[conspire] is there a minimum size iso that cdrecord will successfully write to a cd?

I created an iso image of some rpms and html files. I then tried to
write the iso to a cd using cdrecord. Both mkisofs and cdrecord
seemed to finish successfully. When I do an "ls /mnt/cdrom"
I do not see the iso image. Is there a minimum size that cdrecord
can write? Did I make a mistake in mkisofs or cdrecord command
options? Any help, advice, suggestions will be appreciated.

This is the mkisofs command I used:
# mkisofs -v -o name.iso -l -r -V NAME path1/ path2/ > 
./mkisofs-name.iso.log 2>&1
It generated an iso file using ls -l  of size 15859712

the log file shows:

This is the cdrecord command I used to write to the cd:
# cdrecord -v -dev=0,0,0 speed=8 name.iso ./cdrecord-name.iso.log 

the log file shows:
