Frage von Kingsize:
Hello,
I have an important MiniDV cassette, which has run through water or the like thereof. Now I wo0llte questions, as I s.besten cleanse? Are there actually any extra cleaning or something?
Thank you
Antwort von steveb:
Water or similar na that is already decisive?

Hello!
Times I take this thread, because I have the same problem. A friend gave me his order to Editing DV camcorder with four mini-DV tapes brought back, and performed during transport to the worst case, namely, bathing them in a little beer. Two tapes are still more or less einwandrei two do now but wicked problems. One cartridge can always re-contaminate the heads, so that when it first horizontal stripes, and then comes to quite a blue picture. The only solution playing a few seconds with a cleaning cartridge. At the appropriate point in the other tape so it can indeed be better (because the dirt has probably rubbed off, but overall it happens again and again, very annoying when you can not go through the whole recording can be ran again and the cleaning cartridge.
The last mini-DV tape, it's even worse when running s.Anfang knotless few minutes, and then s.der always same place the Picture completely blue. In this case, but this is not s.verschmutzten read heads, for other cartridges are perfectly playable.
My question is: Is there anything else to save, you can leave the tapes somehow clean (), so that they run smoothly again? Externally it is not much to see, is not synonymous to the tape, but a few splashes of beer that have apparently been enough already. Please help me!

Is there anything else to save, you can leave the tapes somehow clean (), so that they run smoothly again? The cleaning of MiniDV tape I made the following experience: A customer sent me to a cassette that was cross stuck in his camcorder. Amid the tape was wrinkled, and was pulled partially stretched. Here and there was a tape of fingerprints littered synonymous.
In order not to unnecessarily pollute my recorder, I was not going to be easy to go through the critical part in the capturing, but wanted to fast forward the relevant section of tape by means of external Spulgerät.
Before that, however, I tried something else: If you only have to fast forward to a short distance, I have the tape less critical sections before and after the ribbon salad with a light detergent carefully freed of the fingerprints. So that I could still make a few inches of good, I wanted to capture as well.
Then the surprise: When the recorder reached those cleaned section were head drum and drive is completely braked. - I initially thought s.eine static electricity and unwound the tape in the external Spulgerät again to complete. However, synonymous with the second capture attempt stopped the tape recorder s.der purified body mercilessly.
Apparently been removed by cleaning synonymous lubricating coating on one tape. Thus I was able to capture only the part that I initially had before.

What a "light" cleaning products did not you, Mark?
For us to work isopropanol is the lightest cleaner, but I would be careful not to s.meine-DV tapes to go!
@ Puschel: uneasy idea to pull the tapes through the camcorder too dirty. GANZ offense. Please try it again niht, sowas like the drum head and not at all.
I would be with a little distilled (!) + Water may taste a little alcohol (alcohol is very inagressiv to many plastics, but dissolves) as fat.
Have to make sure that the whole with a soft cloth to make the tape and gently slide through the fingers allow. Not that that still rips.
And note that the tape is dry before you rewind it, not that the role of sticks together.
Antwort von Markus:
P (h) and isopropanol yromane ... does this fit in, yes! ;-)
Isopropene is a solvent, while I was having mild detergent rather then understand something of nonionic surfactants, water-based. So it was at least in my case.
Even I would not take alcohol, especially as it related usein the acetone solvent (2-butanone) contains the denaturation.
Antwort von Gast 0815:
No idea if the tapes attacking alcohol. But I think it is still very much on the substance that causes the pollution, with lemonade, cola, beer etc. I suppose it zuallerst water-soluble substances such as sugar and starch, the glue on the tapes, so I would in a such a case, synonymous with little water and surfactants to try. When we are dealing with things like high-fat vegetable oil etc, but will not bring much, then it will not go without a solvent. When man has fear in front of the impurities / Vergällungsmitteln in methylated spirits, they walk into the nearest drugstore and buy the ethanol in analytical grade. Would, however, test times interesting to know whether and to what degree alcohol DV tapes attacks (one does not have to) with beer, wine, etc. make Schaps.

Antwort von puschel:
So next, I really am now, unfortunately, not yet. That it is not good for the camera, when I no longer running tapes to play there again and again trying to makes sense to me, but what is with the tapes? If the data is destroyed or just for any Low-Beer residues currently not properly run, because the actual data stored on magnetic tapes, but still okay? And does anybody know how I can save the rumzuprobieren with without any chemicals, which may ruin the whole tape? Are there any shops that get to a certain Obolus such tapes and running again?
Antwort von Markus:
So that someone (such industrial cleaning tapes), I have not heard before.
Perhaps it would be a way to an old or inexpensive MiniDV camcorder with the (mechanical) strain for purification. tape in play mode can be passed, then clean the drive and especially the head drum, and leave to go through again. This process may be repeated several times.
If you're lucky, can capture some of the tapes correctly. The shots I would then just copy to new bierfreie tapes and throw away the old ones.
Antwort von wolfgang:
So if even clean tapes, then I would try this in a two-step process:
- Initially with distilled water to avoid such things as Kalklablagerungen too. Water soluble contaminants should be wiped clean.
- Then with pure alcohol (ethanol) or isopropanol synonymous - in a corresponding pure quality, perhaps from the professional chemist or pharmacy. With heavy alcohol vaporizing Vergällungsmitteln is a madness that has to be on the head drum.
Good let dry. Eh go for a short band pieces, you must stop where span - and the man with washes away the solvents. A tape wound can be cleaned barely. Synonymous, I do not know any device, with the If a tape can be passed by solvent baths could. At most you can maybe tape reel off yet, and try to clean in beakers / containers. But the tape to dry without damage and then wind up again unharmed, is certainly a challenge.
Otherwise: I would there always be a pity for the head drum, as the tape has been very important that I risked sowas.
