I want a stuck up middle finger smiley so I can insult Mr K better, but it's not gonna happen.
I believe smiley central has many smilies like that. You could maybe install it and let us know. I think you also get all sorts of cool toolbars and pop ups with it too. I just love that.
I was going to say something about my inbox but that would be tempting the fates too much.
On the other hand, if we 'draw' smilies can we have them added to WOS?

Loads stuff to make adaware/spybot go nutty huh?

You'd be exciting Mel too, I'd wait til he's had his medication if you're gonna do stuff like that :D

Tcha, good idea but Martijn would never go for that. Well, maybe if we offered something he couldn't refuse.....
I'm just gonna do the ":bird :middlefinger :upyours thing. :lol:
Hey, I was a member, now i'm a user, soon I'll be a pusher, when do I become manic?
Back on topic....
I laid in my supply of TDKSA90's a while ago. Also a fair few minidiscs.
Someone said that MD compressed data. I don't think it does, I'm sure it stores data as a sample. But you can select the sample rate i.e. default is 44.1 stereo I know my sony takes a direct optical digital feed from the CD player. Both the hifi and the portable (MD's). But you can drop the sample rate to a qurter that and go mono but it's not the same as compression.
The MD has been most convenient for recording live broadcasts in CD quality from FM radio and Freeview.
One day I will get a freeview card for the PC but it has to take the RGB from +128 in real time. OK it will need a custom cable but realtime is most important delay would make playing games impossible.
The tapes are good in the car - mine only has a tape player, but mostly I have an MP3 player plugged in through one of those cassette with a wire thingies. Sound quality not being high priority in a car. What with the terrible acoustics and engine and road noise. You can compress the shit out of music and you can't tell the difference.

So the same can be said of CDR and DVDR then? Neither are recorded magnetically. However, a tape does have a magnetic impression placed upon it, and it WILL fade in time, the length of which would most likely depend upon the storage conditions. As has already been pointed out, CDs and DVDs are not happy in the sun, floppy disks oxidise.
What then, is the most reliable medium for data storage (excluding papyrus, which is known to last at least 2,000 years :D )
One of those lab experiments where you "age" something artificially was done on minidisc, and they were found to work perfectly for over 100 years, which is far better than the 7 years given for DVD-R!
Minidisc rules! :D
Oxidising is one problem.....but you also have the loss of magnetic capability that floppies gain over time. I had a couple of unopened packs with DSDD-floppies for my Amiga, and when I finally started to use them, I had to trash several of them, just because of this.
I had a similar problem with some Amiga floppies, a few of my games were lost because the metal slider went rusty! (the disks were quite old so it could have been age) I don't know how that hapenned because they weren't stored anywhere cold or damp, just in a cupboard.

I heard somewhere that some of the first cd's that came out (in 1983) several have started to rot. Don't know if that's true.
I wonder how long a cassette can last? I have some cassettes that date back to 1990/91 that play perfectly (TDK are the best. Never looked at another brand). My dad has some Status Quo music (don't laugh!) from the mid 1970's that also plays no problem. Is it all down to the brand of tape?
I always burn CDR's at quad speed as whenever I've used a higher rate the discs wouldn't be readable after a year or so. With quad I've never had problems.

Being a seasoned ROIO (Recordings Of Indeterminate Origin) collector (the term bootleg is sooo last year!!!) I always burn my CD's as slowly as possible.The slower the speed the deeper the recorder burns into the CD and thus the longer it will last. You only learn through experience, I have a few CD's which will not play anymore luckily I archive everything and was able to burn new copies. Buying a top quality blank CD is also essential, you really do get what you pay for I use Taiyo Yuden which are considered to be the best.
I reckon best thing to do is backup to CD and copy that CD every year or so. Of course, we could have a hex dump printed on paper and type it all back in again, but even a floppy disk holds a month's work at my normal typing speed :D

CD-R's use a dye that reacts to the laser. You aren't actually burning into the CD.
What usually determines how long CD-R's will last is how stable the dye is.
The slower disks actually used a more stable dye that was slow to react.

You are quite correct, As far as I remember the term burn was used because the dye is darkened (or burnt). Choice of dye used is extremely important, Taiyo Yuden use the Cyanine dye which at one time was considered quite unstable but now with additives has improved dramatically.

The oldest CD I have is Queen - A Kind of Magic from 1986. This has been mistreated, scratched etc in the 20 years I have had it. The "silver bit" has clearly degraded, as this is only in the places where the Printing is. I can't be sure is this is from being left in the light etc. But the disc is now unplayable.
Do you think I should send it back to EMI for a replacement ??

Leaving CD's in the light is a major reason why they stop working. UV rays cause irrevocable damage. Especially when people leave them playable side up to avoid them being scratched...
remember folks you are more likely to make your disk irrevocably unplayable by scratching the printed side as it is much closer to the pressed information layer.
Whereas the clear plastic side can be cleaned with isopropyl alcohol to remove dirty there is also repair creams available that fill in and polish out scratches but I've never needed to source it yet.
Mind you I still find a quick rub on the trouser leg works wonders.
Just been playing my JM Jarre the Essential Collection CD..... It does have a flaw that makes it skip halfway though track nine.
But the rest plays ok.... not bad for a 24 year old CD. The print has not worn through on this disk either.
I was given this disk by my sisters BF (now husband) way back in the 80's. His uncle had a HiFi shop and was given the CD when they first came out to demo the Sony CDP101 to potential customers.
Well the CD, case and covering letter are now in the hands of our faithful postal service, heading towards EMI's Customer service department, by "signed for delivery"

MD does use a compression called ATRAC and it's lossy. It's just different and less noticeable than MP3.
http://www.minidisc.org/charman/atrac.html
Once again I stand corrected. It looks like the 80 minute MD's hold about 160MB of data.
Looks like it is about double the standard MP3 finger in the air meg a minute.
It's all propaganda but I do like his analogy:
<cite>These are the type of people who claim they could still here the mouse fart during the explosion.</cite>
I can't tell the difference in sound between a CD and a minidisc copied from a CD.
But I can tell the difference in sound between a CD and an MP3 or CD recreated from MP3.
But then my ears are getting older and I'm sure that will become harder for me to spot.

Yep that's right! If you look after vinyl it can last forever!

My oldest CD is from 1985, and it's still in perfect condition.
CD's were said to last for only 20 years, but I haven't seen any "rotten" CD's yet.
And if you wanted, you could make them out of papyrus!

Go on, I dare you :D
Accepted.
Will post progress.
Found the disc and heres some photo's for posterity.
