It helps if people read the FreeBSD handbook:

"tar tf /dev/acd0" would give you the contents of the junk.tar file

There are lots of possible filesystems one could put on a CD.
ISO-9660 is a common choice, and even a reasonable default, but if
you want to write files directly to the CD as a block-access device,

Actually, "man burncd" does give a bunch of examples-- it has an
entire section of them-- and finishes with the comment:
In the examples above, the files burned to data CD-Rs are
assumed to be
ISO9660 file systems. mkisofs(8), available in the FreeBSD
tion, as part of the sysutils/cdrtools port, is commonly used
ISO9660 file system images from a given directory tree.
