TDK Warning

Subsequent to my last post re TDK SA shedding, i received 6 GX 35-90B all shedding white powder and 4 TDK LX35-90B shedding the same.
They came from different sources.

In 1975 I purchased a reel of top line TDK tape. It didn't play well on my Sony RTR with lots of dropouts. However it also left a whitish deposit on the transport. In any event my Sony never fully recovered from that TDK reel and ultimately it caused me to loose patience and toss the entire deck out the window (really).

I've got a GX50-120BM on my RS-1506US right now with no sticky shed issues ....

I've only got 1 TDK reel tape- the LX I think. I'll have to check it out and make sure its usable.

I'm not aware of any TDK tapes being afflicted with SSS.

White powder is usually indicative of lubrcant breakdown, or more likely-mold/fungus and/or oxidation from the reel.

That's pretty rotten to hear that some TDK is now dieing a slow death too. After reading your post, I've just checked three 10.5" reels of LX that I bought in the 80's new (therefore I know the history) and they all have a white powdery substance on the edge of the tape. Not tried playing one as the cleanup is a nightmare

Edit: Maybe our wonderful british climate may have something to do with this?

It doesn't appear to be any kind of sticky shed, rather than a dry white powdery residue that builds up on the heads and entire tape path.

I reported this in my recent thread "whats this crud". I was using TDK GX tape and it caked up my deck. I'm thinking of launching the tape and just saving the reels.

I also asked the question as to whether or not this residue could cause any harm as in the case of the previously mentioned Sony?

I have had other tapes showing signs of white on the packed reel that didn't deposit, i guess that was mold. These TDK tapes were all clean with little or no signs of previous use, some had a few tracks recorded. There were two brand new unopened GX35 that i opened subsequently and they also deposited the white powder, its not difficult to remove from the heads. I am going to try a few passes to see if it stops.
On the used tapes when trying to record on them before the heads were dirty they suffered from poor frequency response, and are really unusable.

Improper storage is causing it. By the way I was told by a lot of Vietnam vets that they got into RTR because records didn't last long in the climate of South Vietnam. At least that's how I understood it.

Hmmm, okay, no white residue on mine then. As to the rest of the question, chances are if the white stuff gets on your heads and tape path, then a good cleaning with 99.9% isopropyl will kill it or clean it away. Of course, anytime I'm suspect of a tape with a good reel then the path is clear: tape can be replaced, the reels are worth keeping. You may want to clean it well after you remove the tape path. A home dishwasher would probably be marvy unless there are some delicate decals emprinted. As to harming your Sony.... probably not unless you let the residue sit there for a long long time.

What is the correct or at least best method for storing tape in the home environment for those of us that do not have a climate controlled room?

Once a tape exhibits this syndrome if it is a binder break down are they goosed or can they be salvaged?

I would really like to know the answer to this also, especially as my entire collection of 456 went down the pan many years ago, along with some really nice material. Not sure if my wife will allow me to extend the house to incorporate a 'tape chamber'

Dark. Small space but enough space to allow air circulation. Vertically stored. I.e. - the proverbial "closet". Avoid temperature extremes and high humidity.

Has anyone tried the nu finish trick on these yet? It brought back a couple of my pre-records that were quite moldy and sounded horrible. It might just do the trick. What you got to loose?

In many years of calibration and TDK tape use they have always held up.In fact the SA tape seems to be better reaction wise to the XLII on open reel machines as the XLII have a lot of drop outs with no physical sign of wear on them. Of course this is the long out of production EE tape.
I would try Nu Finish on them if you can get some. If it is Mold, the Nu Finish will clean it off to the most part. If the lubrication is failing or fatty substance is surfacing - this subject I leave to Wilhelm, the Nu Finish should resolve the issue- the only tape I threw away recently was a 1/2" reel of Ampex 456 that had edge damage as well as stickiness. I could fix the stickiness but there is nothing to be done about the edge damage.
I don't think TDK sold the same amount of tape in the reel to reel line as did Maxell but I would not say it was a poorly made tape or that it has a long history of defects.
Just my point of view.

TDK tape is worth saving. Audua is OK, but the LX/GX are phenomenal.

From what I've read this is a lubricant issue that only affected later production runs. I have some LX I just got that is fine, I have some GX that has the powdery residue. My dad has some GX he bought in '81 that is okay & some he got in '86 that is bad. (In fact, he was the first person to tell me about it.) I also have some SA with no issues.

I scored a couple of reels of TDK recently (used) - Some Adua and some LX. Not bad tape - didn't see any evidence of SSS or deposits - just didn't sound great. I tried it on a both my RT-2022 and my CX-822 (both 2-track machines).

I was ready to pull the BIN trigger on some GX yesterday but chickened out and went for a 2-pack of Maxell 35-180B instead ($56 for both - which is my comfort zone). I've never (yet!) had an issue w/Maxell.

Opposite on cassette, I've always used (back then and now) SA and SA-X and preferred them over the Maxell equivalents.
