    I have tried the water washing method. It does not work on the discs with moderate to heavy migration.

  • jonpardoll Sep 13, 2008

    I have tried the water washing method. It does not work on moderate to more serious discs with the problem. I have tried toothpaste. It also does not work.

  • jonpardoll Sep 13, 2008

    I understand solution #1; which is why I am looking for a real solution to this problem. There must be a way to burnish, or polish the plastic back to a clear surface...

  • jonpardoll Sep 13, 2008

    I will look forward to other expert advise. Thanks.

  • jonpardoll Sep 13, 2008

    As I said this is not a scratch problem, but a mottling of the surface of the plastic on the disc. I need to polish off the mottling which is now within the surface of the disc.

  • jonpardoll Sep 13, 2008

    I will wait for usable response here. So far nothing suggested has worked.

  • jonpardoll Sep 13, 2008

    Somehow, some way, there must be a way to repolish the plastic surface of the disc. Do not want to resort to disc recovery service.

  • jonpardoll Sep 13, 2008

    don't want to give up yet.

  • jonpardoll Sep 13, 2008

    Most surfaces can be polished. I need to find a way for this one. Am I the only one who has encountered this problem with plastic protection sleeves sticking to and mottling the disc they are supposed to protect?

  • jonpardoll Sep 13, 2008

    Hopefully, one of the experts here will be able to solve the problem...

  • jonpardoll Sep 13, 2008

    Again, has anyone else encountered this problem? What is a solution, not what I should not do...

I think you better don't insert such type of disks b'cos if you keep trying to read it may also damage the lens of your optical drive

  • Do not use strong cleaners, abrasives, solvents, or acids.
  • With a soft, lint-free cloth, wipe gently in only a radial direction (a straight line between the hub and the rim). Since the data is arranged circularly on the disc, the micro scratches you create when cleaning the disc (or the nasty gouge you make with the dirt you didn't see on your cleaning cloth) will cross more error correction blocks and be less likely to cause unrecoverable errors.
  • Don't use canned or compressed air, which can be very cold and may thermally stress the disc.
  • For stubborn dirt or gummy adhesive, use water, water with mild soap, or isopropyl alcohol. As a last resort, try peanut oil. Let it sit for about a minute before wiping it off.
  • There are commercial products that clean discs and provide some protection from dust, fingerprints, and scratches. CD cleaning products work as well as DVD cleaning products.
If you continue to have problems after cleaning the disc, you may need to attempt to repair one or more scratches. Sometimes even hairline scratches can cause errors if they just happen to cover an entire error correction (ECC) block. Examine the disc to find scratches, keeping in mind that the laser reads from the bottom. There are essentially two methods of repairing scratches: 1) fill or coat the scratch with an optical material; 2) polish down the scratch. There are many commercial products that do one or both of these, or you may wish to do it yourself with polishing compounds or toothpaste. The trick is to polish out the scratch without causing new ones. A mess of small polishing scratches may cause more damage than a big scratch. As with cleaning, polish only in the radial direction.
Libraries, rental shops, and other venues that need to clean a lot of discs may wish to invest in a commercial polishing machine that can restore a disc to pristine condition after an amazing amount of abuse. Keep in mind that the data layer on a DVD is only half as deep as on a CD, so a DVD can only be repolished about half as many times.

Im sorry that i am the one to inform you but damaged disc are really un-recoverable.
the lens that reads the disc can not jump to scratches and plastic that is why it is no longer readable.

tnx 4 using fixya,

Try cleaning CDs under tap water and dry them thoroughly with a soft cloth. May seem weird, but this often clean the CD better tan alcohol.

Ensure CD have no paper label on top before washing them.

    If plastic migration is at a really advanced stage, then the only thing you can try is using a recovery software like this http://www.jufsoft.com/badcopy/cdrecover...">CD Data Recovering Tool.

    Often damaged CD are not recoverable.

    Back up as many CDs as you can.

    Toothpaste is generally abrasive, even if this method is popular, it can cause more damage to CD.

    If damage is moderate and the reader can start reading the disk and get the file allocation table, then you can use a software like this:

    Naltech Software - CD Data Rescue,DVD Data Rescue,Multi Data
    If disks are heavily damaged, and the data inside is important, you can send them to a data recovery company, the fee for the service will be expensive:

    Here is one example:

    Acodisc CD data recovery

    There is no way to polish it, it is not a pair of shoes. If you use any abrasive product, the tiny invisible scratches on the CD surface will damage it.

Cd does not read


The lazer is shot, It will not read the info off of the disc any more, Verry costly to have it replaced,

When we put in a disc it comes up no disc and does not play (DVD and CD)


This is a laser pickup assembly problem caused by the laser becoming weaker overtime, or a pladder motor malfunction that the cd/dvd sits on, one possible solution is to clean the laser pickup lens with a Q-Tip and rubbing alcohol. If that fails! the assembly will need replacement "very expensive" or replace your machine "much cheaper"

I have a kenwood MIDI M-45 /MIDI M-757 audio system. The CD player won't play. The disc loads but error comes up NO DISC, can you help????


The cd unit is not reading the disc, the laser pickup may be dirty, or the pladder motor that cd sits on may be defective. If you can get at the laser pickup lens, clean it with rubbing alcohol with a Q-Tip very carefully in circular motion and allow several minutes to dry.

CD shuttle says no disc when there is a disc.


The most common cause of this is a dirty lens. If you can gain access to the optics, clean the lens using a cotton swab and alcohol. If that fails to resolve the problem, please post the make and model and further instructions will be provided.

Thanks,
Dan

When i insert a cd, the screen says E1?? an then ejects the cd again? its a car sterio (panasonic)


The player is unable to read the disc. Try removing the unit from the car and opening it up. Clean the lens using a cotton swab and alcohol. That may resolve the problem. If not, the optics will need to be replaced.

Hellllpppp!!! my cd player will not play ANY discs. the radio still works perfectly fine. i bought a cd head cleaner to try and fix the problem thinking it was just a dirty lense, but it says there are no...


open it up and get a q-tip with rubbing alcohol and gently run the lens of the cd player, those cleaning disks dont really work that great. you would be surprised how much dirt gets in there. but yea unplug it, take the screws out that hold the cover on, and you should be able to see the lazer lens and just gently rub it in one direction with a q-tip with alcohol. blow a little air after to make sure its dry and theres no lint from the q-tip. hope this helps, if not send me a message at btlee26@hotmail.com and tell me what model number and brand.

Cd player does not work


unplug it, unscrew the screws holding the cover on, you should be able to see the lazer lens where the disks go, now take a q-tip with rubbing alcohol on it and gently rub the lens in one direction to remove any dust. cd players are very picky about dust and even just a little can give you a no disc error. ive had to do it to many cd players, so this should work for you! good luck

Cd not plaing, shows no disk, but there are 5 disks inside


unplug, take screws out to remove the cover, take a q-tip dipped in rubbing alcohol and gently rub the lazer lens in one direction to clean it, you might have to turn the tray by hand to get it so you can see the lazer lens. its clear and is fairly small but youll know it when you see it it will be near the motor that spins the discs.
