In order to enable the user to easily search for the recorded title, recording information of the title and identification information of the recording medium are recorded and managed in the memory 16 as the Record List information. ,

For example, as shown in FIG. 2, when a digital broadcast program is recorded on a rewritable Blu-ray Disc (BD-RE) with a title of "X-Man", the microcomputer 14 performs a recording on the title. Title name (e.g. X-Man), recording date and time (e.g. 20003/07/07 22:00), channel information (e.g. 11), and file name (e.g. 00110.m2ts) in the recording medium, In addition to recording in the memory 16 as recording information, a unique disc ID (e.g. XXXX) and a disc name (e.g. BDRE01) assigned to the rewritable Blu-ray Disc (BD-RE) are provided. In conjunction with, it will be stored and managed as a recording list.

On the other hand, when the microcomputer 14 performs a recording list display operation according to a user's request, the microcomputer 14 reads and references the recording list information stored and managed in the memory 16, and the OSD generating unit ( 15), the OS video of the recording list for each title is output and displayed on the screen of an external connection device such as a television.

For example, in the microcomputer 14, as shown in FIG. 3, each recording is performed on the basis of recording information such as title name, recording date and time, channel information, and file name in the recording medium for each title. By displaying the list in the form of a list, it is easier to search for a specific title desired by the user.

In addition, in the microcomputer 14, titles that can be currently selected by a user are highlighted by differently highlighting colors, or by additionally displaying icons (Icons) representing the recording medium, so that a title desired by a user is displayed. It makes it easy to identify which recording medium is recorded.

When the user requests playback of any one title, the microcomputer 14 determines whether or not the recording medium recording the title is inserted into the apparatus. If the ID of the recorded recording medium is 'XXXX' and the ID ('XXXX') of the rewritable Blu-ray Disc inserted in the device, the recording position of the title is recorded on the BD-RE. At the same time, the OSD generating unit 15 is controlled to display a guide message indicating that playback is possible and title search is performed, as shown in FIG.
