摘要：
In this invention, an information recording/reproducing apparatus (1) has an authentication function and directly transfers information to an MPEG board (134), sub-picture run-length board (135), speech coding/decoding board (136) without using a main CPU (111). Thus, information transfer between the information recording/reproducing apparatus (1) and various processing boards (134, 135, 136) can be performed without using a main controller (111), the load of the main CPU (111) can be alleviated and the main CPU (111) can perform another process during the information transfer period.
