Large file problem

I have a large file, around 570 gb that I want to copy to tape. However, my tape drive will load only up to 500 gb. I don't have enough space on disk to compress it before copying to tape. Can I compress and tar to tape in one command without writing a compressed disk file?
Any suggestions appreciated.

Thank you.

Does your tar support the z option like tar cvzf [ ..stuff ..] ?

No z option in tar

No, I am on SunOS 5.8

Compress to tar?

I am trying:

compress file_name | tar cvfE /dev/rmt/1 - .

Seems to be working.

I'm doing that now. Does it do a better job of compressing than compress?
