Do you mean life wise?

Yup. And ones that don't have defects.

No, forget that. The next 'Nature Journal' reported innovation will be
electrodes directly interfacing computers with the real organic brains
of an animal bred specifically for having a long term memory. Er, how
many classical concert recordings could be stored in an elephant?

The trouble is that the more you cram into less room, the more fragile
it all gets. It is starting to approach the point at which random
quantum tunnelling events and the like can change the state of a bit
here and there. So discs like this will need higher levels of error
correction than less dense ones. This will inevitably compromise read
and write speed.

And the idea of making it removable (hence handleable) just has to be
wrong. Remember the early days of the CD ROM, when you had to put the
thing in a caddy before it went in the drive?

It was only a year or two since we were handling double sided Panasonic
DVD-RAM disks (4.7 Gb?) that never left their caddy, but now I'm handling
'nude' 25 and 50 Gig BD-REDL disks on a daily basis - the technology rises
to match the technology (IYSWIM) - scratchproof layers...

If you want summat to nag away at your brain - think of the *2.1 MILLION*
mirrors on a 1080p DMMD chip twinkling away all the while you watch the
latest blockbuster:

Bothers me - I'd sooner not be reminded of it....

Great video but I find the colour wheel thingy harder to get my head
around than the chip. The video makes it look very crude indeed.

You mean how much it's going to irritate when just one of them sticks.

Yep, for all its 21C technology, I still think it's all a bit *Logie
Baird*..!!

The answer of course is 3 (dedicated RGB) DMD chips but that wouldn't be
cheap and there's not even too many movie theatres with that technology
yet - according to my 'digital source'! (Oldest son!)

We've gone full circle - back to the Baird scanning system...

Knock on wood, we've got two 720p PJs on the go with about 900,000 mirrors
on the chips and no sign of any failure yet...??

(And I suspect they'd be out of warranty now, or headed that way!)
