The defect management method for the write-once recording medium will be described in detail below. The invention introduces a consistency flag (hereinafter referred to as C_flag), which details the information of the TDMS update cycle and the TDMS update cycle in order to determine whether the lack of other management on the information storage medium is irregular due to irregular events during the recording of data. non-continuous.

FIG. 6 is a state diagram illustrating a write-once recording medium performing defect management according to an embodiment of the present invention. Referring to FIG. 6, TDMs describe write-once records, two states of the body: having c — f lag = ”, The TDMS update cycle on% status and C —f iag = ”〇 ,, ^ ㈣ update cycle off status, the value is determined and recorded according to the status of the updated TDMS, | ,, one " write once When the recording media is loaded into the recording media drive and the C — flag is 1, the drive will consider irregular events (such as a power failure that occurs between the usage log and a certain physical work) and such defect management will not be normally performed. Laugh, '2 C flag in' 2 is the status information about the updated TDMS.

As shown in FIG. 4 and FIG. 6, the method for managing write-once recording media defects according to the embodiment of the present invention will be described in detail as follows. First, write once, load it to the recording media drive (job 10), and write once, write Γ to reach state 1 〇 'and state 1 0 〇 indicates that the data has never been recorded with the name C —f lag = On media 4, or once a writer recording media 4 enters the shoulder and the defect management 祜 fMS update cycle is closed, which is the latest updated in ™ is when the data is recorded 镝 3 = 2 functions performed in it. When the second write is not recorded on the write-once recording medium 4, the ",,." The controller 2 will be the first in the main TDMA during the initial period of the recorded medium 4.

200425081 V. Description of the invention (14) In the cluster, C — f lag = 0 and information on defect management using a recording medium drive, C-falg will be recorded in TDDS, as shown in Figure 2 and Figure 3. According to this embodiment, a TDDS with C — f lag = 1 is recorded and the write-once recording medium 4 enters the state 100, so that the TDMS update cycle is opened to correspond to a host instruction or according to a recording / reading job (job 2 0) And the write-once recording medium 4 enters the TDMS update cycle open state. Two cases where the TDMS update cycle is open are as follows: I. The TDMS update cycle is opened by a host instruction. When a write-once recording medium 4 (more specifically, the latest record TDDS) containing the final TDMS with C — f lag = 0 is opened. When loaded into the recording medium drive, the controller 2 receives an instruction from the host (not shown) to open the redundant update cycle. After that, the controller 2 controls the recording / reading unit} to

C_flag = l records the position of TDDS at the next TDMS to the latest TDMS recorded in TDM to indicate the TDMS update cycle open status. In this case, C_: the value of Hag will change but other information (eg wTDFL) will not Change, so 'only TDDS containing C — f 1 ag is recorded in the new cluster. Π Open the TDMs update cycle according to the recording / reading operation. When a new write-once recording medium with C_flag = " 〇 " is loaded into the recording medium drive and data is recorded or read ready Well, the host will send the write / read command to the recording medium drive and the 'body drive will perform the recording / reading operation' on the write-once recording medium 4 'if the TDMS needs to be updated during the recording / reading operation / System will control 5 recording / reading unit 1 with C — f 1 ag = 1 to record the position of rp in a ° TDMS to the latest TDMS recorded in TDMA

! 3552pif-Ptd 200425081 V. Description of the invention (15) TDMS will be updated after one or more write-after verification methods or write a predefined amount of data. At this time, TDMS is updated to include c-fUg = l It is recorded in TDDS. — Σ Similarly, when the cluster is judged to contain defects during the reading of data from the write-once recording medium 4, the defect management of updating the TDMS is also performed. After state 1 10 (where the value of c — f lag is recorded as 1 and the update cycle is open), the record / read job (job 3) is executed and a new TDMS is created and stored in memory In 3, in order to effectively use TDMA, when the host gives an update command, the controller 2 preferably executes the TDMS update by recording only the TDMS in the TDMA (operation 50). The controller 2 includes C_flag = i to TDDS to update TDMS and the TDMS update loops back to state 1 0 0. After the TDMS update cycle is opened to correspond to the instruction to be opened by the host or according to the recording / reading operation ... After the update cycle, the instruction to exit the write-once recording medium 4 from the recording medium drive or close the tdms update cycle * After the ring command is given (job 40) ', the controller 2 controls the recording / reading unit 1 to record with C_f iag = 〇] ^ In 71) the difficulty here, C — flag = 0 indicates The TDMS update cycle is closed. When a TDDS with ^ flag = 〇 is recorded in TDMA, the write-once recording medium 4 enters the tms update cycle closed state 1 3 0. If the host gives a command to close the TDMS update cycle instead of exiting to write to recording medium 4, the TDMS update cycle enters state 13 and returns

200425081 V. Description of the invention (16) In the state 1 0 0, in the state 1 3 0, when the host gives an instruction to exit the write-once a recorded medium 4 ', then the write-once recording medium 4 will be removed from the recording medium drive. Was exited (job 70). In the state 1 3 0 'If the user is given an instruction to write the recording medium 4 once, the controller 2 will control the recording / reading unit to record the data (for example, nff hn) in the blank space of the TDMA. Prevent the recording of data in tdma, such as TDMS containing TDDS, TDFL or SBM. As described above, according to the embodiment of the present invention, C__f 1 ag is recorded in τ d MS, where C_f lag indicates two states of the TDMS update cycle, that is, the TDMS update cycle open state and the TDMS update cycle closed state, Therefore, it is possible to check whether an irregular event (such as a power shortage in the recording medium drive) occurs during the use of the write-once recording medium 4 if a power shortage occurs during the use of the write-once recording medium 4 in the recording medium drive , The value of the C_flag, which indicates that the TDMS update cycle is open, will eventually be recorded in TDMA. θ TDMS is recorded separately to increase the reliability of data detection. For example, during the update of TDMS, TDMS is recorded separately in a continuous cluster of TDMA, or new TDMS is recorded in the main TDMA and the new TDMS Copies are recorded in the ZDMA DMA. So far, the defect management according to the embodiment of the present invention has been described with a write-once recording medium. However, the information storage medium that can be used to implement the defect management system according to the present invention is not limited to this media type, that is, according to the present invention, it is used for information. Defect management of storage media (which uses update cycles and loop array information) is not limited to TDMS updates written to the recording media at one time.

200425081 V. Description of the invention (17) As mentioned above, irregular events (for example, the body actuator time occurred on the personal information storage medium during the recording / reading operation when recording the recording information) Any or data reading, in this case, the supply; === The recording is interrupted and the information recording is irregular and non-continuous.
