get deteriorated.  Then came along M-Disc which is still boasting that it could protect data for 1000 plus years.  Nonetheless, M-Disc is not efficient in term of capacity size, and each M-Disc could cost a lot.  What about the brand new 5D optical storage technology?

What about 5D optical storage technology?  According to the information under the YouTube video which showcases this technology, scientists from Optoelectronics Research Centre utilizes femtosecond laser writing technology to record data in 5 dimensional medium (i.e., nanostructured glass) which allows data capacity to expand to 360 TB and withstand up to 1000 Celsius degree.  The awesome part of this technology is that if data is stored at room temperature, along with the data, the data medium would last forever.  At 190 Celsius degree, along with the data, the data medium would last for 13.8 billion years.  If this technology becomes widespread, our data libraries would be able to last for the longest time.  This means we could preserve the digital parts of our civilization for untold amount of generations.
