[Embodiment 1]
FIG. 1 shows a system outline diagram according to the first embodiment. For example, the network 1 that is the Internet is connected to one or more personal computers 3 (PCs) and one or more servers 5 that manage a strategy data storage unit 51 that stores various strategy data. . The PC 3 may be a desktop type or a notebook type. The PC 3 includes a PC main body 31 and an optical disc drive 32 that is an optical disc recording / reproducing device. The optical disk drive 32 may be integrated with the PC main body 31 or may be externally attached via a USB (Universal Serial Bus) or the like. The PC 3 may be always connected to the network 1 or may be temporarily connected to the network 1 when necessary.

  The PC main body 31 includes a data writing unit 311, a URL (Uniform Resource Locator) management file 313, and a reference value data file 315, which are main parts of the present embodiment. The data writing unit 311 is realized by executing the data writing program according to the present embodiment by the PC main body 31. The data writing unit 311 includes a recording setting information acquisition setting unit 3111.

  The optical disk drive 32 includes a measurement processing unit 321 that performs measurement as a material for determining whether or not to acquire strategy data from the outside, in addition to main functions such as a data recording function and a data reproduction function, and a data recording A recording setting information storage unit 323 for storing recording setting information used in the function, and a recording setting information storage unit in response to an instruction from the recording setting information acquisition setting unit 3111 in the data writing unit 311 of the PC main body 31 323 includes a recording setting information writing unit 322 that performs processing for storing the recording setting information. In some cases, the optical disk drive 32 may include a reference value data storage unit 324. The reference value data is stored in the reference value data storage area 71 of the optical disc 7 and may be read by the optical disc drive 32.

  FIG. 2 schematically shows a management state of strategy data stored in the strategy data storage unit 51 managed by the server 5. The strategy data includes a plurality of parameters required for each combination of the drive ID, the media ID, the recording speed, and the measurement results described below (for example, the measurement results themselves or the difference or divergence between the reference value and the measurement results). (In the example of FIG. 2, only dTtop is shown). The parameter is a parameter in either a multi-pulse format as shown in FIG. 3 or a non-multi-pulse format as shown in FIG. For example, the multi-pulse format is adopted when the recording speed is low, and the non-multi-pulse format is adopted when the recording speed is high, or the non-multi-pulse format is adopted for all recording speeds. The multi-pulse format includes dTtop, Ttop, Tmp, Tlp, dTs, etc., as shown in FIG. Similarly, the non-multi-pal format includes dTtop, LDH, TBST, dTlast, dTs, Duty, and the like.

  Furthermore, as shown in FIG. 5, it is preferable to hold a set value for each parameter (which may be only a part) by a combination of the mark length to be recorded and the preceding space length. FIG. 5 shows the case of dTtop, and for each of the marks 2T to 6T, a set value is registered in each of the preceding space lengths from 2T to 5T. As for the code length, a necessary code length is selected according to the standard of the optical disc.

  FIG. 6 shows an example of data stored in the URL management file 313. In the example of FIG. 6, the URL of the server 5 is registered for each media ID. However, when only one server 5 is prepared in the network 1, only the URL of the server 5 is registered. For example, a server may be prepared for each optical disc manufacturer.

  The reference value data file 315 stores a reference value for the measurement results described in the following description, an allowable range threshold value, or a reference value, and an upper limit value and a lower limit value that define an allowable range from the reference value. .

  Next, the operation of the system shown in FIG. 1 will be described with reference to FIGS. First, for example, the data writing unit 311 is activated in accordance with an instruction from the user of the PC 3 (step S1). Further, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S3).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S5). In response to this, the optical disc drive 32 receives a drive ID request from the data writing unit 311 (step S7), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S9). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in the main memory, for example (step S11). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S5 to S11. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S13). The optical disc drive 32 receives the media information acquisition request (step S15), reads the media information such as the media ID from the optical disc set in step S3, and outputs it to the data writing unit 311 (step S17). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in the main memory, for example (step S19). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed. Furthermore, in this embodiment, although not used directly, in order to record the usage history of the optical disc, the media ID may be registered in a usage history management file, for example.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) and the input of recording conditions and the like is received from the user (step S21).

  Then, the data writing unit 311 determines whether to acquire strategy data from the server 5 (step S23). For example, when instructed by the user at step S21, when receiving a dedicated code as described above at step S19, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG.

  When acquiring strategy data from the server 5, the data writing unit 311 outputs a measurement instruction to the measurement processing unit 321 of the optical disc drive 32 (step S25). The measurement processing unit 321 of the optical disc drive 32 receives the measurement instruction from the data writing unit 311 (step S27), and performs the measurement process (step S29). The measurement process according to the present embodiment will be described with reference to FIG.

  In the present embodiment, the laser beam is simply applied to one place or a plurality of places on the optical disc 7 and the return light level is measured. Accordingly, the measurement processing unit 321 sets a reproduction condition in a laser driver (not shown) or the like (step S41), irradiates the reproduction laser beam onto the optical disc 7, and reflects light (return light) level from the optical disc 7. Is detected (step S43). The return light level is measured, for example, in mW units or as a reflectance (%).

