Abstract
PURPOSE:To shorten the loss time, and to execute the information processing at high speed by executing an alternate processing against an information defect of one face, to an alternate area provided on the other face. CONSTITUTION:At the time of recording the information to an information recording medium 101 having a recording surface on at least the back face and the surface, respectively, an alternate processing against an information defect of one face is executed to an alternate area 102 provided on the other face. Accordingly, for instance, when the surface defect is generated on a part of the recording surface of the surface side, information is not recorded in an area containing this defect, and immediately the information is recorded in the alternate area 102 provided on the recording surface of the back face. In such a way, a loss time which follows up the movement of a head at the time of alternate processing is shortened, and the information processing can be executed at high speed by that portion.
