摘要： 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. The search reproduction control information also includes search information (51: DSI) to search a record position on the information record medium. The apparatus is further provided with a multiplex device (75, 76) for time-axis-multiplexing the processed partial record information pieces and the search reproduction control information.

摘要： An information record medium (1: DVD) has a record track recorded with video information (42, 44) and audio information (43) to be reproduced by a reproducing apparatus (S2). The reproducing apparatus is provided with a read device (80), performs a normal reproduction while relatively moving the read device along the record track and performs a special reproduction, such as a search, a scan and the like, by moving the read device across the record track on the basis of access information to access the video and audio informations. The video and audio informations and control information (41, 51: DSI) comprising the access information are recorded on the record track such that the video, audio and control informations are divided into a plurality of first data group (30: VOBU), each of which is a minimum unit able to be physically accessed, and are divided into a plurality of second data groups (20: CELL), each of which is a unit able to be logically divided in the normal and special reproductions and comprises a series of the first data groups arranged along the record track. Management information (11, PGCI) including a plurality of first reproduction prohibit informations (202), each of which indicates a prohibition of the special reproduction of respective one of the second data groups, is collectively recorded at one portion of the record track.