  By simply detecting the reflected light level in this way, the measurement time can be shortened, so it is possible to determine early whether it is necessary to update the strategy data.

  Returning to the description of FIG. 7, the measurement processing unit 321 performs measurement results or the like (for example, when the reference value data storage unit 324 is provided or when the reference value data is read from the reference value data storage area 71 of the optical disc 7). Is output to the data writing unit 311 of the PC main body 31 (step S31). The recording setting information acquisition setting unit 3111 of the data writing unit 311 receives the measurement result and the like from the optical disc drive 32 and stores it in a storage device such as a main memory (step S33). The processing shifts to the processing in FIG.

  Shifting to the description of the processing in FIG. 9, the recording setting information acquisition setting unit 3111 reads the reference value data from, for example, the reference value data file 315 (step S51). When the reference value data is received from the optical disk drive 32, step S51 is omitted. Then, the necessity of updating the strategy data is determined from the reference value data and the measurement result (step S53). For example, using a reference value and an upper limit value (for example, + α% or [mW]) and a lower limit value (for example, −β% or [mW]) that define an allowable range from the reference value, the measurement result is within the allowable range. To determine if it is included. There may be no reference value, and it may be determined whether the measurement result is included in the allowable range based merely on the upper limit value and the lower limit value that define the allowable range. In addition, for example, an allowable range may be specified, and a range outside the allowable range may also be specified to determine whether the measurement result belongs to, for example, a first range or a second range outside the allowable range. . Further, either α or β may be 0.

  Then, when the measurement result is within the allowable range and it is not necessary to update the strategy data (step S55: No route), the process proceeds to the process of FIG. On the other hand, when the measurement result is out of the allowable range and the strategy data needs to be updated (step S55: Yes route), the recording setting information acquisition setting unit 3111 sets the URL of the server 5 holding the strategy data. For example, it reads out from the URL management file 313 (step S57). The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111 performs the drive ID acquired in step S11, the media ID acquired in step S19, the recording speed acquired in step S21, and the measurement result acquired in step S33 (or the difference from the reference value). Alternatively, the URL obtained from the strategy data request including the degree of divergence and the range to which the measurement result belongs outside the allowable range (for example, whether it exceeds the upper limit value or below the lower limit value) via the network 1 in step S57 The data is transmitted to the destination (server 5) (step S59). If the use of the server 5 is a membership system or the like, step S59 is performed after the login process is performed.

  When the server 5 receives a strategy request including the drive ID, media ID, recording speed, and measurement result from the PC 3 (step S61), the server 5 searches the strategy data storage unit 51 with the received drive ID, media ID, recording speed, and measurement result. All the corresponding strategy data is read out and transmitted to the requesting PC 3 (step S63). The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S65). The processing shifts to the processing in FIG.

  Shifting to the description of the processing in FIG. 10, the recording setting information acquisition / setting unit 3111 outputs a strategy setting command including strategy data received from the server 5 to the optical disc drive 32 (step S <b> 69). The recording setting information writing unit 322 of the optical disc drive 32 receives the strategy setting command including strategy data (step S71), and overwrites and records the strategy data in the recording setting information storage unit 323 (step S73). The received strategy data may be additionally written while the previous (for example, default) strategy data remains.

  Thereafter, the optical disc drive 32 reads out the strategy data corresponding to the media ID read out in step S17 from the recording setting information storage unit 323 and sets it as the strategy data to be used this time (step S75). Then, normal test recording (for example, OPC (Optimum Power Control)) is performed, and the optimum recording power is specified (step S77). Since a well-known method can be used for this processing, detailed description thereof is omitted. Then, the optimum recording power specified in step S77 is set as the recording power to be used this time (step S79). This completes the preparation for data recording.

  Therefore, the recording setting information writing unit 322 of the optical disc drive 32 notifies the data writing unit 311 of the PC main body 31 of the completion of setting the recording power (step S81). When the data writing unit 311 receives a recording power setting completion notification from the optical disc drive 32 (step S83), the data writing unit 311 outputs data to be recorded to the optical disc drive 32 (step S85). The optical disc drive 32 receives the recording data from the PC main body 31, and performs data recording according to the setting made above (step S87).

  On the other hand, a process when strategy data is not acquired from the server 5, that is, a process after the terminal A will be described with reference to FIG. In this case, the data writing unit 311 instructs the optical disc drive 32 to prepare for recording (step S91). When the optical disk drive 32 receives the recording preparation instruction from the PC main body 31 (step S93), the strategy data corresponding to the media ID read in step S17 is read from the recording setting information storage unit 323 and set as the strategy data used this time. (Step S95). Then, normal test recording (for example, OPC) is performed, and the optimum recording power is specified (step S97). Since a well-known method can be used for this processing, detailed description thereof is omitted. Then, the optimum recording power specified in step S97 is set as the recording power to be used this time (step S99). This completes the preparation for data recording.

  Therefore, the optical disc drive 32 notifies the data writing unit 311 of the PC main body 31 of the completion of the recording power setting (step S101). When receiving the recording power setting completion notification from the optical disk drive 32 (step S103), the data writing unit 311 outputs the data to be recorded to the optical disk drive 32 (step S105). The optical disc drive 32 receives the recording data from the PC main body 31, and performs data recording according to the setting made above (step S107).

