since there's no forums on here I wanted to know if one could have data printed on metal so that one could have long term data storage of there precious ring...data.
I know I would pay for something like in the process of printed cd/dvd there is an etched?... metal disc
Could this be diyed someone
wanna start a business with me?

Less data, but tiny, so you can have a couple of hundred of them in...

Archival CD Uses Gold Layer
These arcivall disks use gold and are said to last for 300 years... [Grogster, Jul 23 2010]
there might be room on these? Or room for more. [bungston, Jul 23 2010]
How long would this last?

||Try Joseph Marie Jacquard as a starting point - you
could probably improve his process using thin
slivers of metal and precision laser
etching/punching - but you're going to find it
difficult to store any more than minimal amounts
of data - Let's say you want to store a rather
meagre (at least these days) 1GB of data, and you
can somehow figure out a way to physically store
data at a density of 1kb per mm² (still rather a
lot - that's a precision of about 800 dpi if my
maths is right), you're going to need sheets of
metal 1m² in
size to store 1GB. I have data backups that occupy
+350GB at home. By the time you get to store
4046GB, you will have approximately an acre of
metal in your lockup.
||Let's also talk about speed - how long would it
take to etch/print 1kb of data into metal?
||One should be able to encode a metal plate with data as irregularities read by a laser just as a CD or DVD. Maybe this idea is for metal CDs. Or ceramic: more durable.
||How long are you storing the data? 10 years, a
hundred or a thousand?
Most CDs stink and only last a couple of years,
though I think there are some that do. Tapes are
good for a decade or two, I just heard about
something that would last a hundred, though it
escapes me now, maybe SSDs. The big problem
past a hundred years is using a format that is
readable then. The classic is the gold record sent
with Voyager. I'm sure a souped up CD burner
could burn trillions of holes in a SS disk, but who
cares if don't have a CD player in 1000 years.
||I'm pretty sure there are existing ventures to encode data as
surface bumps, at higher density than CDs or hard drives.
Will go look.
||climb deep into a cave and paint it on the wall. what purpose does long term stable data serve?
||It's not **exactly** a metal disk, but see [link] for an Archive Quality CD that uses a layer of gold that is purported to last for 300 years... so I wouldn't **exactly** call it baked, but it is certainly half baked. Now at last your BeeGee's albums are safe! I have purchased these before, and they are the coolest looking CDs I ever saw.
||"One ring to rule them all, one ring to find them ..."
||Oddly, the HB doesn't seem to support the Old Mordor font ...
||I think the generally accepted method for ultra-long-term
storage is junk DNA.
||Also, [vtolled] doesn't say how many bits per square mm, so
stated, this is very baked: engraving "Revere fecit" on a
pewter tankard isn't exactly high tech.

||The first things our distant descendants will do, of course, is
eat the silica and die lingering deaths.
||We question the point of your species developing any data storage technology longer than an individual human lifetime.
||After all, it only needs to last until after you're dead. Then you can't be sued or called to answer for your sins/crimes/errors/doubtful expenses claims.
||Posterity can look after itself.
||I have a silica gel pack at home somewhere with the words "Through Away" written on it - all the other ones I threw away, but this one, I think I'm going to keep.
