CD-R’s. Can we make them more CD player friendly?
I use a Newmark duel CD player when I’m DJing. And I’ve sometimes found that some CD-R’s give it problems. Generally it’s when I put the CD in, and skipping through to the last few tracks on the CD. It has no problem with the first few tracks.
The thing is, this can happen randomly and can work on a CD one week and not the next week.
I’m using standard 80 minute 700MB CD-R’s.
Does any one have any recommendations on how to sort this out?

There are old cd-players which can't handle cd-r's.
Also when cd-players have been through some rough handling they can start to have problems with cd-r's.

I have similar thoughts. Try slowing down the burn rate.

You'll see a whole bunch of topics on this issue. Enjoy.

We've discussed the speed of your burns in this thread.
Basically, burn speed should be irrelevant given 1) a clean, scratch-free source disk, 2) clean lenses, 3) a clean, scratch-free CD-R, 4) a fast enough processor, and 5) no other hardware bottlenecks that slow down the read-to-burn reliability. Any of those factors could cause buffer underrun at higher speeds, which results in the burner saying "fuck it" and burning gaps of data onto the CD-R. Some CD players will freak out when reading through those gaps, others will tolerate it better. Nonetheless, slowing the speed down is only relevant to give the processor/burner more time to "catch-up" to read errors and not miss some information in the burn. If you have no such bottlenecks causing buffer underrun, then a 48x disk should be just as readable as a 1x disk in any CD player.
However, different CD players DO read CD-Rs differently. You should get one that specifically is labeled for CD-Rs and -RWs in order to guarantee that it plays CD-Rs more reliably. CD-R burn images are not as sharp and easy to read as commercial, "pressed" CDs, so many CD players that are not designed to accomodate for the differences might freak out. The cheap Numark CD players (especially the budget-dual CD player that comes in its own suitcase) are notorious for reading CD-Rs poorly. I suspect they are of the sort that freak out at even the slightest gap in information on the burned CD.
Also, the color of the CD-R affects its readability in non-CD-R players. Blue or green CD-Rs will be more likely to freak them out than gold or silver discs.

Just wanted to point out an article I saw today about making CDRs last longer
