Someone recently told a clubroom full of filmmakers a long daitribe of how dangerous tape head cleaners are.

There were scare stories about effectively dragging coarse sandpaper over your camera heads, and that sort of thing, and even a single use of a cleaning tape will wear out heads!

I know tape head celaners are abrasive, but there are varying degrees of abrasive! On my old TRV 900, I probably used a tape head cleaner once or twice a year, and that camera lasted 8 years, so I doubt the head cleaners are that abrasive!

I'd like to correct him with citations or online evidence, like manufacturers statements saying that you should clean heads every 40-50 hours, or something like that.

Or is he correct, and I shouldn't even place my camera next to a cleaning tape in case it gets worn out! :-)

He is partially correct in the fact that tape cleaning tapes are very abrasive, and the sandpaper analogy is accurate.

However, it's overuse of tape leaning cassettes that lead to tape head damage.
If you use your cameras a lot, then cleaning the tape heads every 2-3 months is advisable. If you infrequently use your camera, then once or twice a year should suffice.

That being said, I prefer to clean my tape heads and pinch roller, manually using cleaning chemicals, and chamois swabs. It's much less abrasive, and I do this once a year.

Well, if it is a choice of junking the camera/having the heads replaced at great expensive because you can't play a tape anymore or running a cleaning tape for 10 seconds, I know which option I'd take.

Personally, with DV mechanisms, I'd never dare attempt to clean the heads etc manually as I might an audio cassette deck unless I remove the mechanism so that I can get at the parts from the right directions and get plenty of light in there. And that can be a very fiddly (if interesting) experience.

The trouble is, there's lots of posts stating opinions online, (no offense guys) :-) - I've been filming for 15 years myself, but I was after any manufacturers recommendations or something official? Hs anyone seen anything?

thanks! :-)

According to my official Sony PDX-10 service manual, you should use a cleaning cassette during routine use of the unit (10 seconds) when the picture quality indicates cleaning is needed and use the swab/fluid method during scheduled servicing or any other time the unit has to be serviced. In the swab/fluid case, it should only be done with specific swabs and fluids and with completely unobstructed access to the head. It is necessary to move the swab horizontally (never, ever vertically) and manually rotate the header counter-clockwise. This is virtually impossible to do without disassembling the unit to get at the transport mechanism module.

Service manuals are the oracles.

Thanks john, thats great, although they're being a little vague.. :-)

I'm sure I read in something a few years ago, that they suggested every 30-40 hours of operation, but I can't remember if that was a camera manual or a tape cleaner instructions.

I run a Sony service center and I don't recommend ever using a head cleaning tape. Bring it to a service center every 6 months or so for a good manual cleaning.

Chris: please forgive my analogy but here goes:

How often does one need to bathe? Does one bathe when one notices that he/she is beginning to become odorous? When one feels "less than fresh"? As a part of a regular personal maintenance routine?

I shower every morning so I feel confident that I will not offend the sensitivities of others' olfactory senses. If I've been working in a hog barn or race track, I'm likely to shower again at my first opportunity.

Now: replace "shower" with "clean heads", change "every morning" to "every 20 or so head hours" and change "shower again after the hog barn or race track" to "clean heads after exposure to harsh environmental conditions".

I personally can't wait until dropouts appear in my work to clean heads. I need to be more proactive. Is every 20 hours excessive? Not sure but I haven't had a dropout in 8 years since I started this regimen and my last camera was still going strong after 7 years.

hah! I bet you do! :-)

I recommend that my clients make a new corporate video every month too, but hey ho, you can't have everything!

Scot does bring up a good point: there is more to protecting the integrity of the tape path than just cleaning heads. There are a lot of very precise moving parts in there that can also become "gummed up" or littered with tape oxide and other nasty bits.

Everyone's comments are feasible in theory, however I'm still looking for good technical facts.

With my TRV 900, I used it until the whole mechanism wore out and collapsed, and had to be replaced, and inspite of running a "sandpaper-covered cleaning tape" through it about twice a year, the head still managed to out-last the mechanism.

Was I just incredibly fortunate, or could people be exaggerating the abrasiveness of cleaning tapes? :-)

The technical "facts" are quite vague. It depends on how you use your camera: environment (hot, cold, sandy, dewy), choice of tape stock, how often do you re-use tape...

How much fuel does it take to get from Miami to Los Angeles? Are you driving a dumptruck or a hybrid car? Are you flying a jumbo jet?

