The post-recording region (14) is divided into a plurality of unit regions (24). The reproduction sequence control data (21) is made to have a control data unit (23) corresponding with the unit region (24) by 1:1 relationship. The control data unit (23) is made to have information defining the recording position and the length of the corresponding unit region (24).

Abstract: An information recording medium (100) comprising (i) a first recording layer (layer L0) in which a first part of record data can be recorded and which has such a characteristic that the number of times of possibly rewriting the record data per unit area corresponds to a first number of times; and (ii) a second recording layer (layer L1) in which a second part of the record data can be recorded by use of a laser beam having passed through the first recording layer and which has such a characteristic that the number of times of possibly rewriting the record data per unit area corresponds to a second number of times; wherein frequently rewritten information (FS1), which is relatively frequently rewritten, can be recorded at least in the second recording layer

Abstract: A hologram recording apparatus (300) records record information into a hologram recording medium (100) on which a hologram recording layer (11) and a position information recording layer (13).

Abstract: Even if copy control information in contents is Never Copy (CCI=11) and the like, a recording apparatus which is not in conformity with a copy protection system (CPS) changes the copy control information to Copy Free (CCI=00) and records the contents. A recording and reproducing apparatus which is in conformity with the CPS embeds, in a transmission signal thereof, path information indicating a path through which the contents pass, except for the contents which are originally set to Copy Free (CCI=00). Thereby, when the path information is detected though the copy control information is Copy Free (CCI=00), it is determined that the path information passed through an illegal apparatus, and hence recording can be inhibited.
