The recording control part 14, when it receives a demand for reservation, issues a program identifier for the reserved program. The program identifier is uniquely identifiable in the data recording unit, or in a given physical or logical scope which comprises the data recording unit, or is absolutely identifiable. Some examples of program identifiers are shown in FIG. 2 in a program ID column 21 of a management table 20, �26579�, �96156� and �35948�.
Temporary or actual ensuring of a recording area in this stage is virtually carried out by the recording control part 14, which manages the data recording part 15, using variables which show the state of the recording medium existing in the data recording part 15. Or, ensuring of a recording area is also realized by changing attribute of one or a plurality of designators, which indicate the position at which the recording medium exists in the data recording part 15, from �vacant� state to �ensured� state. It can also be realized by writing virtual data expressing an �ensured� state onto one or a plurality of recording media of the data recording part 15. Or, these methods may be used in an assorted manner.
The management table 20 in a managing device, as shown in FIG. 2, is formed with the following elements, the program ID 21, related information 22 and a recorded position 23. The recording medium 24 is a disk-like recording medium having a data recording track in the form of a concentric circle. A position is indicated using a track number. The recording area corresponding to program ID �26579� (recording track 25) is ensured as an actual area because confirmation of recording has been completed. A recorded position, shown as �01350425�, is composed of three elements, a medium number �01�, a starting track �350� and an ending track �425�. The table of program ID �35948� is in the middle of the course with only issuance of program ID and inspection of the recording area finished. The area ensuring the recording track 26 is in a temporary state and the management table 20 is in an incomplete state. The recording track 27 is one of the vacant areas.
Now, if the time when a program reservation procedure is completed and the time when recording of a reserved program starts are the same, or, if the time when a program reservation procedure is completed is later than the time when recording of the reserved program starts, or when recording of a program is started directly without a program reservation procedure, such recording will be referred to as �instantaneous recording�.
