GNU tar (and older BSD versions too) have always supported writing to
multiple tapes. You can set a multi-volume tar file with
tar -M -L <tape length> ...
https://www.gnu.org/software/tar/manual/html_node/Multi_002dVolume-Archives.html
I suspect if you got the right length it'll work pretty well. It
might work without specifying it, if it detects the end of the device
correctly, but I'd test it first.
