To surely record the first contents even if the end time of second contents distributed before the first contents is extended when the first contents are reserved for recording.

The information recording device detects the characteristics of the signal actually broadcasted during the time from rough time t1 to the time after the elapse of prescribed time when video tape recording of a reserved program 92 scheduled to be broadcasted from the time t1 to the time t2 is reserved. When the characteristics of the detected signal are discriminated that they match the characteristics of the signal corresponding to a preceding program 91, the time t4 when the reserved program 92 actually ends is estimated by assuming that the preceding program 91 is extended. The end time of the reserved program 92 is extended from the time t3 to the time t5 on the basis of the estimated time t4. The device and the method for recording information, the recording medium, and the program can be applied to a video tape recorder to record a television broadcast program.
