Holographic data storage?

[meatballofall]

My grandpa told me that he read an article in the new york times that talked about "holographic" hard drives. He said it could hold data that was burned into a 3d medium.... did anyone see this article? I want to know more about it... could mean more high power laser diodes on the rise. Maybe something that would work like a dual layer writer.... except with 20 layer capabilities.

yeah, it's been done. The only problem is erasing the data  I'm pretty sure it uses high powered green lasers for reading though.

Didn't it use like a 1 watt green laser or something? I remember some optical disc drive was going to have a 1 watt greenie, and I think a 1 watt red too.

I say get it into development, they would be hobbyist heaven
