What steps are involved in writing a CDROM?
A growing subset of machines (including nearly all the machines in the basement lab) have (re)writable CDROM nd DVD drives. Obviously, writing to a CD will not work well unless you are using one of these machines. Writing CDs is a 2 step process (or a 3 step process if you include going to the store (or Rm 101B) to buy a blank CD-(W)R disk). First a disk image must be created. This is file that contains the image of what will eventually be on the CD. Since you can only write once to CDs you cannot simply add files one at a time. The entire filesystem including the bookkeeping parts that you don’t generally realize are there must be assembled before the CD can be written. A filesystem image assembled in this way is usually stored in a file with a “.iso” suffix. The second step is to transfer this filesystem image to the CD. You need only be vaguely aware of these two steps if you choose to make your CDs with nautilus file manager application – aka “the easy way”.
