Hello Patricia. IMHO there are two Bacula safe ways to write on multiple tabe
library drives at the same time:
1. Having Maximum Concurrent Jobs in each device on bacula-sd (probably is what
you have). If you want to avoid tape spreading just increase the maximum value
for each device to more than all Jobs submited to Pool1.
2. Don't using Maximum Concurrent Jobs but scheduling Jobs for different pools
at a given time.

I don't linke using different media types for the same kind of media, but it's
my personal view.

Never tested but seems possible. Of course the Scratch pools gotta have unique
names:
Pool Resource (Bacula Manual):
ScratchPool = pool-resource-name
This directive permits to specify a dedicate Scratch for the current pool. This
pool will replace the special pool named Scrach for volume selection. For more
information about Scratch see Scratch PoolTheScratchPool section of this
manual. This is useful when using multiple storage sharing the same mediatype
or when you want to dedicate volumes to a particular set of pool.
