Storing information in crystals

[Seeker of the One]

Ra talks about the crystals for healing. I have read The Lost Teachings of Atlantis, they state the information can be stored in crystals, some kind of crystal technology. How can you actually store this information in the clear quartz, for example? Any techniques available for consideration?

I am interested in practical means. Though you can provide some theory in order to how to do it practically. If you store the information in crystal then, how can you possibly take it out, to read the crystal looking for the information inside?
