I have 10 VXA Tapes to make a forensic copy of.

i'm planning to use DD for the acquisition of these tapes, but since it's the first time i have to deadl with such media, are there things i need to take particular care of?

for example, if i make a dd image of the tape, can i then use dd to write the content back to a new tape?
can i access the content of the image to extract the data out of it?

is it possible to mount a dd image of the tape in loopback to check the content? or (as i think) it's not possible?

i've also read a topik about tape forensics on this forum and someone explained something about block-size that must be the same for both the source and the destination, but i can't find informations about these tapes block size anywhere, is there a way to obtain such information?
