Description of the invention: [Technical field to which the invention belongs] The present invention relates to a record carrier, a drive device and a method for reading or writing a record carrier like an optical disc. In particular, the present invention relates to an improved defect management scheme. [Previous Technology] Defect management is a major aspect of current storage solutions. Even if the media used is not flawless, some hosts, such as a PC running Windows, require certain storage devices to expose a flawless address space on the interface. The most common solution to this problem is: If a defect is detected, the storage device remaps the logical address of that location to another physical location. In the case of a disc, the other physical location may be located inside the lead-in area. The area reserved as an alternative physical address is called the spare area. Sometimes remapping interferes with the real-time aspect of the stored file. This is the case, for example, if a real-time file is being re-mapped due to a defect in the original magnetic zone, and it is necessary to fetch a block from an entity remotely located on the media. One way to deal with this problem is called slip. Slip is often used in the following ways. After = is initialized and verified, a list of major flaws will be generated. The logical address mapping of the physical address has now been adjusted, the defect location has been crossed, and the address has slipped to the spare area. If there are no new flaws, the instant application works well. Once the disc is used consistently, the address mapping will be fixed. A recording medium with a spare area for defect management is from document 97892.doc 200527386 EP0997905. This file description includes

Machio drives are like a memory card. However, in the case of removable discs such as Qing 0, new defects must occur during the lifetime. One way to deal with it is to make the host allow the application to close the defect and remap it ^ ^ ^ 耵 Let the application be controlled by the defect disposal ', for example, by crossing the defect magnetic field and writing the hope in the defect magnetic field Bottom—Magnetic zone. The latter line—species, instant sliding ρ). Removable disc systems such as the SFFO system impose on optical storage — new restrictions. The disadvantage of the existing defect management scheme is the fact that it ignores power consumption issues. However, for the _〇 system, it is important to reduce power consumption 'because it often cuts off the main power and operates in a mobile environment. If the spare area is-away from the entity, it will take too much power to retrieve the remapping data 'because each encounter-a defect will require a jump, and the laser must be turned on during the jump (the most power consuming component) One). In the case of the sff〇 system, 'traditional sliding ⑽p) is not an option, because during use, SFFO will generate flaws in real time, and sliding ⑷⑻ is not always an option—because some applications have no concept on this, but it remains Must be able to fake 97892.doc 200527386 Γ address "w ° 'real-time sliding ⑽p), the other-the shortcoming is. · Pass * If a defect suddenly appears in an area that has been written, you must rewrite a file and / Or a larger part of the fragment. The obvious solution is to cache the entire field in the driver. However, even if the spare area is not actually used or is only partially used, the extra memory is still very long. And more and more memory will require additional power. Dan Xiong / ,, Zhuan Xiu In the existing scheme, the preparation of the light domain is usually located in a typical area. A # rate, "... retrieve and remap Data will consume a lot of functions (when encountered—when it is exhausted, it must jump from the position of the data to the standby & domain and return. [Summary of the invention] An object of the present invention is to make contact. The US provides a method for The feasibility of the proposed disease management plan is the province's special warfare method and driving clothes. This purpose is achieved by _write 21_ 中 、 户 二 's as claimed in claim 1 in item 10 -Record carrier, such as the requesting recorder 1 ", / as stated in a claim 5 '1 / item 13 as claimed in item 12-drive device to achieve. A new form of flaws is prepared The Θ 竑 optimization domain of the position and remapping magnetic field is included in the read segment. M # is taken. By reducing the work m by using the spare area, there will be no additional search burden, because of the 彳, and it results in excellent real-time characteristics. After enclosing the film γ, for example, the laser can read 1 to take the film & — to save power from Ding M. At the same time, the flaw can be implemented by driving L ^ 1 thinking, using spears The formula does not need to know ^ {ear # new mapping, but it can still meet the real-time J f to read the spare 97892.doc 200527386 area if necessary. The program area will contain a further segment, which contains a further spare located at a boundary of the further segment. Area, where the segment is located next to each other, and the segment is spare The position of the domain is adjacent to the further spare area of the further fragment. In particular, the spare area and the further spare area are combined into a combined spare area of the remapping of the fragment and the further fragment. Positioning a spare area on two pairs of ## again to minimize the total number of spare areas. This results in a reduced number of spare areas because one area is available for two adjacent segments. Furthermore, a reserved spare area will be provided, The reserved spare area is located adjacent to the program area. In case no space is left in each of the associated or exclusive spare areas, additional space can be provided for remapping. The blocks in the segment can be added with a logical address Addressing, where each block contains a -only-address. Then, since there is a spare area that is not logically addressable, the continuous fragment is larger than the logical fragment. This provides a well-defined storage device interface. Meaning: A defect management table is provided on the record carrier. The table contains a defective block ^ logical address only and contains a link to a physical magnetic field associated with the defective block. According to the information derived from the defect management table, it can be known whether the next segment contains a remapping data, so the remapping data can be obtained from the same scan item. Further advantageous amendments will be defined in the dependent claims. [Embodiment] In different drawings, corresponding elements have the same reference numerals and symbols. 