Blu-ray recordable has longer life expectancy than DVD recordable:
<http://www.blu-raydimensions.com/recordable-blu-ray/recordable-blu-ray-discs/>

There is nothing there that indicates anything about absolute longevity,
just likely relative longetivity of the various types of recordable disks.
But guess what decades old music is archived on...;-)

Optical disc. Check with the Library of Congress.

and at a
current price of $12 each for Blu-ray blanks, that would
hardly be cheap.

About half that price in a cake box:
<http://www.supermediastore.com/memorex-32020013358-blu-ray-write-once-4x-25gb-bd-r-single-layer-media.html>

If one wants them by the ton...;-)

15 in a cake box for less than $100, typical of many optical disc
purchases, is hardly a "ton". ;)

Tape is still cheaper, good long
term, and it doesn't rely on an often-fleeting die image for recording.

True, false and false. Tape is known to be a poor archival medium due
to problems of print-through*, binder breakdown, shedding, physical
damage, etc.

* <http://en.wikipedia.org/wiki/Print-through>

Tape is not a good archival media.

Rediculous.

True nonetheless. Do some research.

Heck, even my decades old
analogue VHS tapes are just fine.

That's anecdotal, you are very lucky, and I'm willing to bet there has
been significant signal degradation.

Commercially pressed CDs,
DVDs, and Blu-ray disks *are* relatively permanent, but I have
seen writable optical disks become useless within a couple of
weeks.

Then they were probably cheap junk in the first place or improperly
written.

When people buy the cheapest junk they can find and then complain about
problems I just shake my head. If you want your optical media to last,
then you need to buy a top brand like Taiyo Yuden or Verbatim
DataLifePlus that actually makes their own media. Most brands are the
cheapest discs they can find at the moment on the OEM market.

Trust them if you want for archiving (or for use in showing
material to others), but I will continue to use a combination of
multiple hard drives and tapes for archiving (although nothing is
permanent, of course...).

OK. "Different strokes for different folks."

I've already long since retired all of my LPs and tapes, digitizing and
transferring to optical disc (high-grade CD-R and MO). Further
degradation is no longer a concern.


Please note that, unlike recordable CD and Blu-ray, I give only a
qualified recommendation to the various recordable DVD formats, because
they are based on a laminated technology that might lead to problems, as
compared to the single polycarbonate layer in the other formats.

Please also note that I speak from experience, having been in management
of a company that made tapes and discs.
