Question: Can you use a sharpie on these? Anyone know?
Document: We have used hundreds of Taiyo Yuden disks of varying types (CD and DVD)and I don't think that we have ever had a single bad one. I'm careful about markers, so I don't know if they are "Sharpie Resistant". Highly recommended.
Super basic, nothing fancy about these, but they are well known to be the best quality optical media, and my experience with them hasn't diverged from that. Taiyo Yuden is the only name to know in blank CD-Rs.
Did you know that on CDs and DVDs, that the recording layer is actually closer to the top of the disk than the bottom? One time we tried breaking a Taiyo Yuden disc to see what it was made of.
These sellers don't include the most VITAL info -- the QUANTITY of what you are purchasing!! NOWHERE could I find the number of CD's listed! Who cares about the dimensions of the package, when you don't even know HOW MANY CD's you are purchasing in the package?!? Ignorance,I tell you!
I can say is that this product is top notch stuff. I would suggest this product 2 anyone who burns cd's or dvd's it's just that great.
These are my favorite media and burn flawlessly almost everytime. Plus, after they get banged around in my car glove box, they still play perfectly unlike many cheaper discs where a few scratches render them MIA.My biggest beef and reason for only 3 stars is the packaging. Yes it is not the product per se, but buyers need to know this is a huge problem with Amazon.
I have used over 1,000 of these Taiyo Yuden cd-r's and can't remember ever finding a dud! They are perfect and are claimed to be 100 year archival quality. Don't forget to buy the special cd/dvd pens to write on them. I found the 4-packs of Sharpie double-ended pens to work the best on these super-shiny surfaces.
If you need to burn important files or music to a CD these are the only ones to use.You are taking a risk with any other brand, these are the best made.
High manufacturing quality. I save them for my most important projects and use cheaper ones as my throwaways in my recording studio. Worth a few extra bucks if you want error free CDs.
I use these for &#34;work tape&#34; recordings on CD's that I label with a Casio thermal disc printer. They work beautifully and have never had a problem with them. I am not a technical recording expert but my reading has found these to be highly recommended by those who are.
Answer: A year ago, I researched the question of whether you can use a Sharpie marker on the back of CD-Rs, and I came up with two completely contradictory answers. The more frequent answer was 'No! You must never use a Sharpie on the back of a CD-R. Sharpies contain solvents, and those solvents may damage the very thin layer of plastic that lies between your markings and the data-layer of the CD-R. They make water-based markers specifically for writing on the backs of CD-Rs.'The less frequent answer (but this came from the headquarters of Memorex or somebody else quite authoritative) was 'Sure, we do it all the time! Never had a problem with it.'I can't tell you whom to believe. Sharpie does make an Ultra Fine Point marker, and you can safely write with that in the central region of the CD, where there is no silver and no data, but that solution may not be satisfactory to you. And there are the water-based markers, specifically for writing on CD-Rs, but I have not tried them. I wonder, how permanent could a water-based marker be?So, I was unable to find a definitive answer to your question. It's like the world at large: everybody's got an opinion, but nobody's got an answer.Good luck!
