In order to record content on a hard disk drive to a source, when a source icon corresponding to the hard disk drive is dragged in a source icon section on a control bar in a display window, an arrow is added above an available source icon corresponding to an MD drive to which the content read from the hard disk drive can be supplied and recorded. An unavailable source icon corresponding to a source to which the content cannot be supplied and recorded is displayed in a grayed-out manner. When the dragged source icon is dropped onto the source icon corresponding to the MD drive, the content on the hard disk drive is read, and is recorded to an MD inserted in the MD drive.
