example 1

[0229] exist Figure 41A and 41B In the recording sequence described in , the width of the data area is first fixed by formatting, and the recording of the predetermined guard band of layer 0, the recording of the format information band of layer 0, the recording of the management band of layer 0, etc. are performed. Subsequently, data is recorded to the data area. Data recording starts from the innermost circumference of layer 0. When the recording of layer 0 is completed, the laser beam is moved to layer 1 to record data from the outer circumference to the inner circumference of layer 1 . When data does not reach the innermost circumference of layer 1, the optical disc device automatically records dummy data such as a terminator to fill all data areas of layer 0 and layer 1 with recording data. Recording is further performed on the guard zone of layer 1 to complete the recording on the disc. Figure 41A and 41B corresponds to Figure 39 upper and lower parts.

example 2

[0231] exist Figure 42A and 42B In the recording sequence shown in , a method of additionally recording data sequentially in a state where only one open R zone exists is used. Data recording starts at the inner circumference of layer 0. When recording of layer 0 is completed, recording is started from the outermost circumference of layer 1 . This order is the recording order shown in Figs. 34A to 34F (border structure).

example 3

[0233] exist Figure 43A and 43B In the recording sequence shown in , a method of additionally recording data in a state where multiple open R zones exist is used. In this case, if Figure 43A As shown, there is an open R band on layer 0. When layer 0 has an unrecorded area, the overlapping portion of layer 1 is a recording prohibited area. like Figure 43B As shown, when recording is performed in the unrecorded area of ​​layer 0, the recording prohibition of layer 1 is canceled.

[0234] (method of recording prohibition)

[0235] Figure 44A and 44B The relationship between the open R zone of layer 0 and the extent of the recordable area is shown. exist Figure 44A In the state shown in , the inner and outer circumferential guard bands of layer 0 are recorded, and data is recorded onto layer 0. However, layer 0 has two open R zones, and data is not recorded into the open R zones. In this case, as Figure 44A and 44B As shown, the recordable range to be used as th...

Abstract

According to one embodiment, a single-sided multilayered information recording medium having recording layers, wherein an emboss management zone, an inner recordable management zone, a data area, and an outer recordable management zone are sequentially arranged from an inner side of each of the recording layers, and a burst-cutting area is arranged inward of the emboss management zone in any one of the recording layers.

Description

technical field [0001] An embodiment of the present invention relates to an information recording medium having a plurality of recording layers formed on one side, an information recording apparatus using the information recording medium, and an information recording method. Background technique [0002] As a recording medium on which a large amount of information such as video signals can be recorded, DVD (Digital Versatile Disc) is very popular. A movie having a length of about two hours is recorded on a DVD, and the information is reproduced by a reproducing device, making it possible to freely watch the movie at home. In recent years, digitization of television broadcasting has been proposed, and practical realization of a high-definition television system called a high-definition television (HDTV) system is planned. Therefore, a next-generation DVD standard is proposed that narrows the beam spot of the DVD by shortening the laser beam wavelength or increasing the numer...
