In other words if your drive is reading and writing with no errors on the disc (do a scan disc) then you will not improve performance by cleaning the lense - how can you improve on perfection? It will not speed up your drive etc. G P |

| 95520 | 2002-11-04 03:09:00 | The usual cause of "it's stopped working" is that a particular CD can't be read. There's so much redundancy recorded on the CDs that a lot of errors are "recognised and corrected". It's only when the contrast of the reflected signal gets below a critical point that you can not read. A film on the lens, or on the CD, or major scratches or a "hole above a certain size" (I believe that a CD should be still readable with a 1/4" diameter hole punched in it :D) is what causes this. If the laser power is reduced by old age, this can get below the sensistivity of the detectors. |

| 95521 | 2002-11-05 02:36:00 | would u say using the liquid from a bottle of TDK VCR video cassette liquid to clean the lens of the DVD/CD is ok?? Saves me costs of buying if it can be used. Rayonline |

| 95522 | 2002-11-05 04:08:00 | I tend to assume that the bottles with "headcleaners" whether cassette, video, floppy disk ... are isopropyl alcohol, and therefore OK to use. If you are in any doubt, try a drop or two on a piece of clear perspex. If it dissolves it or makes it cloudy, it's not safe to use. :D | Graham L (2) | ||
| 95523 | 2002-11-05 07:06:00 | I would like to thanks one and all for replying to my query. I now feel well versed in the art of CD lens cleaning and am amazed at the responsiveness of everyone above. Thanks again Richard |