  By executing such processing, there is a problem when the level of the reflected light from the optical disk 7 is outside the allowable range, that is, when data recording based on normal strategy data is performed on the optical disk 7 by the optical disk drive 32. When it is found that the combination is such that can occur, appropriate strategy data can be acquired from the outside, and appropriate data recording can be performed. In particular, since strategy data is acquired after simply determining whether or not there is a high possibility of a failure in the current data recording, data recording can be started early if there is no particular problem.

  In addition, although the example which acquires strategy data from the server 5 was shown above, power control information may be included. This power control information may include an OPC condition for OPC performed in step S77. The OPC conditions may include (1) set values for Pw, Pbw, Ps, Pc, and Pm shown in FIGS. 3 and 4 at the time of test recording, and (2) optimum power determination reference values.

  In the case of (1), the main power (Pw) condition includes a plurality of set values, or one reference set value and a predetermined change condition for the reference set value. The conditions other than the main power include, for example, predetermined coefficients for the main power (Pw) (εPbw, εPs, εPc, εPm. For example, Pbw = Pw × εPbw is calculated). In addition, when calculated in the form of Pbw = Pw × εPbw + α, the offset value α may be included.

  In the case of (2), the target value for each media ID (β value for DVD, asymmetry target value for Blu-ray, or modulation curve for main power (Pw). Including extrapolation condition parameters (κ, Pind, Mind, ρ, etc.).

  In addition, the power control information includes WOPC (Walking OPC: a method in which recording operation is temporarily stopped and recording is resumed after adjusting the recording power) or ROPC (Running OPC: recording power in parallel without stopping the recording operation). (Method for performing adjustment) (1) A recording power adjustment amount corresponding to a measured value (β value, asymmetry value, voltage level value, etc.) or a difference amount between the measured value and a target value according to the recording speed condition (for example, Recording power adjustment amount table or derivation formula), (2) recording power setting value according to recording speed condition (setting table or derivation formula), and (3) optimum recording power reference value according to recording speed condition.

  Furthermore, in the example described above, the strategy data corresponding to the media ID acquired in step S19 is acquired. However, for example, an optical disc that has been recorded so far before accessing the server 5 7 or the strategy data corresponding to the media ID of the optical disk 7 with which data recording is frequently performed may be acquired.

  Furthermore, in the example described above, an example is shown in which processing is performed using the reflected light level as a measurement result. For example, an index value specified based on the reflected light level (for example, a warp angle of the optical disc 7, a push-pull value, a servo error). It is also possible to change the processing to make a determination based on the signal amplitude.

[Embodiment 2]
In the first embodiment, the optical disk 7 is simply irradiated with laser light and the level of the reflected light is measured. However, the actual data recording is not the result of actual data recording. It may not necessarily represent the characteristics of. Therefore, in the present embodiment, the measurement process (FIG. 8) in step S29 is changed to the process of FIG. 12, thereby performing measurement closer to the characteristics in actual data recording and obtaining more appropriate strategy data. It shall be. The system configuration itself is the same as that of the first embodiment shown in FIG.

  The measurement processing unit 321 of the optical disc drive 32 sets the recording condition for the current measurement to a laser driver or the like (step S111), and performs test recording (step S113). Normally, data recording is performed in the test recording area of the optical disc 7, but the data recording area may be used. As for the recording conditions, a predetermined one recording power is set. In order to perform more detailed measurement, a plurality of types of recording power are set, and measurement is performed for each recording power. Also good.

  Thereafter, the reproduction condition is set to a laser driver or the like (step S115), and the reflected light (return light) level is measured by irradiating laser light according to the reproduction condition (step S117). Then, a predetermined evaluation index is calculated as a measurement result using the reflected light level (step S119).

  For the predetermined evaluation index, (1) asymmetry, (2) β value, (3) DC jitter, (4) error rate, (5) modulation degree, etc. can be used. Asymmetry is an index indicating the asymmetry of the short code and the long code in the modulation method used in each media standard, and is effective for simply evaluating the recording state. The β value and the degree of modulation are also well-known indexes that are calculated based on the amplitude level of the reproduction signal. DC jitter is an index that comprehensively indicates the amount of variation in the length of each code (mark and space) for the modulation method used in each media standard, and is effective in evaluating the recording state. The error rate is also an index representing the quality of the reproduction signal. In addition, other indexes that have been conventionally used may be used.

  The value of the evaluation index calculated in this way (including the reference value data when the reference value data storage unit 324 is provided) is used as a measurement result for the recording setting information acquisition setting unit of the data writing unit 311. It is output to 3111, and it is determined whether it is within the allowable range or outside the allowable range in relation to the reference value data.

  In this way, it is possible to determine whether or not to acquire strategy data based on the measurement result that is more suitable for the actual situation than in the first embodiment.

[Embodiment 3]
FIG. 13 shows a system outline diagram according to the present embodiment. For example, the network 1 that is the Internet is connected to one or more personal computers 3 (PCs) and one or more servers 5 that manage a strategy data storage unit 51 that stores various strategy data. . Such a basic configuration is the same as that of the first embodiment.

  The PC main body 31 includes a data writing unit 311, a URL (Uniform Resource Locator) management file 313, and an access history management file 317, which are main parts of the present embodiment. In some cases, a media ID management file 318 may be included. The data writing unit 311 is realized by executing the data writing program according to the present embodiment by the PC main body 31. The data writing unit 311 includes a recording setting information acquisition setting unit 3111.

  The optical disk drive 32 includes a recording setting information storage unit 323 for storing recording setting information used in the data recording function, and a data writing unit of the PC main body 31 in addition to main functions such as a data recording function and a data reproduction function. A recording setting information writing unit 322 that performs processing for storing the recording setting information in the recording setting information storage unit 323 according to an instruction from the recording setting information acquisition setting unit 3111 in 311;

  Next, the operation of the system shown in FIG. 13 will be described with reference to FIGS. First, for example, the data writing unit 311 is activated in accordance with an instruction from the user of the PC 3 (step S121). In addition, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S123).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S125). In response to this, the optical disc drive 32 receives the drive ID request from the data writing unit 311 (step S127), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S129). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in, for example, the main memory (step S131). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S125 to S131. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S133). The optical disc drive 32 receives the media information acquisition request (step S135), reads the media information such as the media ID from the optical disc set in step S123, and outputs it to the data writing unit 311 (step S137). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in, for example, the main memory (step S139). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) and the recording condition etc. are received from the user (step S141).

  Then, the data writing unit 311 determines whether to acquire strategy data from the server 5 (step S143). For example, when instructed by the user at step S141, when receiving a dedicated code as described above at step S139, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG.

  When acquiring strategy data from the server 5, the recording setting information acquisition setting unit 3111 of the data writing unit 311 reads the previous access date and time from the access history management file 317 (step S145). For example, data as shown in FIG. 15 is stored in the access history management file 317. That is, access date / time history data is accumulated, and the most recently registered access date / time (200705241640 in the example of FIG. 15) is read. The processing shifts to the processing in FIG.

  Moving to the description of the processing in FIG. 16, the recording setting information acquisition setting unit 3111 acquires the current time from, for example, the system clock, and determines whether a predetermined time or more has elapsed since the previous access date (step S147). If the predetermined time or more has not elapsed since the previous access date and time, it is not necessary to newly acquire strategy data this time, and the process proceeds to the process of FIG. The description of the processing after FIG. 11 is omitted.

  On the other hand, if it is determined that a predetermined time or more has elapsed from the previous access date and time, the recording setting information acquisition setting unit 3111 reads the URL of the server 5 holding the strategy data from, for example, the URL management file 313 (step S149). ). The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111 sends a strategy data request including the drive ID acquired in step S131, the media ID acquired in step S139, and the recording speed acquired in step S141 via the network 1 in step S149. It transmits to the acquired URL address (server 5) (step S151). If the use of the server 5 is a membership system or the like, step S151 is performed after the login process is performed.

  When the server 5 receives the strategy request including the drive ID, the media ID, and the recording speed from the PC 3 (step S153), the server 5 searches the strategy data storage unit 51 with the received drive ID, media ID, and recording speed, The strategy data is read and transmitted to the requesting PC 3 (step S155). In the present embodiment, strategy data is held in a data structure as shown in FIG. That is, the strategy data includes a plurality of necessary parameters (only dTtop is shown in the example of FIG. 17) for each combination of drive ID, media ID, and recording speed. The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S157). Then, the current access date and time is registered in the access history management file 317 (step S159). The processing shifts to the processing in FIG. The description after FIG. 10 is omitted.

  In step S151, not only the media ID acquired in step S139 but also the media ID of the optical disc 7 registered in the media ID management file 318 and used in the past is transmitted together. There is also. Further, data as shown in FIG. 18 may be held in the media ID management file 318, and the optical disk 7 that has been used in the past may be extracted. In FIG. 18, the order of use count, previous use date, and use count is registered for each media ID, and processing such as extracting the top five media IDs may be performed. Note that when acquiring strategy data for a plurality of media IDs, the server 5 to be accessed may be different, so steps S151 to S157 are performed for each server. Further, strategy data corresponding to a media ID other than the media ID of the optical disc 7 used this time may be written in the recording setting information storage unit 323 of the optical disc drive 32 or temporarily held in the HDD of the PC main body 31. You may make it keep.

  Further, the access history management file 317 is not as simple as shown in FIG. 15, and as shown in FIG. 19, it is more appropriate if the previous access date (or date and time) is managed for each media ID. It becomes possible to obtain the latest appropriate strategy data from the server 5 at an appropriate timing.

  By performing such processing, the server 5 is accessed when there is a high possibility that the latest strategy data has been registered after a certain amount of time has elapsed since the previous update. It is expected that there will be less access to

FIG. 20 shows a system outline diagram according to the present embodiment. The difference from the system outline diagram according to the third embodiment shown in FIG. 13 is that a data recording history management file 319 is introduced instead of the access history management file 317.

  In this data recording history management file 319, for example, the data recording date and time as shown in FIG. 21 and the presence or absence of access to the server 5 at that time are registered.

