They've been dabbling with holographic optical disk storage for a while now. It'll still probably be 5 years or so until it hits consumer level.

true but i remember when DVD was coming out as a media only format.. saw it in a science publication and thought it was Tits...

The problem with holo storage is not the reading and writing.. i ts the erasing of data.

Nice thing about disk format is that its familiar, stretches the 3d layer thin and there is no need to erase it.

I remember reading somewhere that these used a 1W 532nm single longitudinal mode laser

you gotta be f-ing kidding me...

if your not pulling my leg then thats just gonna make green even cheaper...

[GooeyGus]

Nope!! Not pulling your leg... I cant remember where I read it but I will try to dig up the article...

Here's a post from April 2008, almost exactly one year ago...

Not new at all. In fact, I have a picture of one some where that doesnt need a spinning disk.

Four years ago a I pulled lasers off a prototype machine that wrote different layers with a multiline argon and read out with a red krypton while a disk was spining using a linear DMD and AOs. I didnt have a big enough truck at the time so I only got the lasers. Closed down startup in New Jersey. Scrappers had cleared out the building except for the prototype. I could only get the lasers, as the DMD was mounted in gold and the scrapper wanted it and the precision positioning stuff.

i have seen in person the holographic cubes. when i was on a special tour of apples facility in Reston Virginia, saw a 'next cube' there too... . single wavelength holographic storage or something similar is what they guys were calling it at the time. Thats back when they were working on ways to erase data. That has always been the issue, no way to erase.

Thats why they are looking at spinning disk media. no need to erase.

now i have also seen (not in person) the multi wavelength storage that promised to store a terabyte of data in an area the size of a standard 6 sided die.. that would be cool
