Abstract
A recording medium managing apparatus and method of managing recording medium are provided. To enable identification information for identifying recording medium to be assigned only once to an area for recording a regular signal and manage a content item on the recording medium using this identification information. Disk identification information can be recorded in a lead-in area of a disk 200. When a flag indicating whether or not disk identification information is recorded indicates that disk identification information is recorded, new disk identification information is prohibited from being recorded. A content management table 520 links and stores disk identification information and attribute information of content items. A menu generating unit 150 displays a menu based on the content management table 520. When a recording destination disk to be used for recording a content item is not loaded, the content item is stored in a suspended-content storing unit 540 until the recording destination disk is loaded.
