The most scratch resistant cd-r's?

[acertim]

Is there any difference between a cd-r's scratch resistance when it comes to different makers or are they all made in pretty much in the same way and then branded with different logos? I am looking for the best and most long lasting cd-r's.

:unsure: I'm not sure any CD is all that scratch resistant, however TDK and Verbatims are pretty much the 'best'. ;)

Well actual pressed cd's are quite scratch resistant, however cd-r's go pretty quickly that I've seen.

I have heard that if you keep your cd in a decent case when not in use, it keeps them pretty scratch free.

Quite a few tips.

Scratching the bottom is the least of your worries, as the top is the thin layer which contains the data, and is vulnerable to the scratching.

Don't write on top of the CD, no matter what product you use etc. Precautions. Write on a label, stick it to a DVD case, and put it in the DVD case.

Ummm.... The data is on the bottom of the disc, not the top. It is perfectly fine to write on the top with a sharpie, or anything that will not scratch through the top of the surface.

Basically the top of the cd has to be solid as to not let any light through the disc. The laser needs a solid surface to read from.

Gah!!! Go scratch the top of one of your cds and then come back and tell me it still works. I want pictures too. Do it to a valuable CD please, so you'll remember and learn your lesson.

actually benplace, the shiny part you see on the bottom is a thin layer of film thats on top of the cd. without it, all you will have is a ring of plastic. go try it, get a razorblade and scrape the top off. you will see

A soft permanent marker is fine, and won't do any damage.

He said you could write on it with "anything that will not scratch through the top of the surface." He was 100% correct in what he said, I don't see why you're all bashing him.

The data on a CD is stored in the plastic, not in the top. The plastic has extremely small microscopic pits carved into it (in the case of pressed CDs) or has chemicals that react with the laser light to change their opacity (in the case of CD-Rs). The top is there to reflect the laser light back into the sensor, that's all.

I know you weren't talking about sticking the label to the DVD itself, but I just thought I'd mention it anyway, because I see people do it all the time. It's a very bad idea to put a label on the disc, because it can throw the balance off. The resulting unstability of the disc could even damage the drive.

that's one..

i dont know if that's the exact brand, but back on the screen savers (tech tv, tv show), they showed off some scratch resistant discs, they took screwdrivers and everything to scratch on them and surpringsly they still worked flawlessly afterwards.

so that's probably something you're looking at, i've seen those at futureshop, and they cost $5 CDN PER DISC!

So unless you're burning the FBI Database on there, I don't understand why someone would need something like that.

[brucebeh]

Ahh!!

I found it... it wasn't a scratch resistant CD, but a scratch resistant DVD!

this is the one where they took screw drivers and everything to scratch it and it still worked.

Wrong. Most if not all markers have some sort of chemical whether it's one, or another which can easily react with the afferming material.

If you're serious about backups, and keeping your CD's for their 'sussposed' 15 year life span, do as I said.