97892.doc 200527386 A private example will now be explained, in which it will be revealed: like: a better-equipped m-camera other than a PB drive, and a first-class heritage owner. In this context, the term I, Legacy 0 h earlier than current technology, gey) means 格式 σ flat mouth and such formats, materials or devices inherited by technology. Legacy devices are not well equipped to handle flaws. It can be assumed to be a flawless solid state memory. FIG. 1 shows the adjustment to be suitable for, for example, a close room format = device: 〇. Therefore, the driving device can replace solid-state memory. For the 4 functions, a standard interface with a corresponding connection terminal 32 will be provided. The surface connector 2 () can be arranged to be used on the writer removable drive device 30 from the internal disc 10. An internal broadcast system maps an external broadcast system used by the access drive device 30, and maps from the ㈣ file system to the external file system when fetching from the disc. The PB logical format provides the opportunity to spread spare areas across the disc. PB series = 6 fetch / write cycles are based on segments to reduce power consumption. A segment is a group correction code (scan correction code) block that is read / written by m scans. Generally, the buffer management of Ezhi meets this kind of basis: Duan Liji fetches all the data required for the special task or period from the allocation in the segment, and then the optical unit of the drive device 30 can be closed after the segment is read: Laser to save power. The point is that it has units that can be selected in one scan. If the application runs out of data in the buffer, it reads another segment. Obviously, the defect management is still performed by the driving device 30. The running application only reads the segment, and if necessary, the drive device 30 will take the item to a spare area. The physical fragment is thus larger than the logical fragment, that is, the physical 97892.doc 200527386 f-segment size = logical fragment size + spare area size. In other words, the storage benefit or drive = Yujia 30 is still a bit engine, and there is a definition between it and the host ^ 1 spare area cannot be accessed through the interface unit 20, such as address 0 according to a better specific f, X y tm _ — Through the yoke example; 丨 early 20 yuan provides a defect management function or early 22 'which is adjusted to use-the first and / or last set of sectors or ECC blocks of the segment as the user in the segment A spare area for data. Beans facilitate a power-optimized blemish management solution that provides excellent instant characteristics. If during the writing of a special segment, the defect management unit 22㈣ to -㈣ £ block 'it will control the interface unit 20 in order to preferentially remap the block to one of the reserved areas located at the beginning or end of the segment. Block. The data is read one segment at a time during the "first job" period. If you know from reading a defect management table provided on disc 10-the segment contains one or more remapped areas in the spare area of the segment Blocks, then these remapped blocks are read with the same scan, resulting in little or no additional power use or time donation. '| ≫ u only] Lost if the acquired segment does not include a remapped area Block, the spare area is not read to ensure that the scheme does not impose additional burdens. It is based on the following observations: a new way of governing the use of the physical address space of the entity facilitates a new form of defect management, which has An optimized position of the spare area and a __power optimization extraction of the remapped magnetic area. One disadvantage of the traditional system with many relatively small spare areas is that no defects occur, 'still need to skip' In order to skip the spare area after each segment. This is not true for the proposed system. During normal operation or at least in low power mode, the application will open the drive% and read a 97892.doc -10- 200527386 clips, and then sometimes shut down the drive 30. It does not want to read a series of clips at a time, so no extra jumps occur. By including the spare area in the read clips, there will be no additional search burden, reducing power consumption At the same time, Blemish Management can be implemented by this driver, that is, the application does not need to know the remapping, but still meets the real-time guarantee. At the same time, it reads the spare area when necessary. Please note that in the PB system, the fragment It is the layer between the file system and the bit engine used to manage the physical space of dialogue or segmentation components. Not all fragments are in logical space, and not all physical sectors are part of a special fragment. If the file system will take over For defect management, it is possible to decentralize the same spare area, and it is the best. Therefore, most of the above suggestions are still valid. However, better, the defect management is performed by the driving device 30 (for example, by the defect management component 22). Implementation. Figures 2a to 2d show the unintentional representation of the allocation of an information area and a spare area provided by the disc 10.

