- 13. The reproducing apparatus of claim 10, wherein “00h” is used in said first 64 byte portion that is not utilized by said primary text.
- 14. The reproducing apparatus of claim 13, wherein a second 64 byte portion of said primary text information describes primary text in a character set that is not ISO/IEC 646:1983 (ASCII).
- 15. The reproducing apparatus of claim 10, wherein said program management table comprises an item text search pointer number.
- 16. A method for displaying text information, which uses an optical disc having a management area and a data area in which one or more programs have been recorded, said management area including a sequence management information for managing the sequence of said programs and a program management table for managing said programs, said method comprising:preparing first data from primary text information recorded in said program management table; preparing second data from an item text recorded in a portion of said management area; and preparing display data including said first data and second data for displaying contents of said primary text information, wherein said primary text information consists of 128 bytes, wherein a first 64 byte portion of said primary text information describes primary text using an ISO/IEC 646:1983 (ASCII) character set.
- 17. The method of claim 16, wherein “00h” is used in said first 64 byte portion that is not utilized by said primary text.
- 18. The method of claim 17, wherein a second 64 byte portion of said primary text information describes primary text in a character set that is not ISO/IEC 646:1983 (ASCII).
- 19. The method of claim 16, wherein said program management table comprises an item text search pointer number.
- 20. An information storage medium comprising a management area and a data area,said data area being provided for recording data in such a manner that the data is separated into one or more object units and is managed by one or more sequences and at least one sequence includes one or more programs corresponding to one or more cells representing or pointing to at least part of the object units, said management area including a sequence management information for managing program sequences by determining a presentation sequence of said cells, and including a program management table for managing said programs, wherein said program management table is configured to store first text information expressed in character, and a specific area, which is different from a recording area of said program management table in said management area, is configured to store second text information, said program management table is configured to further store search information which includes a search pointer number of the second text information, and said search pointer number corresponding to a search pointer is stored in said specific area, said search pointer which corresponds to the search pointer number indicating a location of the second text information, said first text information consists of 128 bytes, and a first 64 byte portion of said first text information describes primary text using an ISO/IEC 646:1983 (ASCII) character set.
