摘要：
An information recording apparatus (SS1) is provided with a signal process device (72) for applying a predetermined process to record information (R) including video information and other information to be recorded onto an information record medium (1: DVD), to thereby output processed record information (Sr) composed of a plurality of predetermined information units (30: VOBU). The signal process device also generates first recording position information for respective one of the information units. The first recording position information indicates recording positions on the information record medium of the information units corresponding to reproduction times of the record information within a predetermined range before and after the respective one of the information units. The signal process unit further generates second recording position information for respective one of the information units. The second recording position information indicates recording positions of the video information to be reproduced within the predetermined range. The information recording apparatus is also provided with: a multiplex device (75, 76) for multiplexing the processed record information, and the first and second recording position informations by each of the information units.
