There are usually two reasons that people prefer write once DVD or CDs: They're cheaper. They can't be overwritten accidentally.
In general, no. CD-ROM is read-only. You can only read from it after a manufacturer writes to the disc permanently. However, there are recordable CDs (CD-R), which allow you to write once. And, there are rewritable (CD-RW), which allow you to write and erase many times. The same goes for existing DVD technology (DVD, DVD-R, DVD-RW).
