Camera Storage Question at DVinfo.net

Mike Cooper · April 22nd, 2007, 04:01 PM

I have a FX1 and wondered if it's okay to leave the dv cassette tape in the camera for long periods of time while in storage?

Personally, I would never do that. But, I can't think of a reason why not.

More importantly, if you use lithium-ion batteries, insure they are drained if you plan to store for long period (my baseline is over 30 days).

Hi Mike, welcome to DVinfo.

I don't know what the official answer to this question is, but I leave tapes in my Z1 for long periods of time and haven't had any problems. Same thing with my VX-2000 and PDX-10. No problems with these either.

Your mileage may vary :-)

My understanding of concern over such storage methods is the following:

When the tape is loaded into the machine, the drive and track mechanisms spool the tape through the head and capstan componets. The segments of tape that are despooled are no longer wound inside the cassette casing, and as such are more exposed to potential 'expand' and 'contract' cycles due to potential temperature differentials as are common to seasonal or even day/night cycles.

The theory is that even though it is a very small length of tape that may be affected, given enough temperature cycles, you introduce greater potential for tape pinch or tape stretch that could prove problematic to time code or drop outs.

Thats just what I heard, and it sounds logical, but I've never experienced such problems as I never keep the tapes in the cams beyond recording, playback or capturing.

Thanks for all the helpful insight!

Jon's facts are mostly spot on.

I never leave my tapes in.. the way i see it... unless the camera is ready togo RUN AND GUN!!.. why not take an extra step for the heck of safe keeping.

Nothing bad can happen from taking the tape out... but the same can't be said about leaving the tape in...

cameras are sensitive little buggers. any little thing as simple as it might sound to us might make them act up.

I have never heard of this before but it sounds like something I should know. What is the reason for draining Lithium-Ion batteries that will go unused for 30 days?

I am curious as well. I have been told that if a lead acid battery's voltage drops below 11 volts it can be permanently damaged, but I have not heard the same for lithium ion.

Quote from page 99 of the Canon Xl1s Manual:

"If you do not use a battery pack for a period of more than a few months any remaining charge may cause damage to the battery pack, and reduce usage time. To prevent damage therefore, aim to use a battery pack's complete charge before storing."

My first MiniDV camera was a GL1. Either I missed a similar statement in that camera's manual or simply forgot. In any case, I didn't use the camera during the winter for three months. Upon bringing the camera out of storage I quickly discovered two of my three batteries would not power the camera for more than five minutes. Subsequent recharges did not resolve the problem. I finally took the batteries to a local industrial battery store to have them tested. They had been ruined.

Between advice from the battery people and the above quote I arbitrarily chose 30 days as my limit for storing a charged battery. No disappointing surprises so far.

Can you clarify what type of batteries they were? Lead acid batteries will do exactly what you described if their voltage drops below a certain level while in storage.

They were Canon Lithium-Ion batteries.
