Cd-rw

[hotrod351]

well i just burned a couple of cds from itunes and found that they won't play in my radio shack cd player but will play in my sony dvd/cd player. they are cd-rw disc and when i used toast 7 to burn them it said that most players won't play cd-rw disc. i have a few cd-r but when i try to erase them it says that theres no disc in the tray. what am i doing wrong.

Erm... I don't understand what your questions are.

1) You have a player that won't play the disc. Do you have any evidence it has ever played a CD-RW? Most parsimonious explanation would be that it cannot play CD-RWs.

2) Erasing the CD-RW.... how are you trying to do it? Try using Disk Utility.

Also what kind of hardware? You have a tray? Is this on a Mac Pro? Not very many Macs have tray-loading drives....

what i have is a power mac g4 digital audio. but im using a iomega external burner to burn disc. im able to erase a cd-rw and record my music from my itunes playlist but a warning comes up and says that most players can't play cd-rw disc.

Read my #1 again.

Also if you haven't already done so, investigate whether Patchburn (http://www.patchburn.de/faq.html) can be used to increase the compatibility of your drive with OS X.

Oh, I'm sorry, I understand you now.

CD-R is a disc that can be recorded only once. It plays in almost any CD player.

CD-RW is a disc that can be recorded many times and erased. It does not play in all CD players.

You should buy some CD-Rs. They are very easily available. Brand is usually not too critical anymore.

ok, now i understand. a cd-r i can record music to, but only once, and the cd-rw i can record over and over again. isn't, and im sure there is, a way to erase a cd-r so it can be recorded on again.

isn't, and im sure there is, a way to erase a cd-r so it can be recorded on again.

No, there is not.

CD-R = Compact Disc - Recordable
CD-RW = Compact Disc ReWritable

CD-Rs are a one shot deal. Once the session is closed, there's no more writing to it. There is no possible way to erase it.

No, as far as I know, there isn't. It's a physical limitation (the method used to "burn" the disc using the laser in the drive) and not a software limitation. They're very, very cheap. Not that I promote unnecessary waste, but they are so cheap that needing to re-record them isn't such a big deal for most people.

ok, thanks for the information.

That warning seems to be correct then.

Use CD-Rs. And CD-Rs cannot be erased. Once they are written, that's it.
