If the formatted video and recordability/re-disabled the disc; i just formatted or re-initialized to the execution of the disc (10) and transmitted a second or two in the operation (4). Thus, the system controller 10 determines whether the disc 100 is recordable based on the information read from the defect management area 二 access area. If the anti-write flag is set to "丨, or if the access control data 29 13043⁄4^ public information does not allow formatting or writing, the system controller 1 determines that the disc 100 cannot be reinitialized and operates at 1190. In the middle of the host interface 2, the main message is transmitted. Error message. However, if the anti-write flag is not set to 1 and the public information of the access control data allows formatting and writing, the system controller 10 determines the reinitialization. The disc 100 begins to reinitialize the disc 100. At the same time, when access control data is available for functions recognized by the drive system

If there is a value that does not allow the initialization to be initialized and the access control read of the function that is not recognized by the axis system has a value that allows reinitialization, since the value of the access control data regarding the identifiable function can be updated, the identifiable The value of the function's access control data can be returned to the user's reinitialized request = changed to a value that allows reinitialization, a new (four) disc; i 100.

When the film is loaded into the drive system, the drive system detects the position of the block based on the status information of the sub-following control block (including the recorded structure in the defect management area of the disc) and regenerates The effective access control data block. If the Becco is re-initialized, the face access (4) data block has 2 access control and material access control (4) block state f message is included in the disc structure. The access control data block is good (fin is small = 2, and then the access control resource recorded in the access control (four) block is: 疋, the state of the access control data block needs to be changed. The information control material block does not have effective access control woven material and can be used to record access control. During the initialization process, the indicated access control #material block in the disc definition structure has the status information of the access control (four) material block of the I=# material, and the state information of the drive control data block regenerates the access. Control Bay ", -Α Therefore, when re-initializing a disc, it is necessary to update the information in the access control data block so that the information in the access control data block is no longer valid, and the drive system may J to defend the data area. There is a problem with the incorrect information obtained by the block. The entire access control data block in the access control area is included in the access control area except for the control structure block. Block (10) - still needs to be overwritten by some like or h) to physically erase. When ACD_ID, value 00" or "FF", the current access control of the access control data block 32 13045^3⁄4^ is invalid, and the access control data block can be used Record it and access control data. Since the 00h or FFh is recorded in the access control data block when the access control data block is cleared, the ACDJD of the access control data block becomes the value "〇〇,, or "ff,,. In a re-initialization process, the effective access control data block of the access control area on the disc is overwritten by a certain value (such as "0Oh" or "FFh"), and on the disc > Corresponding access control resources included in the meaning structure

The status information of the material block is changed to indicate that the access control data block does not have valid access control data and can be used to record other access control data.

If the access control data block #1, the access control data area, the data block #4 has no recorded data or has invalid f material, the status information of the breeding block #1, access control data block #3 The position of the status information with the access control data block #4 is two: to indicate that the access control data area _, the access control f area = and the access control data block #4 can Used to record access control data. Indicates that the access control data block #2 has a defective bit "〇1, and still works: two data area Lin Chen". Because of access control (four) defects during the birth, access control data block #5 The bit of the status information becomes "01." When an access control data block has a defect in reproduction, the ACDJD of the cough access control data block has a value indicating that the access control data = block can be used for recording. 00h" or "FFh,", and the relevant information of the access control data block is represented by the bit indicating the defective block. In this case, when the ACD_ID of the access control data block is inconsistent with the status information of the access control data block, since the status information is prioritized over the ACD-ID, the access control data block has Defects are not acceptable. However, when the status information is regenerated and the status message cannot be extracted due to an error, an access control data block having "00h" or "FFh" as its ACd_ID is available. In the above arrangement, the status indicated by the ACD-ID of the access control data contained in the access control data block in the access control area on the disc may be related to the disc definition of the 5 recorded on the disc. The status of the corresponding access control data area 36 I3〇45^P, doc block in the structure indicates that the status is inconsistent. In this case, the driver system is designed to be the status information of the access control block of the Weishen. This will be described in detail below. The status of the access control data block can be recorded and recorded from the status of the corresponding access control data block recorded in the disc definition name.

Take the ACD-m of the control block. If the two senses are not mutually exclusive, the drive system mainly relies on the access control data block (4) recorded in the disc structure. When the adj°id of the disc in the defect management area cannot be obtained due to some original area error, the system is based on the recordability in the access control area. There is a defect in the control of the information contained in the control data block. The defect is caused by the defect in the two types of information structures. = If the response is updated, the access control data system Data time; raw CL state information == write, fruit '_:= access control data block Α.

