message referring to no disc being in the system. This can be infuriating because you can see that there is cd error ford a disc, however, the CD / DVD player cannot. Every time the tray closes, the cd error in car laser beam fires two long bursts of laser light, and the focusing platform moves up and down attempting to focus the cd error in cd player beam. This is the time when it is looking for a disc. If the laser has failed, then it will not be able to detect a CD and therefore the error message appears. I normally do miis cd error two things when this happens. I normally clean the lens just in case there is dust on it obstructing the laser path. If cleaning the lens does not solve the problem then I make sure the laser is working. Obviously one should never look directly into the laser unit, you would have to be plain stupid if you did that. The laser light is bright enough that one can see the

diffused red light from a distance obliquely. A piece of paper the size of a standard CD within the tray can also help, because when the tray closes, one can see the diffused red light on the paper. It is usually bright enough and visible from the other side of the paper. If there is no red light, then the laser has failed. Back in the 1990s, I used to fix many of these and it was always either the spindle motor or the laser that failed. These two components are in constant use and wear out the most. Laser diodes do not last forever, especially on the early players manufactured in the 1980s. It would be very surprising to find a player still working from that era. Most of those units used cheap motors where the brushes wore out within a few years. Moreover, if that did not fail, then the laser surely would. The laser diode manufacturing process was not as refined either, and those diodes had a short finite life to them. Most of those early CD players would be hard to find as they often ended up in landfill. I have come across many high-end players of recent time that use the same cheap mass produced drive mechanisms. More

Scratched CD Every user has had trouble with a scratched CD. In the case shaker 500 cd error of data CDs (CD-ROMs), the drive cannot properly read the CD, thus giving rise to reading errors. In the case of cd error correction audio CDs, the CD skips when we play it. The first thing to do when coming across a CD with a read error is to clean it in order to check if the error is http://www.petervis.com/CD_and_DVD_Players/no-disc-in-cd-player-error/no-disc-in-cd-player-error.html being caused by a dirty surface. You can even wash the CD gently with a little detergent, using your fingers to clean it. (Avoid sponges, since they can scratch the CD.) If the error persists, try reading or playing the CD on another drive. If another drive (or CD player, in the case of audio CDs) gives the same result (read error) (or skipping, in the case of audio CDs), http://www.hardwaresecrets.com/recovering-scratched-cds/ it will mean that the CD is scratched. Looking at it against the light, the recording surface (the flip side of the label) of a CD with this kind of trouble will allow you to easily see one or more existing scratches. A CD's data is recorded on a metal layer inside of it. This is a silvered layer on commercial CDs and is oftenly golden on CD-Rs. The metal layer is inset in a transparent plastic covering (polycarbonate) used to protect the CD's metal layer and to allow printing a label on the side not being used for reading. A CD-ROM drive or CD player utilizes a laser beam, which crosses the plastic layer and reads the metal layer. If the plastic layer is scratched, the beam will be unable to pass through it, resulting in a read error or skipping the music. In other words, if the data to be read are still in the CD, the trouble lies in the layer of plastic. As the CD's contents are preserved, a scratched CD can be recovered by polishing its plastic surface. After carrying out the above cleansing, if the CD persists in giving reading errors, just polish the scratched CD with toothpaste. That's right, toothpaste.
