You can create an iso9660 filesystem using the 'mkisofs' program. It has
a lot of options, so you had better just read its manual page rather than
me trying to explain it here. You can create the filesystem as a file on
your hard disk, and mount it using the loopback device.
To use the loopback device, you must compile loopback filesystem support
into your kernel, or use the standard Debian kernels. A loopback is
mounted in much the same way as any other filesystem:
mount -o loop <iso image file> <mount point>
Again you should have a look at the manual page for the 'mount' program.
There is a short section dealing with loopback.