16 is shown as a flow chart of the reinitialization method in another embodiment of the present invention. Referring to Figure u', in operation 161, the old disc (10) is driven by the t system. Then, the system controller H) included in the drive system does not recognize the function controller 1G that the system control $ ig recognizes (such as the access to the disk (10)). Defect management area information and operational information. Next, in the woodwork 1620, the system controller 1 receives a reinitialization command from the host 3 through the host interface. In operation 1630, the system controller 1 controls the read/write unit 2 to read: the information in the defect management area and the access control area (contained in the import = illusion of the disc 1 (8) and to carry the information. For example, recorded in a defect

The poor news in the second area can be an anti-write mark, recorded in the access control area, and information about the recordability or formatability contained in the public information of the access control data. σ In operation 1640, the system controller 10 determines whether information read from the defect management area and the access control area is allowed to be reinitialized. For example, if the anti-write mark read from the defect management area has the value "丨,", writing to the disc is prohibited and re-initialization cannot be performed. The public information of the access control data recorded in the access control area includes the disc. Formatability information and recordability/renewability information for the sub-area of the film. If the formatability information is 38 I3〇45^P, the doc recordability/renewability information is not allowed. Formatting the disc 1 or writing to any sub-area of the disc 100 cannot perform re-initialization. Thus, the system controller 10 determines whether the disc 100 is based on information read from the defect management area and the access control area. Writable. If the anti-write flag is set to "1" or a public tribute to access control data, formatting or writing is not allowed, in operation 1680 the system controller 10 determines that the disc 100 cannot be reinitialized and passes through the host. The interface 2 transmits an error message to the host 3. However, if the anti-write flag is not set to "^, and the public information of the access control data allows formatting and writing, the system control 10 determines to re-initialize the disc 1" And start re-initializing 100. When the access control data about the function recognizable by the drive system has a value that does not allow re-initialization, and the access control data about the function that the drive system does not recognize has a value that allows re-initialization. Since the value of the access control data regarding the identifiable function can be updated, the value of the access control data regarding the identifiable function can be changed to a value allowing re-initialization in response to the user's re-initialization request, and then It is determined that the disc 100 is reinitialized. If reinitialization is permitted, in operation 1650, the system controller 10 allocates a spare area in the data area of the disc 100 to determine the size of the spare area, and assigns a user profile area in the data area to record the user profile to determine the user. The beginning and end of the data area. In operation 1660, the system controller 10 controls the read/write unit 2 to clear the access control area contained in the lead-in area of the disc 1 and update the status information of the access control data. Details 39 I3〇45^P, doc In detail, when the access control area is cleared, the system controller ^ controls the access control value pipe or alarm when the data block is defective, or saves each other Acd"d is changed to "_,, or "FFh," to indicate that the block is the side. In addition, as shown in Fig. 14a_15 == 二 Θ Θ 10 update the status of the control data block changed by the access control device. In the 1670, the system controller 1M reads and writes the defect management area contained in the lead-in area of the disc 100, and controls the reading and writing unit 2 and the servo H5G to record the initial in the defect management area. The defect list and the judgment of the poor news (such as the disc definition structure of the district allocation information period household data area and the updated status information of the access controller material. Although it has been described that the defect tube (4) is initialized after being cleared: In the defect management area, in fact, since the disc cut is a rewritable type, the initialization information recorded in the defect management area is updated. Although not shown in the figure b, the management record is The file system information in the predetermined part of the user data area should be cleared in the data in the user data area. The default access control data (default ACD) will be described below. The access control data can be supported according to whether the drive system supports the The access control (such as whether the drive system can recognize the corresponding function of the access control data) is divided into identifiable access control data and unrecognized access metrics. The control data includes preset access control data. All drive systems that support access control data must support the default access control I3045J63pif.d. Such preset access control data can be initialized on the disc. Or re-initialization period is recorded in the access control area, and can be effectively used. Compared with the access control data of the predetermined function (such as anti-write or regenerative protection), the preset access control data includes information when initializing or re-initializing The storage device is used to access the initialization information of the information storage medium. Figure 7 shows a schematic diagram of the structure of the preset access control data of the present invention. The tea photo map, the preset access control data is It is recorded in the access control area - part of the towel. The default access control (4) has a preset attribute and the structure of the ordinary access (4) data (4), 1700 includes public information 171 〇 欢 information 172 (). ACD_ID 1711 is included in the public information mG, and is marked as "preset ^ to indicate the default access control data. Other information (such as the deficiencies of the information 1712, the defect management area can be recorded Sex/renewability Π13, spare area recordable river regenerative information 1714 and user data area recordability/renewability information 1715) is set to 〇 to allow for shading ° sub-area on the disc The free use of public information mG is similar to the public information of the access control data with the predetermined function in the disk. ..., the specific information 1720 can be recorded in the initialization or re-starting process according to the wishes of the user or the driver. Specific information 172. It is two specific access control data with specific functions: Erfan has a reservation about Wei, such as anti-writing or regenerative. It includes drive ID and record period. Drive 1 = supply, eight records曰, provided from the host. When the recording period and the drive: are included in the preset access control (4) specific information (4) ^ I3 〇 45 ^ P, doc, it is easy to know when the disc is initialized by what drive system. However, depending on the user or the drive system, other types of information may be included in the specific information. Figure 18 is a flow chart showing the steps of an initialization method of a rewritable recording medium in an embodiment of the present invention. Referring to Figure 18, in operation 1810, an empty disc is loaded into the drive system. In operation 182(), the drive system receives an initialization command from the host based on the user's request to initialize the disc. In operation 1830, the drive system returns an initialization command to record the preset access control data in the access control area of the disc. The record of the preset access control data can be automatically executed by the system controller included in the drive system, or can be executed by the host to respond to the write command to set the record information of the preset access control data. Or you can combine these two methods. Preferably, all of the recordability/renewability information contained in the public information of the preset access control data is set to zero to indicate that the disc is recordable/reproducible. The specific information contained in the preset access control data can be set to an appropriate value according to the wishes of the user or the drive system. In operation 1840, in the defect management process, a spare area is allocated in the data area of the disc to replace the defective block. In operation 185, the start bit address and the end address of the user data area are determined in the data area. In operation 1860, the initial defect list and the disc definition structure including the spare area allocation information, the user g area size, and the access control data after the preset access control data are recorded are recorded on the disc. The defect management area of the slice. Since only the preset access control data is recorded in the access control (4), the status information may include status information and a table indicating that the corresponding access control data block of the preset storage 42 丨 if.doc has the data block. : two-be = sub-control data block "Available, access, (4) other access control in operation 1870 Φ block status information. φ,...., respond to write commands from the host to the user (4) Zhong Lu’s official records will be recorded in the user’s second project.

