LPs are harder to track though; if only we still used wax cylinders then
things would be even better.

Every time you play an LP, you are wearing it out. Eventually, it becomes
unplayable. Not so with a CD.

You can make exact duplicates of CDs, not so much with LPs.

Sindi in resp:6 :: are you talking about CDs from the Ann Arbor
District Library? I've had a few scratched-up rock CDs from
there, but (nearly?) all of the numerous classical CDs I have
checked out over the last two years have been in fine shape.
Yes, CDs can get scratched up if you don't carry them in their
cases -- I recall one co-worker who would toss unprotected CDs
in his backpack, yeowch. But my impression is that the people
who check out the library's classical CDs handle them well.

Classical CDs from the main library. Usually one or more tracks are
unplayable. DVDs also have bad areas, videotapes did not. CD-Rs have a
finite lifetime because the dye fades. Tapes even last longer. I have
records from the 50s that still sound the same as new (which was not so good,
but they have improved since then).

Sindi? Dye? in CD-R's?
People who do not take care of their medium, no matter what that medium may
be, it is not going to wear well over time. Be it paper, tape, vinyl, or CD.

Yes, dye. In CD-Rs.

Okay. But I am all digital now, she says. I rip my CDs to mp3s and carry
'em all on my little iPod. It is very nice. But I have to say that I
have CDs that are old and do not have any degradation problems, given that
I always take good care that they are in their cases when they're not
being played. My older cassette tapes and videotapes have started to
degrade to the point that I can't use many of them. (And don't even
get me started on eight-tracks.)

What's the best way to preserve DVD-R's of my family home movies?

Do you cassette tapes degrade (oxidize over time) or simply wear out?

I think videocassettes tend to get brittle and stretch.

Make as many copies as you can and distribute them to family members.
Keep making copies. Copying DVDs is lossless so there is no need to
preserve some "master copy". Distribute the copies so that if a disc
ever goes bad, you have plenty of places to borrow a disc from to make
more copies.

There's no way to make a master copy which can be preserved? What if I have
a stack of DVD-R's I want to keep in a safe for decades? Do I have to keep
going back to make newer copies?

I don't know Todd. I just think making copies and distributing them is a
pretty good way of making sure they are always available.

What about storing the contents of the DVD-R's on an external hard
drive. That wouldnt have the same sorts of dye problems

After just a few years you'll take the whole stack and copy it onto a
handful of HD-DVD (or Blu-Ray or whatever) discs. Then after a few more
years you'll copy that onto a megacapacity disc that can store all the
knowledge in the history of the universe and that can fit up your ass.

And then, when you need facts to win an argument, you can just pull them
out of..
Actually, it'll be a lot like things are now..

Here's where I'm going with this: You send a CD to the Library of Congress
as part of your copyright process. Assuming it is music or movie, how do you
know if it will still be preserved in 30 or 40 years? Call me a scrooge, but
I may not want to give copies to other family members. At least, not at this
time.

Scrooges can pay for climate controlled safes for preservation. :-)

Digression back to music retail:
The Wall Street Journal covers the stranglehold of Wal-Mart, Best Buy
and Target on what is left of CD retailing -- and the news that those
chains are looking to shrink their commitment to slow-selling CDs.
The chains are also difficult to impossible for specialty music
labels to deal with.
The big-box stores now control 65% of music sales, up from 20%
a decade earlier.

Jvx60dlqeg_20080426.html?mod=rss_free
The WSJ article will likely only stay available for a short time.
Here is a bloggy summary which should have more persistence:
"Big Box Retailers Not Doing As Crappily As The Rest of the
Industry -- But They're Getting There"

And, a recent item which I have now lost reported that many Wal-Mart
stores are going to remove about 20 feet of CD bin space to make room
for iPod accessories.

Good lord! (I don't know that they need to sell that many accessories -- a
good case, some earphones, and maybe some speakers, if you really want 'em,
and you are good to go!)

I guess I am a little less knowledgeable than I thought. I never really looked
into what the difference was between a CD and a CD-R and why it is able to
write on a DVD-R.
So a CD or DVD is a longer storage medium because the reflective bumps are
imprinted in a reflective layer rather than a dye.

Actually, the manufactured CDs are molded/cast with the bumps, then have
the reflective layer deposited on top of that, which is then sealed
with laquer. I'm assuming DVDs follow a similar process, but haven't
confirmed it.
The burnable discs are done with a change in a chemical layer.
