UDF is writable on CD-RW and DVD-RW. ISO9660 is write once. To rewrite a CD-RW containing an ISO9660 filesystem you have to erase it and rewrite a complete new image.
You can leave an ISO9660 disk open which allows writing but old data is then masked not overwritten if you change it so you don't reclaim the space.
