摘要:
An information recording medium includes at least a disc-shaped first recording layer having a first recording track formed for recording record information and a disc-shaped second recording layer having a second recording track formed for recording the record information in the same recording direction as the first recording track of the first recording layer. A second place serving as a reference of a pre-format address for indicating the start position of the data area in the second recording track (position of a circle of address 30000h in the radius direction in the L1 layer) is located at an outer side as compared to a first position serving as the pre-format address for indicating the start position of the data area in the first recording track (position of a circle of address 30000h in the radius direction in the L0 layer) at least by a predetermined first offset amount.

摘要:
Information recording is conducted in the form of the simple format. When the simple format is indicated, the recording control data is not recorded in a lead-in area LIA, and after the information to be recorded is recorded in a data recording area DRA, the recording control data is recorded in a recording manager area RMA and a lead-out area LOA, in the data recording area DRA, recording manager area RMA, lead-in area LIA, and lead-out area LOA, which are predetermined according to the standard format. Further, when the finalizing processing is indicated, by recording again the recording control data according to the standard format to the information recording medium in which the information recording is conducted according to the simple format, the information recording medium which can be applied to the common information recording and reproducing apparatus, is easily realized.

摘要:
According to the present invention, there is provided an information recording apparatus in which, even when the apparatus is an information recording apparatus which cannot previously determine that a recording signal with any attribute is inputted, a recording signal conformable to DVD video standards which is recorded in an available optical disc can be prevented from being illegally copied. The information recording apparatus includes a CPU for detecting whether a recording signal to be inputted from the outside is a specific recording signal having characteristics as a recording signal recorded in an available optical disc and, when it is detected that the recording signal is the specific recording signal, inhibiting the recording signal from being recorded in an optical disc.

According to the present invention, there is provided an information recording apparatus in which, even when it cannot previously determine that a recording signal with any attribute is inputted, recording information conformable to DVD video standards etc. which is recorded in an available optical disc can be prevented from being illegally copied with a simple and low-cost configuration. According to this, there is provided an information recording method including the processes of: detecting whether a recording signal to be inputted from the outside is a recording signal conformable to DVD video standards only for playback; detecting whether the recording signal includes an inhibition flag indicating that the recording signal is inhibited from being recorded as an analog signal; and, when it is detected that the recording signal conforms to the DVD video standards and that the recording signal includes the inhibition flag, inhibiting the signal from being recorded.