I understand your frustration but I don't think there is a catch-all answer or solution.

Yes, there are facts available online. IN fact, you can google most user manuals to any camera.

The facts are on page 110 of the Canon XL2 manual.


Basically 'clean the heads' when they are dirty. Clean them with a commecially available 'dry' video head cleaning cassette.



You won't find a specific number of hours of reccomended frequency - as your mileage may vary.

Shaun, I MUCH preferred your previous analogy. :-) :-)

The tape either runs over the heads or it doesn't! Nobody says, "Don't lend your tapes to Chris, he's a heavy user - he'll wear out your tapes in no time. Lend them to steve - he'd much more sympathetic with tape usage" :-)

I appreciate EXTREMES of cold,salt,humidity etc will have an effect, but in normal use, tape usage is measured in hours, and that's it... isn't it?

I just have a big problem with anyone saying cleaning tapes are VERY ABRASIVE. I've felt sandpaper, I know very abrasive. I understand about microparticles, and under a microscope, cleaning tapes appear to be very rough, but camera heads are not made of feathers, or paper! They're made of metal! :-) Over 100 hours of cleaning tape use maybe you'll see a difference, but I really can't see much happening in 5 seconds of use! :-)

I just felt it was wrong of this old-timer telling a roomful of impressionable teenage filmmakers that holding a cleaning tape next to their camera will ruin it for ever!

I wanted to disprove his statements with facts rather than my opposing opinion, but I'm thinking I can either say nothing or just state a different opinion.

The only answer is to read the manual for your camera. Different cleaning tapes do different things and affect each camera differently.

My FX1 manual says to only clean when the camera asks you to. I have also read that you should do it before changing to a different brand or model of tape as the lubricants are different.

I plan on doing it at least once a year as we film weddings and really dont want dropouts. Any more than that would be daft.

Whos the expert? Us or the people which designed and made the camera?

Back in the Betacam days a Sony technician who worked on the broadcast line recommended using the head cleaning tape every 50 hours, for about 5 seconds. I did that and always got maximum head life from the Betacam camera, and same for DVCAM, and I do it now for HDV with Canon cameras. I used to do manual cleaning too because I shot in lots of dusty enviroments, but so far haven't had to do that in the DVCAM/HDV world. Things are a lot smaller inside these cameras now so I don't think I want to go there.

And I think most of us are clumsier than we were back in those days too...

Meaning no disrespect, but I vote that I'm the expert when it comes to evaluating EXACTLY how my camera has been used, how important my footage is to me and how long my camera needs to last me before it's paid for itself.

Chris, we had the same sort of question on the VX2k yahoo forum - 'when should |I use the cleaning tape?' I replied that it depended on shooting conditions, whether you changed tape brands, how many hours of tape had passed the heads. I told the poster that from my experience (TRV900, VX2k, Z1) there was little harm he could do.

The next day the same poster wrote again. He said the cleaning tape worked very well, was quite expensive but he'd go out and buy another one for the next time his heads needed a clean. Little cogs ticked in my brain. 'You ran the cleaning tape till it came to a stop, right?' I said.

'Sure' he answered. 'Was that wrong?'

Of course it made me shiver to contemplate the heat build-up in his delicate heads, but a few more postings calmed me - his camera performed as good as new but he's remember next time to do a 10 sec burst max. He probably shaved off 500 hours but so what?

The moral is that yes, it's abraisive but not in the sandpaper way. And heads are tougher than we think. And you should think on this when you buy secondhand; there are some do-lallys out there.

tom.

I don't think you can really predict a cleaning schedule. If you have a squeeky clean tape path in your camcorder, there is no guarantee that the very next new tape you stick in your camcorder won't cause a head clog.

Obviously, the best (most inconvenient and expensive) method is to do as Scot says and have it cleaned professionally every 6 months. But beyond that, I would only use a head cleaning tape if you have some indication that your camcorder needs attention. If I am confident that the tapes I am using are virtually free of drop outs and I see a couple of drop outs from one particular tape, I am going to run the cleaner tape for 10 seconds. If I see more issues and the head cleaning tape doesn't resolve them, I will take it to the professional, rather than running the cleaner tape repeatedly.

I use a JVC HD100 and the camera tells me when to use the head cleaning tape. It flashes across the screen, "Cleaning Needed" it is about the only time I do what I am told.... I did notice the one time I tried to ignore it I had a section of footage seperate into about a hundred small sections. I assumed the two events were related.
