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).
