1. An electronic apparatus having a data playback function, the electronic apparatus comprising:
- a display;
a connection unit through which the electronic apparatus is connected to an external medium storing data that is configured to be played back;
a database creation unit that is configured to extract, in response to the connection of the external medium, retrieval information from a hierarchical structure of the data stored in the external medium for use in retrieving the data stored in the external medium from the external medium to create a temporary database on the basis of the extracted retrieval information, and is configured to, after creating the temporary database, extract retrieval information from each piece of data stored in the external medium and create a normal database that includes information that is not included in the temporary database on the basis of the retrieval information extracted from each piece of data stored in the external medium; and
a display unit that is configured to display the content of the temporary database in the display and is configured to display the content of the normal database in the display after displaying the contents of the temporary database in the display.

9. A method of creating a database of data that is configured to be played back and that is stored in an external medium, the method comprising the steps of:
-
extracting, in response to a connection of the external medium to an electronic apparatus having a playback function, retrieval information from a hierarchical structure of the data stored in the external medium for use in retrieving the data stored in the external medium; creating a temporary database on the basis of the extracted retrieval information; after creation of the temporary database, extracting retrieval information from each piece of data stored in the external medium; and creating a normal database that includes information that is not included in the temporary database on the basis of retrieval information extracted from each piece of data stored in the external medium. - View Dependent Claims (10, 11, 12, 13)
