ABSTRACT:
A method and apparatus for recording and reproducing language learning information from a compact disk. On a compact disk, audio data is recorded separately on left and right channels of a general signal area of the compact disk. Sub-Q data, reproduction information data, and language learning data are alternately recorded between adjacent groups of the audio data recorded separately on the left and right channels of the general signal area of the compact disk. The total number of groups of the recorded sub-Q data is N, the total number of groups of the recorded reproduction information data is M, and the total number of groups of the recorded language learning data is L, where N, M and L are natural numbers and N+M+L does not exceed 75 per second. The reproduction information data indicates the reproduction order of the recorded audio data and the language learning data indicates the contents of the recorded audio data. The reproduction information data is detected from the general signal area of the compact disk. The reproduction order of the L and R channels is determined in response to the detected reproduction information data, and the audio data recorded on the compact disk is reproduced in the determined reproduction order.
