  • Patent number: 6148138
    Abstract: An information recording apparatus (SS1) is provided with a signal process device (72). The signal process device divides record information (R) into a plurality of partial record information pieces, and applies a predetermined signal process to each of them to output processed partial record information pieces (Sr, P, 42, 43, 44). The signal process device also generates and outputs search reproduction control information (Snav, 41: NAVI-PACK) on the basis of control information (Si) to control a reproduction of the record information inputted from the external. The search reproduction control information includes time information (50: PCI), which indicates a reproduction time for each of the partial record information pieces.