  Next, the operation of the system shown in FIG. 20 will be described with reference to FIGS. First, for example, the data writing unit 311 is activated in accordance with an instruction from the user of the PC 3 (step S161). In addition, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S163).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S165). In response to this, the optical disc drive 32 receives the drive ID request from the data writing unit 311 (step S167), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S169). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in the main memory, for example (step S171). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S165 to S171. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S173). The optical disc drive 32 receives the media information acquisition request (step S175), reads the media information such as the media ID from the optical disc set in step S163, and outputs it to the data writing unit 311 (step S177). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in the main memory, for example (step S179). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) is received, and input of recording conditions and the like is received from the user (step S181).

  Then, the data writing unit 311 determines whether to acquire strategy data from the server 5 (step S183). For example, when instructed by the user at step S181, when receiving a dedicated code as described above at step S179, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG. Description of the processing in FIG. 11 is omitted.

  When acquiring strategy data from the server 5, the recording setting information acquisition / setting unit 3111 of the data writing unit 311 reads data recording history data from the data recording history management file 319 (step S185). The processing shifts to the processing in FIG.

  Shifting to the description of the processing in FIG. 23, the recording setting information acquisition setting unit 3111 determines from the data recording history data acquired in step S185 to a predetermined condition (for example, once every five data recordings to the server 5). Access, specifically, whether or not the server 5 has been accessed in the last four data records, or access to the server 5 once in five data records within one month. It is determined whether or not the condition of at least once a month and once every 5 months when data recording is performed a plurality of times is satisfied (step S187). If it is determined that the data recording history data does not satisfy the condition (step S187: No route), the current data recording is registered in the data recording history management file 319 (step S188). And since it does not access the server 5, it transfers to the process of FIG. The description of the processing after FIG. 11 is omitted.

  On the other hand, when it is determined that the data recording history data satisfies the condition (step S187: Yes route), the recording setting information acquisition setting unit 3111 sets the URL of the server 5 holding the strategy data as, for example, URL Read from the management file 313 (step S189). The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111 sends a strategy data request including the drive ID acquired in step S171, the media ID acquired in step S179, and the recording speed acquired in step S181 via the network 1 in step S189. It transmits to the acquired URL address (server 5) (step S191). When the use of the server 5 is a membership system or the like, step S191 is performed after the login process is performed.

  When the server 5 receives the strategy request including the drive ID, the media ID, and the recording speed from the PC 3 (step S193), the server 5 searches the strategy data storage unit 51 with the received drive ID, the media ID, and the recording speed to search for all the corresponding items. The strategy data is read and transmitted to the requesting PC 3 (step S195). In the present embodiment, strategy data is held in a data structure as shown in FIG. The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S197). The current data recording date and time and access to the server 5 are registered in the data recording history management file 319 (step S199). The processing shifts to the processing in FIG. The description after FIG. 10 is omitted.

  In this way, frequent access to the server 5 can be avoided, and the latest strategy data can be acquired from the server 5 at an appropriate interval.

  As in the third embodiment, not only the media ID acquired in step S179 but also the media ID of the optical disc 7 that has been used so far or the media ID of another optical disc 7 that is frequently used. Alternatively, strategy data may be acquired.

[Embodiment 5]
Since the system schematic diagram according to the present embodiment is the same as the system schematic diagram (FIG. 1) of the first embodiment, the description thereof is omitted here. However, different processes may be performed even with the same reference numerals.

  The operation of the system shown in FIG. 1 will be described with reference to FIGS. 24 and 25 showing the processing contents according to the present embodiment. First, for example, the data writing unit 311 is activated in response to an instruction from the user of the PC 3 (step S201). In addition, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S203).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S205). In response to this, the optical disc drive 32 receives the drive ID request from the data writing unit 311 (step S207), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S209). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in the main memory, for example (step S211). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S205 to S211. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S213). The optical disc drive 32 receives the media information acquisition request (step S215), reads the media information such as the media ID from the optical disc set in step S203, and outputs it to the data writing unit 311 (step S217). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in the main memory, for example (step S219). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) and the input of recording conditions and the like is received from the user (step S221).

  Then, the data writing unit 311 determines whether to acquire strategy data from the server 5 (step S223). For example, when instructed by the user in step S221, when receiving a dedicated code as described above in step S219, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG.

  When acquiring strategy data from the server 5, the data writing unit 311 outputs a measurement instruction to the measurement processing unit 321 of the optical disc drive 32 (step S225). The measurement processing unit 321 of the optical disc drive 32 receives the measurement instruction from the data writing unit 311 (step S227), and performs temperature measurement in the optical disc drive 32 (step S229). For example, the temperature value is acquired from a sensor at a predetermined position in the optical disc drive 32. Then, the measurement processing unit 321 reads the reference value data when the measurement result or the like (for example, when the reference value data storage unit 324 is provided or when the reference value data is read from the reference value data storage area 71 of the optical disc 7). Is output to the data writing unit 311 of the PC main body 31 (step S231). The recording setting information acquisition setting unit 3111 of the data writing unit 311 receives the measurement result and the like from the optical disc drive 32 and stores it in a storage device such as a main memory (step S233). The processing shifts to the processing in FIG.

