I suggest using the following command to write the file
	find . -depth -print | cpio -o | compress | dd bs=8k of=/dev/rmt0
	(I use 8k on my cartridge but use whatever blocking factor is
		appropriate for your system.)

To uncompress the tape file, use the following command:
	dd if=/dev/rmt0 bs=8k | uncompress | cpio -ivdum (or whatever cpio 
		options you need).

Good luck!
