A digital audio signal player includes a CD support seat for holding a CD, a microprocessor, a laser pick-up, and a dynamic RAM; a CD supported on the CD support seat will rotate several times the normal speed, and the laser pick-up will read the CD when the microprocessor starts functioning; when the laser pick-up reads a CD, data of the CD will be transferred to and stored into the dynamic RAM; the dynamic RAM is divided into first and second sections, which are respectively used for storing music, which is currently being played, and for storing music that is to be played immediately after the current music is finished; therefore, the first and the second sections of the dynamic RAM can take turns to store music of different compact disks, thus preventing interruption of music playing from happening owing to a change of CD.
