Sometimes you can make a disk readable by slowing down the write speed. (Of course you can't re-use the CD and you have to write all the information at once, but re-use is usually less of consideration in a disk you're passing on to someone.) CD-R disks have more contrast than CD-RWs and only cost about half as much. If you burned the CD on a rewritable disk, try putting the information on a read-only (CD-R) disk. The fixes involve doing things differently when you burn CDs. CDs made on a computer don't have as much contrast as commercially made CDs, and some CD players, especially older ones, have trouble with them.įortunately, it's usually possible to work around the problem. Unlike commercial CDs, where bits are pits are pressed into the disk to represent information, CD burners in home computers rely on using a laser to produce different colored spots to represent the same information. Have you ever burned a CD for a friend, but it won't play on their computer? It plays fine on your system, but the other computer acts like there's nothing on the CD.ĬD drives differ considerably in their ability to read homemade CDs.

Contrast can sometimes be increased by burning at a slower speed however, sometimes the only solution is to replace the drive with a more modern one. The drive reads factory disks but not CD/DVD-Rsġ) Factory CDs have more contrast between the ones and zeros than CD-Rs.
