Abstract

A reproducing method for obtaining character information in a plurality of languages from a CD-ROM drive and automatically displaying the character information in the most proper language on a screen. An optical disc drive and a host computer 53 are connected through an interface 42. The drive has a servo and signal processing portion 30, a system controller 41, and a CD-ROM signal processing portion 50. The servo and signal processing portion 30 reproduces data from a disc 21. The system controller 41 controls the entire operation of the drive. The drive sends back return data corresponding to a read TOC command to a computer 53. The computer 53 determines whether or not CD-TEXT data contains character information of a language corresponding to the country information of the OS. When the CD-TEXT data contains the character information, the computer 53 displays the character information. Otherwise, the computer 53 displays character information in a predetermined language (English of block 0).

Claims

1. A reproducing method for causing a computer operating according to a predetermined operating system to obtain data reproduced from a recording medium loaded to a drive of a computer, the recording medium being formatted in such a manner that a program and character information associated therewith are recorded on the recording medium, the character information being written in a plurality of languages, and including a plurality of language codes corresponding respectively to the plurality of languages recorded in a management area of the recording medium, the reproducing method comprising the steps of:

obtaining data reproduced from the management area of the recording medium by the drive including one of the plurality of language codes;

detecting one of the plurality of languages of the character information associated with program recorded on the recording medium corresponding to the one of the plurality of language codes obtained in the step of obtaining;

detecting country information of the predetermined operating system of the computer;

determining whether the character information of a language corresponding to the detected country information of the predetermined operating system is recorded on the recording medium; and

displaying the information when the character information is determined to be in the language corresponding to the country information recorded on the recording medium.

2. The reproducing method as set forth in claim 1, wherein the displaying step further displays character information in a pre-designated language when the character information in the language corresponding to the country information of the predetermined operating system of the computer is not recorded on the recording medium.

3. The reproducing method as set forth in claim 1, further comprising the steps of:

displaying a list of the plurality of languages included in the character information associated with the program recorded on the recording medium and corresponding to the language codes; and

selecting one language from the list.

4. The reproducing method as set forth in claim 3, wherein the list of the plurality of languages is one of a plurality of menus.

5. A recording medium from which a computer using a predetermined operating system reads a program and a reproducing method for causing the computer to obtain data reproduced from the recording medium loaded to a drive of the computer, the recording medium being formatted in such a manner that a program and character information associated with the program are recorded on the recording medium, the character information being written in a plurality of languages, and including a plurality of language codes corresponding respectively to the plurality of languages recorded in a management area of the recording medium, the reproducing method comprising the steps of:

obtaining data reproduced from the management area of the recording medium by the drive including one of the plurality of language codes;

detecting one of the plurality of languages of the character information associated with the program recorded on the recording medium corresponding to the one of the plurality of language codes obtained in the step of obtaining;

detecting country information of the predetermined operating system of the computer;

determining whether the character information of the language corresponding to the detected country information of the predetermined operating system is recorded on the recording medium; and

displaying the character information when the character information is determined to be in the language corresponding to the country information recorded on the recording medium.
