Disk players for allocating pointers to the respective frames of CD data and storing the pointers in a memory, and methods of processing reproduced data of the disk player are provided. According to one aspect, a disk player includes a pointer controller, which allocates pointers to frames of recorded data read from a disk, wherein the allocation of the pointers starts from a first frame following frames having special sub-code synchronization signals and is performed in a predetermined order; a memory, which stores the frames and the allocated pointers; and a memory controller, which controls an operation of writing the data to memory. A pointer is allocated to every frame of the recorded data reproduced from the disk player, and the allocated pointers and the frame data are stored in the memory. The pointers are retrieved and the respective frame data stored in the memory are output. Therefore, the sound continuity can be maintained even in a vibration environment causing jitter.
