When overwrite inhibiting is directed, flags (oblique lines in FIG. 4) for indicating the overwrite inhibiting are set in all the sectors between a sector 51 in which the overwrite inhibiting is directed in a buffer area and a certain preceding sector 52 and also, decoding is continued from the next sector 53 of the overwrite inhibiting area. At this time, when buffering is completed to the one preceding sector 50 of the overwrite inhibiting area, the buffering jumps the overwrite inhibiting area and is continued from the next sector 53 of the overwrite inhibiting area. Also, in decoding, when a special reproducing mode is directed, a decoding position (a position of a sector 54) at that point in time is stored as the present position and thereafter, the decoding of the overwrite inhibiting area is performed.
