When requesting a plurality of title list information recorded in (10), the microcomputer 13 operates the menu graphic generator 14 to control the title list information and the reduced image recorded on the optical disc 10. 2, the output is displayed in a list form.

In addition, in the case of selecting and designating any one reduced image among a plurality of reduced images outputted and displayed in the form of a list, the playback operation is performed quickly by accessing a start recording position of a title corresponding to the reduced image. Since the user checks the title name, the recording time, and the reduced image which he / she wants, the user can select and specify an arbitrary reduced image to easily select and play the desired title.

However, in the general optical disc apparatus, only the optical disc inserted and mounted in the apparatus can perform the above-described list information and reduced image display operation, so that a user having a plurality of optical discs selects and plays a desired title. In this case, since one optical disk is sequentially inserted and inserted into the optical disk device, the above-described list information and reduced image display operations must be performed one by one, so that the user may feel inconvenience in using the optical disk or the title. The problem that takes a long time occurs.

Accordingly, the present invention was created to solve the above problems, and in various optical disc devices such as DVD players, DVD recorders, etc., list information and reduced images respectively recorded on a plurality of optical discs, one index disc (Index) Disc indexing and retrieval method in an optical disc device for efficiently recording and retrieving the list information and the reduced images recorded on the index disc and allowing a user to easily select a desired disc or title. It is to provide the purpose.

According to an aspect of the present invention, there is provided a method of creating an index disk in an optical disk apparatus, the method comprising: capturing list information and a reduced image of an optical disk inserted into the apparatus and storing the same in a memory; And recording the list information and the reduced image stored in the memory on the index disk inserted into the apparatus.

In addition, the index disk search method in the optical disk apparatus according to the present invention, the first step of reading the list information and the reduced image for each disk recorded on the index disk to display the screen; Selecting and specifying one disc reduced image from among the disc reduced images displayed on the screen; And reading out the list information and the reduced image for each title corresponding to the selected designated disk from the index disk and displaying the screen.

Hereinafter, a preferred embodiment of the index disk creation and retrieval method in the optical disk apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

First, the index disc creation and retrieval method according to the present invention can be applied to various optical disc devices such as a DVD player or a DVD recorder. For example, the microcomputer 13 of the DVD player configured as described above with reference to FIG. ), The menu graphic generating unit 14 is operatively controlled in response to a user's request, so that the title list information and the reduced image recorded on the optical disc 10 inserted and seated in the apparatus are shown in FIG. In addition to displaying the output in the form of a list, an index disc creation menu item newly defined by the present invention is additionally displayed.

On the other hand, in the microcomputer 13, when the user selects and selects an index disc creation menu item, the microcomputer 13 captures various list information and reduced images recorded on the optical disc, and stores them in the memory 15 in the device. After performing a series of download operations, a guide message for inserting a preset index disk is displayed.

When the user replaces and inserts the index disk into the device, the microcomputer 13 compares and checks whether the list information and the reduced image stored in the memory 15 are previously stored in the index disk. A series of index disk update operations for storing list information and reduced images on an index disk will be performed.

4 is a flowchart illustrating a method of creating an index disk in the optical disk apparatus according to the present invention. For example, the microcomputer 13 is inserted into the apparatus as described above with reference to FIG. In the operation mode in which the list information and the reduced image recorded on the optical disc 10 are displayed on the screen (S10), it is monitored whether the user selects an index disc creation menu item (S11).

On the other hand, when the user selects and designates a menu item other than the index disk creation menu item, the microcomputer 13 performs a corresponding operation corresponding thereto (S12), and the user selects the index disk creation menu item. In the case of selection and designation, a series of download operations for capturing various list information and a reduced image recorded on the optical disc 10 and storing them in the memory 15 are performed (S13). As shown in the figure, the list information and the capture status of the reduced image are displayed on the screen, so that the user can recognize and wait.

In addition, after the list information and the reduced image are both stored in the memory as described above, the microcomputer 13 controls the menu graphic generator 14 to display a guide message requesting the insertion of the index disk. For example, as shown in FIG. 6, for example, as shown in FIG. 6, a message requesting Index Disc Insert is displayed on the screen along with a state display in which both list information and a reduced image are captured.

In the microcomputer 13, when the user replaces and inserts the index disk (S15), the information stored in the index disk is compared with the information stored in the memory (S16), and the list information stored in the memory is checked. And whether the reduced image is new information not recorded on the index disk. For example, the disk ID Disc_ID stored in the memory is compared with whether the index image is already stored on the index disk. It is determined whether or not (S17).

On the other hand, if it is determined that the information is not new information, the microcomputer 13 controls the menu graphic generator 14 to display a message indicating that the information is already stored, and then does not update the index disk. (S18), when the determination result is new information, the microcomputer 13 reads the list information and the reduced image stored in the memory 15, and sets up a series of index disks for storing them separately on the index disk. The date operation is performed (S19).

Accordingly, the list information and the reduced images respectively recorded on the plurality of optical discs can be recorded and stored on one index disc. The microcomputer 13 then records the index information on the index disc at the user's request. The list information and the reduced image for each disc are displayed on the screen in the form of a list in which a user interface is available.

For example, as shown in FIG. 7, the list information and the reduced image for each disc are displayed along with detailed menu items (eg, Title, Chapter ..) that can be selected by the user. When the title menu item is selected while the cursor is moved to the reduced image (Thumb 5) representing the fifth disc Disc 5, the microcomputer 13 selects the fifth disc Disc 5. After the title list information and the reduced image representative of each title are read from the index disk, the title list information included in the file is displayed in a list form as shown in FIG.

Therefore, the user can easily search for a title recorded on one optical disk among several optical disks by using the index disk, so that the time required for searching for a desired disk or title can be reduced efficiently. Will be.