The first preferred embodiment described in Figure 2b In the configuration, the spare area SA is formed by the last £ (: [block of each segment constituting a plurality of Ecc blocks, and will have a size of, for example, approximately 5 MB. Furthermore, as described in FIG. 2c In the configuration of the second preferred embodiment, a spare area SA is provided between every two segments of 97892.doc 200527386, which is composed of the last block of the first segment and the first block of the last segment. Finally, the advantage of the configuration of the third preferred embodiment described in FIG. 2d is that it minimizes the number of spare areas SA. In the third preferred embodiment, the last block of the segment Fn and the first block of the segment Fn + 1 form a common spare area SA. However, no spare area is provided between the segments + 丨 and ++. . This means that two segments, grouped or paired, share a spare area SA at the edge where they are shared. For example, for a 1024MB disc, which has 5 segments and a 5% reserve for defect remapping, it will require 100 spare areas sa each with 16 ECC blocks. Figures 3a and 3b show a schematic representation of two alternatives or examples of the first spare area 第三 in a third preferred embodiment, wherein each of them is shown in Figure 3a and Figure 'Reserve areas SA2 to SA (1 / 2n + 1) or spare areas ㈤ to Μ㈣) are shared by respective adjacent segments containing user data UD. Up arrow dragon represents the address of the logical address space. "Figure 3a depicts a situation where the user leaves the reserved space in the user's mind and reserves extra space in the first spare area SA1 for defect remapping. Figure 3b depicts a situation other than the above, where no additional space is provided. / Next, let ’s talk about root selection. The proposed defect management solution requires a special mode of operation, according to the first description of the third preferred embodiment shown in FIG. 3a. The defect management table detailing which blocks are remapped is stored in the disc specified defect management area_). Install on disc 10, read, and then cache. During the ordering period 97892.doc -12- 200527386 Figure 4 shows a schematic flow of a method for writing data on the disc 10. The picture starts at step 01 and writes a fragment. At step 102, if the system detects a defective block during the writing of the special slave, the system will remap the block. Then in step 103, it is checked whether the associated spare area of the current segment is filled. If not, the block is remapped to a block in a spare area shared by an adjacent segment paired with the target segment ( Step 105). It will be at the beginning or end of the segment. 2. Ruguo detects in step 103 that there is no space left in the associated spare area in the same segment, and then checks in step 104 whether an adjacent segment of the same fragment pair & is left in the spare area. Any free space. If yes, remapping is performed on the adjacent spare area in the adjacent segment (step 107). If this adjacent spare area is also full, an auxiliary remapping procedure is started in step 106, where an immediate optimized remapping solution using the nearest spare area with space can be used or the first spare area can be used长期 A long-term power optimization solution among surplus workshops. The former minimizes the search time, while the latter reserves space for future remapping within the same segment. At step 1G8, the current segment is written with _scan. Finally, in step H) 9, it is checked whether or not a new segment is written. If yes, skip to step 1 01. Otherwise, the writing procedure ends. FIG. 5 shows a schematic diagram of a method for reading data from the disc 10. During normal operation, the data is read-segments. First, read the ㈣ management table at ㈣201. If removed from the job management vote at step 202-the segment contains one or more remapped blocks, then if at step 203 it is decided to remap the region, it is assumed that the previous block is located in the same or paired segment as a spare 97892.doc -13- 200527386 Zone or Zhongbei uses the same scan to read the remapped data and the user profile in the clip together (step 204). If it is decided in step 203 to remap the block bits: the ground floor is not in the same segment, then a search must be performed in step to manipulate the remapped block. Then, in step S4, the segment 读取 is read without including its associated spare area. Finally, in step 207, it is checked whether the item is fetched-new segment. If yes, the program skips training. Otherwise, the reading process ends. 'In short' proposes a lexical scheme for an optical record carrier such as -SFF0 or PB discs in a mobile environment. The record carrier contains data segments, each segment containing one or more blocks. As exemplified, a fragment may have a size of about 2, 5, or 10 mm. Its maximum size is determined by the minimum size of the hard buffer H that drives it. It will be read and written by the device in a scan. The spare area will appear on disc two and the defective block will be remapped to a spare area. These spare areas are located at the edges or boundaries of the clip. The result is a complete optimization to reduce power consumption without compromising defect management. Combining a spare area with a segment has the advantage of no additional search burden and therefore saves power. Defect management is implemented with a driver, so the app doesn't know about remapping. It can be 'instantaneously guaranteed' because reading-remapping blocks will not cause a jump in a disc-type area. The spare area is read only when needed. It must be further noted that when the term " include " is used in this specification (including the request), it is used to describe the existence of the stated feature, whole, step or component, but does not exclude one or more additional features , Whole, step, component or group thereof. At the same time, it must be noted that the word “97892.doc -14-200527386” before a component in a claim does not exclude the reference of multiple such components. The symbol does not limit the scope of the request. Furthermore, any software and software can be implemented, and if "quote" can be expressed in hardware at the same time. Furthermore, the present invention often: can be added to the same hardware item in the present application & fortunately, the characteristics or combination of characteristics. This case is not limited to the re-examination of the above specific defective data part, but can be used in the record carrier system based on the remapping operation of the "knife".
