Can your old videotape be transferred?
Why do some shops say there may be problems with transferring your old videotape? I'll use the professional format, 3/4 U-matic as an example, but it applies to VHS as well.
* The oxide falls off. The oxide, the metallic coating that contains the magnetic signal, usually loses some of the material, and so, loses some of the signal.
That's on top of the fact that the earlier formats were, of course, lower resolution in the first place (noisy looking). So today, they tend to look worse and are worse because of the loss of material. In other words, over time, you will lose more and more of the image quality.
* The cassette may not play or might "freeze" or seize up. The hubs sit on silicon pads to make the rotation smooth or slippery enough to rotate freely. Heat, cold, bad storage, bad cases, and the tape hubs, that hold the tape, can hit rough spots, rotate poorly or not rotate at all. When that happens, the tape can play poorly or just break while trying to play in the deck. Also, we have seen the splice, the adhesive tape holding the leader and the videotape together, just pop off. Then the tape will no longer play in this cassette.
* Bad tape. Some tape has little folds from being damaged years ago. Some tape has ripples from bad storage, that cause ripples during a "bad" playback. Too much moisture in a basement storage spot? You could have mold on the tape, the inside of the housing. This won't let the little video head play the video without getting clogged or stop the signal all together.
So when a facility says your cassette may or may not "play", they need to look at all these factors and decide if transporting your moldy videotape will cause damage to their video machine as well. Remember, the repair people trained on these old machines are retiring and getting more difficult to find. So are the parts for the decks - so are the machines themselves.
Later we'll talk about ways to store your precious movies and videos to keep them for a very long time - safely.
