Information recording medium, and recording method for information recording medium

Abstract

When there is a PCA of the second recording layer at a position opposite to the PCA of the first recording layer, as a result of the stepwise change of the recording laser power to the PCA of the first recording layer, the PCA reaching the second recording layer The amount of light varies, making it difficult to determine the optimum recording laser power. The PCA area (d1) of the first layer recording layer (L0) and the PCA area (e1) of the second layer recording layer (L1) are configured to offset each other in the radial direction of the optical disc so that they do not overlap in the lamination direction, and will be aligned with The PCA area (e1) of the second recording layer (L1) overlaps in the stacking direction, and the area on both sides of the PCA area (e1) is at least larger than the eccentricity, and is configured as a physical format area (d4), and then approximately The respective data areas (a12 and b12) of the first recording layer (L0) and the second recording layer (L1) are arranged facing each other. Before recording the test signal to the PCA area (e1), the control data is recorded to the physical format area (d4).

Description

[0001] This application is a divisional application of the application filed on April 11, 2005 with the application number 200510065039.2 and the title of the invention is "Information Recording Medium and Recording Method for Information Recording Medium". technical field [0002] The present invention relates to an information recording medium and a recording method of the information recording medium, and in particular to a single-sided double-layer Digital Versatile Disk (DVD: Digital Versatile Disk) having multiple discs capable of optically recording and reproducing information signals from one side. An information recording medium with one recording layer and a recording method for the information recording medium. Background technique [0003] In recent years, the development of a single-sided dual-layer DVD having two recording layers capable of optically recording and reproducing information signals from one side has been actively developed, and various recording an...

Problems solved by technology

[0016] In this way, compared to the end of the general test recording at about one track, the excess number of tracks is wasted, and the limited PCA area is used in vain, and the format cannot be actually formatted.
