In a recording/reproduction device, a type of recording medium which is currently selected is shown to the user on its small built-in monitor screen in a user-friendly manner and, for more user convenience, a background color of the screen is changed depending on the type of recording medium selected by the user. The user can know the currently selected type of recording medium from the screen's background color so it is possible to identify very quickly the type of recording medium even on a small monitor screen.
