The order in the lead-in area is the first field ID (Field ID 1), the second field ID (Field ID 2) 'the third field ID (Field ID 3), and the fourth Field ID (Field ID 4) and Fifth Field ID (Field Π) 5) and so on. The definitions of the five field IDs are as follows:

Field ID 1: disc application code and disc characteristic data

Field ID 2: Best writing power recommendation code and writing method strategy coding data

Field ID 3: The first record area of the maker identification code

Field ID 4: The second record area of the maker identification code

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

V. Description of the Invention (A) In the production of high-speed readable and writable digital audio and video optical disc players (DVD_R / D criminal-Rw), in order to promote the compatibility between the disc drive and the disc, the high-speed disc must be Information such as writing power, erasing power, and reference speed are pre-engraved on the land of the disc. That ’s why, in the future, Land Pre-pits of discs that can be read and write digital video disc players (DVD-R / DVD-RW) will require two to four areas to be identified. Code (FieId ID) to store this information. Therefore, in order to prevent the current disc drive from being unable to process readable and writable digital audio-visual disc (DVD-R / DVD-RW) discs containing more than five Field IDs, and to make the disc drive easy to know The total number of field categories in the disc to save the time for the optical disc drive to search for the field information, so the invention of the patent case is triggered, which is the motivation of the present invention. (3) Brief description of the invention: The present invention mainly counts the number of categories of the field identification code (Fie 1 d ID) with a counter. Therefore, in the future, it will be a rewritable audiovisual disc player (DVD-R / DVD.) When the number of Land Pre-pit fields needs to be increased, the disc player can know the total number of field categories from the count of the counter, and know how many fields need to be explained ( Field) (Please read the notes on the back before filling this page)

In view of the use of the counter concept proposed in the present invention, the counter is applied to the data format of Land Pre-pit of a rewritable audio-visual disc player (DVD-R / DVD-RW) using the counter. To count the number of categories of the Field ID, so when a rewritable audiovisual disc player (DVD-R / DVD-RW) needs to expand the Field ID in the future, you only need to count this It is engraved on the disc, and the disc player can know the number of field categories stored in the Land Pre-Pit by counting the number of fields.

Explanation of the invention () FIC = b3 x23 + b2 x22 + b {x2l + b〇x2 ° +500 (2) The above formula (2) assumes that the FieId ID Counter is named FIC , And its maximum bit is h and its minimum bit is b0. This field ID counter (値) is obtained by the operation result of the above equation (2). 2_2 The present invention is based on the principles of a writable readable and writable disc player (DVD-R / DVD-RW) disc embodiment. The following is to make the implementation of the present invention more concise. An example is used for illustration. First, the first case is assuming that the field ID counter's code is 0000b, so the FIC equation of formula (2) is brought into the solution, and the FIC 値 is 5, which means that it is being imported. (Lead-in) area has a total of five field (Fi led) category information. Therefore, when the disc is interpreted, the largest field ID number is 5 which can be obtained from the field ID counter of the first field ID (Field ID 1). In addition, Figure 11 shows that the disc of the present invention contains five field identification codes (Field ID 1) in the first field identification code (Field ID 1) of the pre-pit data (Lead-in) in the lead-in area.

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.

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 !

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.
