Might eat into the disk... That's a point. I checked the ones I have already done - no sign of any trouble but I am keeping one of the duff disks on my desk and using it as a check to see if there is a problem. I suppose this is something that could happen with any solvent based pens. |

| 769431 | 2009-05-04 23:58:00 | Just an update on what I have found so far:- The "Papermate Liquid Paper" pen I tried was not a success. It is a correction pen but even so I was surprised at how little it lasted. After only putting a dual digit number (like 79) on six disks it started to run out of ink. As it cost $6 the thing just wasn't practical. I tried Stationary Warehouse but the only white pens they had were marked up as OUT OF STOCK. They were able to supply me with a Sharpie that writes in silver, and has to be stored with the tip down. On paper it is definitely silver but on my disks looks perfectly white unless you hold it at an angle to the light when it does show silver. So providing it lasts a reasonable time it looks as though my problem is solved. I will report back later. Tom |

Now you've really got me there - I've been using solvent based pens on CDs and DVDs for years and never noticed anything. What puzzles me is how this is supposed to work - the pens are used on the upper layer - the data is written underneath. So to my way of thinking the solvent would have to burn all the way through the disk to have any effect on data. I would be surprised if even sulphuric acid was capable of this. Where did this "myth?" start I wonder. Or is it a myth? |

Where did this "myth?" start I wonder. Or is it a myth? on CDs the data layer or at least the reflective layer is on the top of the disk so will be affected by sharp scratching to the top of the CD. the reading of the CD will be affected IF the pen is sharp enough to scratch the CD's top but depending on how much is scratched the error correction may have enough to recreate the data. writable DVD's have the data and reflective layer closer to the laser with a plastic layer on top and hence are more resistant to the pen tip and other things on the topside |

| 769435 | 2009-05-06 01:55:00 | I've used a vivid on my DVDS for years - no problems at all, dvds still run fine.... but have now moved to lightscribe, they come out quite cool |

| 769436 | 2009-05-06 03:05:00 | Are your VHS tapes commercially produced items? If so, how do you get over the protection barrier designed to stop the copying of them? I too have a Sony DVD/Tape machine that allows copying but I haven't even thought of copying the tape to DVD because of the anti-copying thingy. |

| 769437 | 2009-05-06 03:39:00 | the copy protection section on tapes is usually on the "non visible" lines of the video raster and can interfere with AGC and can screw up brightness and colour intensity as the video recorder tries to compensate, DVD recorders should be able to determine where the signal is and its level etc or it ignores the non visible section of the raster and shouldnt be affected, failing that, do what i've done and get a TV/video capture card a huge hard drive and a DVD burner and make a video server/VHS - DVD station | williamF (115) | ||

However I have always used felt tip pens and not ball tips. I must have thought about this when I first started and made sure that I only used these soft pens. It is a bit like opening a door before trying to walk through it. Something you do automatically without thinking once you have learned the correct methods. Again I do make the point that having used these pens for goodness knows how many years I have not had any problems with either CDs or DVDs rewritable or use once. |
