I had searched for it 3 years ago ando found out 
the allowed number of mount / read /write passes to be very high,
with the conclusion for my usage I do not have to carry about at all
(in contrast to DDS3 tapes where the limits were very, very low).

I cannot support you with exact information, 
but as far as I can remember I believe 30.000 
or some another very high number of read/write passes are allowed.

I am sorry I have no idea about the aging.

You may want to ask IBM or Fuji or search on www.lto.org

Betreff: Retiring LTO tapes


Hi,

I've a simple question for the group, we are using a mixture of IBM and
FujiFilm LTO1 tapes in a IBM3584 library.  Does anyone have a policy (or
your thoughts) on retiring tapes, i.e. after X number of read/writes or X
years service?

Looking forward to your responses

regards