  Moving to the description of the processing in FIG. 25, the recording setting information acquisition setting unit 3111 reads the reference value data from, for example, the reference value data file 315 (step S235). When the reference value data is received from the optical disk drive 32, step S235 is omitted. Then, the necessity of updating the strategy data is determined from the reference value data and the measurement result (step S237). For example, using a reference value and an upper limit value (for example, + α% or [mW]) and a lower limit value (for example, −β% or [mW]) that define an allowable range from the reference value, the measurement result is within the allowable range. To determine if it is included. There may be no reference value, and it may be determined whether the measurement result is included in the allowable range based merely on the upper limit value and the lower limit value that define the allowable range. In addition, for example, an allowable range may be specified, and a range outside the allowable range may also be specified to determine whether the measurement result belongs to, for example, a first range or a second range outside the allowable range. . Further, either α or β may be 0.

  Then, when the measurement result is within the allowable range and the strategy data does not need to be updated (step S239: No route), the process proceeds to the process of FIG. On the other hand, when the measurement result is out of the allowable range and the strategy data needs to be updated (step S239: Yes route), the recording setting information acquisition setting unit 3111 sets the URL of the server 5 that holds the strategy data. For example, it reads out from the URL management file 313 (step S241). The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111, the drive ID acquired in step S211, the media ID acquired in step S219, the recording speed acquired in step S221, and the measurement result acquired in step S233 (or a deviation from the reference value). The strategy data request including the range to which the measurement result belongs outside the allowable range (for example, whether it exceeds the upper limit value or falls below the lower limit value) is sent to the URL acquired in step S241 via the network 1 ( To the server 5) (step S243). If the use of the server 5 is a membership system or the like, step S243 is performed after the login process is performed.

  When the server 5 receives a strategy request including the drive ID, media ID, recording speed, and measurement result from the PC 3 (step S245), the server 5 searches the strategy data storage unit 51 with the received drive ID, media ID, recording speed, and measurement result. All the corresponding strategy data is read out and transmitted to the requesting PC 3 (step S247). The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S249). The processing shifts to the processing in FIG.

  Since it is known that the recording characteristics change depending on the temperature, if the temperature is outside the allowable range, it is possible to perform appropriate data recording by acquiring and setting strategy data according to the temperature. become.

[Embodiment 6]
The system outline diagram according to the present embodiment is the same as that shown in FIG. In the present embodiment, the access history management file 317 is not used by using the media ID management file 318.

  Next, the operation of the system according to the present embodiment will be described with reference to FIGS. First, for example, the data writing unit 311 is activated in accordance with an instruction from the user of the PC 3 (step S251). In addition, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S253).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S255). In response to this, the optical disc drive 32 receives the drive ID request from the data writing unit 311 (step S257), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S259). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in, for example, the main memory (step S261). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S255 to S261. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S263). The optical disc drive 32 receives the media information acquisition request (step S265), reads the media information such as the media ID from the optical disc set in step S253, and outputs it to the data writing unit 311 (step S267). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in the main memory, for example (step S269). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) and the input of recording conditions and the like is received from the user (step S271).

  Then, the data writing unit 311 determines whether to acquire strategy data from the server 5 (step S273). For example, when instructed by the user at step S271, when receiving a dedicated code as described above at step S269, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG.

  When acquiring strategy data from the server 5, the recording setting information acquisition setting unit 3111 of the data writing unit 311 reads out a registered media ID list from which the strategy has been acquired from the server 5 from the media ID management file 318. S275). Note that not only the server 5 but also the media ID related to the strategy data written to the optical disc drive 32 together with the data writing program corresponding to the data writing unit 311 is installed in the media ID management file 318, for example. It shall be registered. Then, the processing shifts to FIG.

  Moving to the description of the processing in FIG. 27, the recording setting information acquisition setting unit 3111 determines whether the media ID acquired in step S269 is included in the registered media ID list read in step S275 ( Step S277). Then, it is determined whether the media ID acquired in step S269 is unregistered (step S279). If the media ID acquired in step S269 is already registered, it is not necessary to newly acquire strategy data this time, and the process proceeds to the process in FIG. The description of the processing after FIG. 11 is omitted.

  On the other hand, if the media ID acquired in step S269 is unregistered, the recording setting information acquisition setting unit 3111 reads the URL of the server 5 holding the strategy data from, for example, the URL management file 313 (step S281). ). The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111 sends a strategy data request including the drive ID acquired in step S261, the media ID acquired in step S269, and the recording speed acquired in step S271 via the network 1 in step S281. The acquired URL address (server 5) is transmitted (step S283). If the use of the server 5 is a membership system or the like, step S283 is performed after the login process is performed.

  When the server 5 receives the strategy request including the drive ID, the media ID, and the recording speed from the PC 3 (step S285), the server 5 searches the strategy data storage unit 51 with the received drive ID, media ID, and recording speed, The strategy data is read and transmitted to the requesting PC 3 (step S287). In the present embodiment, strategy data is held in a data structure as shown in FIG. The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S289). Then, the media ID acquired in step S269 is registered in the media ID management file 318 (step S291). The processing shifts to the processing in FIG. The description after FIG. 10 is omitted.

