(And why?) Yes. But it may not do what you think. I'm guessing (since you don't say) that your tape drive is a DDS-1 model. A DDS-1 tape drive can only write in DDS-1 format, which would put 33% more on a 120m tape than on a 90m tape. 120m tapes are usually written in DDS-2 format, which would put 100% more on them than on a 90m tape. More importantly, if you change your DDS-1 tape drive for a DDS-2 one in the future, you may not be able to read the tapes.
