Holographic Storage Takes a Step Toward Viability

Facebook X LinkedIn Email
Aaron J. Hand

If holographic storage is ever going to make it out of the lab and really compete with existing data storage techniques, researchers must come up with practical, cost-effective solutions to some of the hurdles holography still faces. One such hurdle is volatility. Using polymers, researchers are able to fix information onto write-once, read-only holographic memories, but once they've made that data nondegradable, erasing or rewriting is impossible. On the flip side, lithium niobate has been shown to be a good material for rewritable holographic storage, but simply reading information from the...Read full article