  If such processing is performed, the server 5 is accessed only when appropriate strategy data is not acquired. Therefore, if the optical disk 7 on which data recording has been performed is used, the server 5 Appropriate data recording can be performed quickly without access to.

[Embodiment 7]
FIG. 28 shows a system outline diagram in the present embodiment. In the present embodiment, the PC 3 is not assumed to be connected to the network 1.

  The PC main unit 31 is installed together with the data writing unit 311, the reference value data file 315, and the data writing program that is the basis of the data writing unit 311, which are the main parts of the present embodiment. And a strategy data storage unit 331 for storing a set of strategy data to be installed. The data writing unit 311 includes a recording setting information acquisition setting unit 3111. The strategy data storage unit 331 stores data similar to the data stored in the strategy data storage unit 51 in the first embodiment. However, since it is not connected to the network 1, it is not updated to the latest data.

  The optical disk drive 32 includes a measurement processing unit 321 that performs measurement as a material for determining whether or not to acquire strategy data from the outside, in addition to main functions such as a data recording function and a data reproduction function, and a data recording A recording setting information storage unit 323 for storing recording setting information used in the function, and a recording setting information storage unit in response to an instruction from the recording setting information acquisition setting unit 3111 in the data writing unit 311 of the PC main body 31 323 includes a recording setting information writing unit 322 that performs processing for storing the recording setting information.

  In such a system, FIG. 29 is implemented instead of FIG. 9 in the processing flow in the first embodiment. Therefore, the recording setting information acquisition setting unit 3111 reads the reference value data from the reference value data file 315 (step S301). When the reference value data is received from the optical disk drive 32, step S301 is omitted.

  Then, the recording setting information acquisition setting unit 3111 determines the necessity of updating the strategy data from the reference value data and the measurement result (step S303). For example, using a reference value and an upper limit value (for example, + α% or [mW]) and a lower limit value (for example, −β% or [mW]) that define an allowable range from the reference value, the measurement result is within the allowable range. To determine if it is included. There may be no reference value, and it may be determined whether the measurement result is included in the allowable range based merely on the upper limit value and the lower limit value that define the allowable range. In addition, for example, an allowable range may be specified, and a range outside the allowable range may also be specified to determine whether the measurement result belongs to, for example, a first range or a second range outside the allowable range. . Further, either α or β may be 0.

  When the measurement result is within the allowable range and the strategy data need not be updated (step S305: No route), the process proceeds to the process of FIG. On the other hand, when the measurement result is out of the allowable range and the strategy data needs to be updated (step S305: Yes route), the recording setting information acquisition setting unit 3111 determines the drive ID, media ID, recording speed, and measurement. A strategy data storage unit 331 according to a search condition including a result (or a difference or deviation from a reference value, a range to which a measurement result belongs outside the allowable range (for example, whether it exceeds an upper limit value or falls below a lower limit value)) And the strategy data corresponding to them is read (step S307). The processing shifts to the processing in FIG.

  By performing such processing, it is possible to set appropriate strategy data and perform data recording even in an environment where the network 1 is not connected.

[Embodiment 8]
In the first embodiment, it is the PC main body 31 that determines the measurement result. However, since the measurement itself is performed in the optical disk drive 32, is the reference value data held in the optical disk drive 32? Alternatively, if it is held in the reference value data storage area 71 of the optical disk 7, there is no problem even if the optical disk drive 32 makes a determination about the measurement result.

  FIG. 30 shows a system outline diagram in such a case. The difference from the system schematic diagram shown in FIG. 1 is that a reference value data storage unit 324 is provided in the optical disc drive 32 instead of the reference value data file 315, and a determination processing unit 325 is newly provided in the optical disc drive 32. It is.

  Hereinafter, the operation of the system shown in FIG. 30 will be described with reference to FIGS. 31 and 32. First, the data writing unit 311 is activated in accordance with, for example, a user instruction of the PC 3 (step S331). In addition, the user inserts an optical disk for data recording this time into the optical disk drive 32, and the optical disk drive 32 sets the optical disk to a spindle motor or the like (step S333).

  Then, the data writing unit 311 of the PC main body 31 outputs a drive ID request to the optical disc drive 32 (step S335). In response to this, the optical disc drive 32 receives the drive ID request from the data writing unit 311 (step S337), reads out the drive ID (device ID) stored in the memory of the optical disc drive 32, for example, and writes the data The data is output to the insertion unit 311 (step S339). The data writing unit 311 receives the drive ID from the optical disc drive 32 and stores it in, for example, the main memory (step S341). If there is data already acquired as configuration data of the PC 3 by an OS (Operating System) or the like, the data writing unit 311 may use the data instead of steps S335 to S341. good.

  Further, the data writing unit 311 outputs a media information acquisition request to the optical disc drive 32 (step S343). The optical disc drive 32 receives the media information acquisition request (step S345), reads the media information such as the media ID from the optical disc set in step S333, and outputs it to the data writing unit 311 (step S347). The data writing unit 311 receives the media information from the optical disc drive 32 and stores it in the main memory, for example (step S349). The media information may include a dedicated code indicating that processing such as obtaining strategy data from the server 5 is performed.

