ABSTRACT:
The present invention is a data buffering system for buffering information from an optical recording medium into a buffer memory. The information comprises a main data and a subcode. The system comprises a main target comparator, a correction target comparator and a transfer/buffer module. The main target comparator selects a start main data frame of the main data, and triggers a main data transferring procedure when detecting the start main data frame. The correction target comparator gets a correction main data frame by adding an additional value to the start main data frame, and trigger a subcode transferring procedure when detecting the correction main data frame. The transfer/buffer module transfers and buffers the subcode to the buffer memory and the main data according to the subcode transferring procedure and the main data transferring procedure, respectively.
