In detail, the disc definition structure 41 includes the spare area size information 411 and the user data area start and end bit address information 412 'as the information recorded on the disc during initialization or re-initialization. When the disc is initialized or re-initialized, the drive system allocates a spare area in the data area, determines a user data area 122 in which user data is recorded in the data area, and defines a structure 41 for the disc to record the related spare area and user data area. 19 20053, 14 ^ 1 122. The defect list 420 contains information about defects occurring in the user profile area 122. For example, the defect list 42 includes the address of a defective block occurring in the user profile area, the address of a spare block to replace the defective block, and the status information of the defect. FIG. 5 is a schematic diagram showing a detailed structure of the access control area 113 in FIG. Referring to FIG. 5, the access control area 113 includes access control data # 151〇, access control data # 2 520, and access control data # 3 53. The access control area 113 is an area for recording public information, where the public information is used to access an existing standard or a new standard disc. In other words, the access control area 113 stores a public eight-negative Λ table, and the public information table is generally applied to all existing functions and new standards. Although not required in all respects, the access control data constitutes a common information sheet about each function. For example, the access control data # 1 510 constitutes a public information sheet related to "Function 丨", the access control data # 2 520 constitutes a public information sheet related to "Function 2", and the access control information 530 = becomes related to "Function 3" "Public info sheet. A drive system may recognize function 1 but not function 2 and function 3. The access control data may also contain specific information that can only be identified by a drive system that is capable of associating a function with the access control data.
