A high-speed audio data reproducing method in a CD-ROM player which is suitable for reproducing a high-speed audio data without a reduction in the rotation speed of disc by the CD-ROM player. The method is provided with reading data at a high speed from the disc, performing an audio data error correction for the data to decode the corrected data primarily, determining whether or not the primarily decoded data is audio data, if the primarily decoded data is audio data, selecting the primarily decoded data to temporarily store it into a buffer, reading the temporarily stored audio data at the normal speed and transmitting it, converting the transmitted audio data into an analog signal to make a voice output of it, and if an overflow occurs in the step of temporarily storing the audio data, then controlling a track jump to read in the previously read data again, stopping the track jump control and the temporal store of input data upon occurrence of the overflow, and restarting the temporal store of input data when the data track-jumped and inputted again arrives at the temporarily stopped point. The method further includes the steps of if the data read at the high speed is not audio data, then performing an audio data error correction for the primarily decoded data to decode the corrected data secondarily, selecting the secondarily decoded digital data to store it temporarily, and transmitting the temporarily stored digital data to a host computer at a high speed. |