  In addition, the data writing unit 311 instructs the user about the recording conditions and the like (recording speed, whether or not to execute processing such as obtaining strategy data from the server 5 (execution, non-execution, automatic execution, etc.) Etc.) is received, and input of recording conditions and the like is received from the user (step S351).

  The data writing unit 311 determines whether to acquire strategy data from the server 5 (step S353). For example, when instructed by the user at step S351, when receiving a dedicated code as described above at step S349, or when confirming that the PC 3 is connected to the network 1, the server 5 It is determined that strategy data is acquired. In other cases, the processing shifts to the processing in FIG.

  When acquiring strategy data from the server 5, the data writing unit 311 outputs a measurement instruction to the measurement processing unit 321 of the optical disc drive 32 (step S355). The measurement processing unit 321 of the optical disc drive 32 receives the measurement instruction from the data writing unit 311 (step S357), and performs the measurement process (step S359). The measurement process according to the present embodiment is the same as that shown in FIG. 8 or FIG. However, the measurement processing unit 321 outputs the measurement result to the determination processing unit 325. Then, the processing shifts to the processing in FIG. 32 through terminals H and J.

  Shifting to the description of the processing in FIG. 32, the determination processing unit 325 reads the reference value data from the reference value data storage unit 324 (step S361). Then, the necessity of updating the strategy data is determined from the reference value data and the measurement result (step S363). For example, using a reference value and an upper limit value (for example, + α% or [mW]) and a lower limit value (for example, −β% or [mW]) that define an allowable range from the reference value, the measurement result is within the allowable range. To determine if it is included. There may be no reference value, and it may be determined whether the measurement result is included in the allowable range based merely on the upper limit value and the lower limit value that define the allowable range. In addition, for example, an allowable range may be specified, and a range outside the allowable range may also be specified to determine whether the measurement result belongs to, for example, a first range or a second range outside the allowable range. . Further, either α or β may be 0.

  Then, the determination processing unit 325 outputs the measurement result and the determination result of step S363 to the data writing unit 311 of the PC main body 31 (step S365). The recording setting information acquisition setting unit 3111 in the data writing unit 311 of the PC main body 31 receives the measurement result and the determination result from the optical disc drive 32 (step S367). The recording setting information acquisition setting unit 3111 determines whether the determination result indicates that the strategy data needs to be updated (step S369), and if the determination result indicates that the update is not required. Then, the processing shifts to the processing in FIG. On the other hand, if the determination result indicates that updating is required, the recording setting information acquisition setting unit 3111 reads the URL of the server 5 holding the strategy data from, for example, the URL management file 313 (step S371). . The URL of the server 5 may be managed by the PC main body 31 or may be stored in the memory of the optical disc drive 32 and may be received from the optical disc drive 32 together with media information, for example.

  Thereafter, the recording setting information acquisition setting unit 3111 determines the drive ID, the media ID, the recording speed, and the measurement result (or the deviation from the reference value, the range to which the measurement result belongs outside the allowable range (for example, exceeds the upper limit value or A strategy data request including whether it is below the lower limit value) is transmitted to the acquisition URL address (server 5) via the network 1 (step S373). If the use of the server 5 is a membership system or the like, step S373 is performed after the login process is performed.

  When the server 5 receives a strategy request including the drive ID, media ID, recording speed, and measurement result from the PC 3 (step S375), the server 5 searches the strategy data storage unit 51 with the received drive ID, media ID, recording speed, and measurement result. All the corresponding strategy data is read out and transmitted to the requesting PC 3 (step S377). The recording setting information acquisition setting unit 3111 of the data writing unit 311 in the PC 3 receives the corresponding strategy data from the server 5 and temporarily stores it in, for example, a hard disk drive (step S379). The processing shifts to the processing in FIG.

  By adopting such a configuration, the configuration of the data writing unit 311 is simplified.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the features according to the embodiments can be combined. For example, the characteristics according to the eighth embodiment can be applied to the second embodiment.

  Furthermore, the functional block diagram may not necessarily correspond to an actual program module.

  In the case where the measurement process is performed, a process for determining whether the media ID is camouflaged may also be performed. That is, it is determined whether or not a measurement result (for example, reflectance) that does not occur in the genuine optical disc 7 corresponding to the specific media ID is generated. For example, a reference value for authenticity determination and allowable range data may be stored, and if it falls outside the allowable range, a warning may be issued because the media ID is camouflaged. When a warning is issued, the user is prompted to stop data recording. However, if the user instructs, data recording may be performed using standard strategy data.

  The PC 3 and the server 5 are, for example, computer devices, and in the computer device, as shown in FIG. 33, a memory 2501 (storage unit), a CPU 2503 (processing unit), a hard disk drive (HDD) 2505, and a display device. A display control unit 2507 connected to 2509, a drive device 2513 for the removable disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network are connected by a bus 2519. Application programs including an operating system (OS) and a Web browser are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. If necessary, the CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 to perform necessary operations. Further, data in the middle of processing is stored in the memory 2501 and stored in the HDD 2505 if necessary. Such a computer realizes various functions as described above by organically cooperating hardware such as the CPU 2503 and the memory 2501 described above with the OS and necessary application programs.
