ROM might be designed using a programmer and then it acts as a "read only" device. This device is used as the book for the CPU in the pc and is named ROM BIOS.

This is achieved by using light to document data in a form that's more tightly packed than the comparatively clumsy magnetic read/write heads a standard drive should control.
