Embodiment Construction

[0138] Various embodiments according to the invention will be described hereinafter with reference to the accompanying drawings. In general, according to one embodiment of the invention, a write-once type information storage medium comprising: a substrate formed in a disk shape; a recording layer which is formed on the substrate in a concentric manner, and in which information (data) is recorded; and a BCA area which is formed on the substrate in a concentric manner, and in which control data is recorded, wherein an innermost peripheral diameter value of the recording layer is greater than an innermost peripheral diameter value of the BCA area.

[0139] According to an embodiment, FIG. 115 shows an example of a write-once type information storage medium to which the embodiment of the invention is applied. FIG. 116 shows the steps of manufacturing the write-once type information storage medium shown in FIG. 115. FIGS. 117A to 117C show light absorbance characteristics of an organic dye...

Abstract

An embodiment of the invention, to provide a recording method and a storage medium for BCA data with high reliability for a storage medium and a method for reproducing BCA data from the storage medium, and an information recording apparatus and an information reproducing apparatus. In a conventional optical disk, low reliability data is recorded in a data area of BCA. Thus, the thickness of a film material for use in a recording layer oriented to BCA data or close to the inner periphery of the storage medium in the vicinity thereof is formed in uniform thickness by using a substrate of the storage medium, the substrate being formed by being suctioned by means of adsorbing mechanisms formed in an arc shape so as to integrated two of the adsorbing mechanisms to be adjacent to each other.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2005-222036, filed Jul. 29, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND [0002] 1. Field [0003] One embodiment of the invention relates to an information storage medium, such as an optical disk, for storing information, and information reproducing method or an information recording method as well as a storage medium manufacturing apparatus. [0004] 2. Description of the Related Art [0005] In an optical disk such as a digital versatile disk (DVD), a burst cutting area (BCA), a system lead-in area, a connection area, a data lead-in area, and a data area are allocated from its inner periphery side. [0006] Identification information and the like of a DVD specification type are recorded in the burst cutting area. [0007] Japanese Patent No. 3308954, there is a description of a data structure in the burst...