The step of reinitialization method is to record the media ιηπ^# ..., , and Fig. 19, in #1910, the sales disc 100 is loaded into the drive system. In operation 192, the system controller 10 included in A is re-initialized by the host interface.

Buy in the middle

^ If it is determined that the poor communication does not allow reinitialization, in operation, the QSn system controller 10 is directed to the host 3 through the host interface 2, . Strictly, if it is determined that the information is allowed to be re-initialized, the second = to: specify the user data area of the spare area - the bedding area in the fixed_area to determine the start and end of the user data area = the household is in the 1960, The system controller 1 〇 controls to read the access system included in the lead-in area of the disc 100,: early 702 > monthly access control data or control data with a new preset stock == 43 \ if.doc . Here, in the recording of the preset access control, the first control may clear or may not clear all access control data blocks in the access # system. Since the preset access control resource is initialized _ _, and the value contained in the preset face control (four) material is appropriately set according to the user's intention when the disk 1GG is included, the preset record recorded before the second time The control f material can be overwritten by a value that is set according to the user's wishes for reinitialization (10). All recordability/renewability information contained in the public information of the preset T control data is preferably set to 〇 to indicate that (8) is recordable/reproducible =. In addition, the specific information contained in the preset access controller can be set to an appropriate value according to the wishes of the user or the drive system. First, in operation 1970, the system controller 1 controls the read/write unit 2 to clear the defect management area in the v input area, and controls the read/write unit 2 and the server %, and records the initial defect list and the spare reserve allocation in the defect management area. The size definition information of the user data area and the disc definition structure of the updated bear control information of the access control data. In operation 1990, the system controller 10 reinitializes the file system information in response to the write command from the host 3, wherein the file system information is recorded in the user~data area for reinitialization for managing the record in the user data area. Information on the information. FIG. 20 is a schematic diagram showing the structure of writing a recording medium =0 in one embodiment of the present invention.
