Description of the Invention (ID) (Field ID 5) and so on, and then arrange them in the Lead-in area repeatedly, that is, the configuration definition shown in Figure 6. The figure 6 shows the definition of the encoding configuration of the pre-pit disc information in the lead-in area of the existing discs. The purpose of repeating the sixth figure from the first field ID (Field ID 1) to the fifth field ID (Field ID 5) in the lead-in area is to solve the problem When some ECC Block signals in the -in area cannot be reproduced, since each Field ID is copied in the Lead-m area, it will not be reproduced. Because the error correction code block (ECC Block) cannot be reproduced, the reading of the identification code content in various fields is affected. From the above definition, it can be known that in the field of encoding of the disc information of the current read-write digital video optical disc drive (DVD-R / DVD-RW), each field (Fi e 1 d) has been defined for its purpose ' Therefore, the encoding of the plane pre-engraved data (Land Pr e-pi t) did not take into account that the field identification code (Fie 1 d ID) must be retained and used for future expansion in order to store more disc characteristics Space for information; so if more disc information needs to be engraved on the disc in the future, the currently defined encoding format will not be applicable. Furthermore, for the future, this paper size will apply the Chinese National Standard (CNS) A4 specification (210X 297 mm) (please read the precautions on the back before filling out this page) Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs

An operation is performed through the above equation, where bn = 0 or 1. To further make the above calculation formula of the counter clearer, an example will be given as an example. Assume that the counter consists of 8 bits. Yuan ( BU) encoding, and assuming that the 8-bit data is 00000010b, then η 値 should be 7 at this time, which is why the above-mentioned FC equation can be taken into account, and FC 値 can be solved by 2. The number of counters 値 is 2. For the coding principle of the present invention, when a counter is used to count the number of categories of the field ID in the lead-in area, it is necessary to consider a read-write audio-visual disc player (DVD-R / DVD-RW) three main implementation strategies: (1) Provide easy access to counter information; (2) Reasonable field (FieId) expansion number and other best implementation methods; (3) Have estimated expansion fields (FieId) the best implementation method such as the capacity of the number.

Description of the invention (>?) When adding the counting function of the counter, it is better to arrange in the existing reserved space. In this way, it can be compatible with the current DVD-R v2.0 and DVD-RW νθ.9 disc specifications. It also provides a plan for a new message, as shown in Figure 20. The twentieth figure is the first pre-pit of the data in the lead-in area of a read-write digital video optical disc drive (DVD-R / DVD-RW) according to the present invention. The definition of the coding configuration of the five Field ID 5 messages is mainly to define the address of 1100b of the serial number 12 as the Expanded Field ID number (Expanded Field ID number), which can be further expanded to 255 field categories. FIG. 21 shows the encoding definition of the expanded field ID number (Expanded Field ID Number) message in the fifth field ID (Field ID 5) of the disc of the present invention, so that the present invention can have an estimate The ability to expand the number of domains (Fie Id). Regarding the application of the coding principle of the Expanded Field ID Number message (Expanded Field ID Number) described in the fourth part to the actual implementation, it is described as follows: 4.1.

B7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention) The principle is as follows: The number of identifiers for the expansion field ID Number) The encoding principle of the message is mainly divided into: (1) the Expanded Field ID Number is composed of 8-bits encoding; (2) The algorithm of the Expanded Field ID Number is as follows: EFrN = b7x27 + b6x26 + ... + ^ X21 + b〇x2 ° + @ (4) The above formula (4) is based on the assumption that the amplified field identification The name of the expanded field ID number is EFIN ' And the maximum bit is b ?, and the minimum bit is b0. Thus, the counted number of the counter in the amplification field identification code number 値 is calculated by the above equation (4). 4_2 In the present invention The principle principle of the real-world readable and writable digital audio CD (DVD-R / DVD-RW) disc is as follows: In order to make the content of the field identification code number 値 in this embodiment more detailed, we will give one The embodiment is explained. The first example is: first assume that the code of the Expanded Held ID Number 値 (Expanded Held ID Number) is 00000000b 'so it is brought into the equation (4) of EFIN, and the number of EFIN can be solved It is 0, which means there are only five types of collars in the lead (in) (please read the precautions on the back before filling this page). 1 This paper size applies the Chinese National Standard (CNS) A4 specification (2 !

Description of the invention (Xue /) Domain (Filed) category information Therefore, at this time, there is no information of the field ID 6 in the Lead-in Land Pre-pit. See Figure 22, which shows that the disc ID of the present invention contains only the basic five fields in the field ID of the pre-cut data (Pre-pi t) in the lead-in area. The physical configuration and decoding principle of the Field ID message differs from Figure 11 in that it reads the Field ID Counter from the fifth Field ID (Field ID 5). This will further expand the categories of fields. The second example is based on the assumption that the code of the Expanded Field ID Number (Expanded Field ID Number) is 0.0000000lb. Therefore, the equation (4) of EFIN is taken into the operation equation, and EFIN is solved as 5, at this time, it means that in addition to the basic five categories (F 丨 e 丨 d) category data in the introduction (Le ad-i η), there are five categories of category information to be explained. Therefore, when explaining the contents of the disc, the five field identifiers with the expanded field ID number (field ID 5) can be found in the expanded field ID number. The (Field ID) category is imported into the plane pre-engraving data (1 ^ 11 (1? 1 ^ '〇) in the area of ^ (17).
