I ordered a spindle of Veratim Lightscribe (Version 1.2) 52X CD-R Media 30 Pack in Cake Box Spindle from Supermediastore and just found out why they won't play. Ther aren't Verbatim afterall!

I've had nothing but coasters from these disks and didn't know why. I then ran a media info check and seen that they were CMC Magnetic media which I'd never even heard of!

Does anyone know what these are and why Supermediastore would package them with a Verbatim label?

Thanks!

CMC Magnetics manufactures the CD-Rs and DVD+/-R discs for Verbatim and many others. Verbatim also buys from some other suppliers, but CMC is the largest in the world.

Have you used 52X CD-Rs before? At what speed? CMC uses phthalocyanine dye for the faster writing speeds, and some older drive may not work as well with discs rated at this speed. Slowing down the recording speed is one solution.

What do you mean by "coasters"? Do they fail to play in the drive that recorded them? Or do they just fail in a different player?

Ok thanks a lot, that is good to know that they are actually Verbatim media!

And I was wrong to call them coasters because they do in fact play on my PC just not in my car stereo. That is odd because the HP Lightscribe cd-r played in pc & car both.

Do you think it's just my car cd player being incompatible or is there something I'm doing wrong here? My cd player is an Alpine that's about 6 years old.

Thanks again!

It is better to have them not play in your car stereo than in the computer drive because failure to play in a drive suggests problems with the quality of the recording. As for car players, many of them do not play certain discs well even though those discs meet all the specifications required of them. Sometimes the causes stump even the most experienced engineers.

The HP media are also manufactured by CMC, but they may be from a different stamper with different geometry. My only suggestion is to try to record the discs at a speed of 24X or 32X to see if any reduction in jitter can improve things. Don't record at speeds lower than that because the dye can then be recorded at too high a laser power. If that doesn't work and you don't have another drive to try, you may have to use those LightScribe discs on players other than the Alpine.
