by antiquefart - 2/16/09 10:41 PM In reply to: Sanford Sharpie CD \ DVD Markers by Winchester257Thanks--I was curious about that too. But this just looks like a marketing gimmick. It's hard to imagine the ink type in these things is really any different from standard Sparpies. You're just paying a bunch more for four colors, and two different point widths. I'm ready to assume that regular Sharpies will be just as safe for writing on discs--but I'm willing to stand corrected if that's wrong.
CD / DVD Sharpies Are Different From Regular Sharpies
by Winchester257 - 2/17/09 7:03 AM In reply to: special markers by antiquefartThe following information is from the required Material Safety Data Sheets which can be viewed on the Sanford Sharpie web-site :
Regular Sharpie Composition = Dyes, n-propanol (71-23-8), n-butanol (71-36-3), diacetone alcohol (123-42-2) *
CD / DVD Sharpie Composition = Ethanol (64-17-5), 1-methoxy - 2-propanol (107-98-2), Dyes *
As you can see,among other differences,the regular Sharpies have diacetone alcohol and n-butanol which the CD/DVD Sharpies don't have.Instead,the CD/DVD Sharpies have ethanol. There's not a real big price difference,either.
I stand corrected

I've always used Sharpie's
by TheAdman - 3/7/09 7:57 PM In reply to: special markers by antiquefartThough admittedly purely anecdotal, I've used Sharpie and even "Industrial" Sharpie markers for years on writable CD's and DVD's. I've never encountered an obvious problem with a Sharpie damaging a disk. I do have a few 10+ year old CD's that don't seem to want to read anymore, but they are pretty scratched. I have others of the same age that continue to work just fine... all with Sharpie ink on them.

Data loss of CD & DVDs
by R1000 - 2/13/09 7:30 PM In reply to: CD/DVD Shelf Life by ZouchFantastic info! I just have a couple things that I ran into that may or may not be of interest.
Yes, I agree, DO NOT USE PAPER LABELS UNDER ANY CIRCUMSTANCES! I have lost quite a few when I was using the paper labels. Appears that the glue eroded the thin film on top of the cd and made them unreadable.
Now I use the inkjet printable,(other printable methods are probably just as good) cd s and dvd s for all purposes!
Another item of interest is storage. I use the "STAKKA" units. They hold 100 disks. Totally dark inside. Haven't lost any printable ones in past few years.
Here is a tip that may help to recover some of the disk that hereto fore was unreadable.
USE A BLUERAY READER! They are quite a bit more sensitive to data and will sometimes recover data that otherwise would be lost.
I discovered this by accident. I have some cd s of my late Brother in law s band which was recorded off a vhs tape. My normal CD/DVD player did a lot of dropouts. By accident, I put this one in my new blueray player, IT PLAYED COMPLETELY THROUGH! Maybe it will work for you, don't cause any damage to try! If you have any success, please post back with the results as I am very interested if this was just a one time coincidence!
Best of luck to all.

Do Cd's have a shelf life
by gene_71 - 2/13/09 11:37 PM In reply to: CD/DVD Shelf Life by ZouchYes they do have a shelf life. The ones I h ave used so far don't very long at all. But color was mentioned as a factor. I am not really all that knowledgable about this , But I bought some CD-R's a while back that came out around christmas and were all colors. I had nothing but trouble with those, especially the green ones.They were put out By Sony and were on special. I won't buy anymore of those. I have had the best luck with the plain white labels, But they don't make those anymore. They are all silver color now. But Pretty much reliable. Never have trouble from writing on them either. main thing is to keep them put up and away from the elements.

In regards to the color issue. I don't think that the original answer was referring to the color of the disc (top surface). He was referring to the writable surface. They usually only come in a couple of different colors, i.e. gold, silver, and purple. I have not seen a green writable surface but I guess anything is possible. I would definitely stay away from any other than gold and purple as that is what I too have had best luck with.
Do Cd's have a shelf life
by spaarks - 2/17/09 8:11 AM In reply to: Do Cd's have a shelf life by gene_71There is a freeware application called Dvdisaster, which adds an error correction code to CDs and DVDs. It is claimed to extend the life of the media. You can use it to monitor the state of your media from time to time. It will show you if your media is beginning to deteriorate.
good idea if made part of an I/O option that is standard
by Culebra - 2/17/09 8:48 AM In reply to: Do Cd's have a shelf life by spaarkshowever, a proprietary I/O encoding scheme will require the proprietary OS driver to read back. Drivers incorporated into an OS are a lot more challenging to keep current since they are at a level below the application interface to the OS, which is by definition intended to be more consistent over time (as much as possible).
Which CD brands are best
by OldRattler - 2/15/09 9:47 AM In reply to: CD/DVD Shelf Life by ZouchAnyone have a recommendation for a name brand CD that is especially reliable? Purple, gold, or silver don't mean much to me, but if someone has a specific brand recommendation, e.g. Sony Model xyz it would help. Their cost has dropped enough to not mind spending a little more on better quality. Thanks much.
cd brands
by JOHN A. JOHNSON - 2/15/09 1:00 PM In reply to: Which CD brands are best by OldRattlerThe only brands that I reccomend are Fuli and TDK. Imation, HP and Sony, I would not use if they were giving them away.
suggested media
by tomsw - 2/15/09 4:04 PM In reply to: Which CD brands are best by OldRattlerOld Rattler requested suggested media.
I strongly suggest TDK, Phillips, and Verbatim.
I am told Taiyo Yuden and Ricoh are equivalent, but don't see them or know who might use them.
Brand Names ( Found In Retail Stores ) Do Not Matter
by Winchester257 - 2/16/09 7:23 PM In reply to: Which CD brands are best by OldRattlerAll of these brand name blank discs are made in the same factories,mainly in Taiwan but sometimes in China,India, or Japan.
For example,you could buy a 50 pack of Maxell CD-R's one day and then three months later buy what looks to be another of the same Maxell 50 packs of CD-R's but,you could end up with two different batches of discs from two different factories in two different countries with two different levels of quality.The brand name of blank discs which are commonly found in retail stores means little to nothing.
For cheap (name brand or otherwise) store bought blank discs,I would strongly recommend the ones made in Japan versus the ones made in Taiwan,China,or India.
The real quality discs for longevity are the "Archival Grade" Gold discs.This is important because,there is actual gold used in these discs.The reason for that is because gold resists the oxidation caused by the earth's atmosphere.This prevents the early degradation of the discs.
For the most part,these archival grade discs have to be ordered from places such as EncoreDataProducts.com or MediaSupply.com .They are made by MAM-A (Mitsui),Falcon,Verbatim,Quantegy,Kodak,Apogee,HHB,and by Delkin Devices (E-Film).I can personally speak for the first and last names that I mentioned plus the Kodak Preservation Discs but,they all should (more than) do the trick because of the benefits of the gold layer.
(NT) Exact information I was looking for, thanks.
