Like the lens, if the disc is dirty or has scratches on it that impede the tracks of data then the drive will also not be able to read it, and will eject it. To remedy this, you can try blowing compressed air into the drive in an attempt to dislodge any debris on the lens. If this happens then most discs inserted into the drive will be ejected, including commercial discs. Over time a drive's lens may collect dust and debris, which can prevent the lens from reading properly. If your drive is ejecting discs, it can mean one of four possibilities: To see this, on a working drive just insert a disc label-side down, and the drive will eject it. Usually the drive will recognize a disc and attempt to communicate its file-system structure to the computer, but if it cannot read the disk because of scratches or dirt, then it will spit the disc back out again. This happens because the drive cannot recognize the formatting of the disc and also does not recognize it as a burnable medium. While optical drives should accept formatted and blank optical media, there are times when people find that discs automatically eject from the drive when inserted. Apple included an optical drive in most Mac models, and even for those who do not have an internal drive there are options for using external USB or Firewire drives.
