This part includes various categories and various images and characters corresponding to each category in order to widen the selection. Since each image has a large data size, as shown in FIG. 4A, control data (4) It is stored separately in the rear stage (IMG 1 to IMG n).

5 is a flowchart illustrating a method of recording and modifying a menu according to the present invention. The menu recording and modifying method of the present invention utilizes a data structure including a specific data file in an optical disc apparatus capable of supporting random access and recording and modifying.

First, the user decides whether to record or modify. The recording of the new menu for the menu image and the menu characters and the modification of the existing menu have the same processing steps (processing steps).

After starting the modification step (step 50), if the menu image is determined to be corrected (step 521), all the category data (see Figs. 4B and 414) existing in the control data are displayed on the screen. If the corresponding image category is selected (step 522), various menu images of the selected menu image category are displayed (step 523). If one menu image is selected from the displayed menu images (step 524), the relevant information in the information file (see FIGS. 3 and 31) is modified to produce the selected menu image (step 525), and the operation is completed (step 59). ).

If the modification of the menu character is selected (steps 521 and 541), this also displays all the category data (see Figs. 4B and 414) existing in the control data. If the corresponding 'character category' is selected (step 542), various menu characters of the selected menu character category are displayed (step 543). If one menu character is selected from the displayed menu characters (step 544), the user is asked whether to edit the selected menu characters in a different form (step 545). To edit other types of menu characters, go through a separate editing process (step 546), change the relevant information in the information file (see Figures 3 and 31) (step 547), and if you do not edit the menu characters, then the information file After modifying (see FIGS. 3 and 31) (step 547), the operation is completed (step 59).

As mentioned above, the above-described modification process is the same when the new menu is recorded in the information file (see FIGS. 3 and 31). When the new menu is recorded, the relevant information and data are registered in the information file (see Figs. 3 and 31).

In addition, the above-described embodiment includes a step of editing in a new form only when the menu character is corrected (recorded). However, in the case of a menu image, the new edit step may be added if necessary. However, since the present invention has prepared various forms to simplify recording and modification, new menu image editing other than the various prepared forms is said to be less efficient, and in the case of menu letters, other forms of editing are relatively simple. It adds a step (545,546) asking whether to edit. In addition, if you want to cancel the current work, you can also include a cancel function so that you can cancel and finish the work up to that time.

As described above, the method of recording and modifying a menu according to the present invention includes a variety of images and characters prepared in a data structure including a specific data file in an optical disk apparatus capable of moving to a desired point and recording and modifying. By using this, the user can easily record and modify the desired menu image and menu text.
