The program may be configured to function on the backup device 20.

  In FIG. 1, the recording device 1 and the backup device 20 are described as separate devices. However, the recording device 1 is provided with means of the backup device 20 or an error handling program functions on the recording device 1. It is good. Moreover, the form of the recording device 1 and the backup device 20 is arbitrary. For example, the backup device 20 may be an unmanned terminal (kiosk) as shown in FIG. 2, or a dedicated set-top box as shown in FIG. 4, a portable writer as shown in FIG. 4, a DVD recorder or an HDD recorder with an arithmetic processing function as shown in FIG. 5, or a terminal equipped with a hard disk and reading of image data as shown in FIG. Or a portable device that can be separated from the main body for writing, or a car navigation device having an arithmetic processing function.

  Hereinafter, processing for the recording medium 9 in which a reading error has occurred will be described. However, in order to facilitate understanding of the present invention, a procedure for recording various data on the recording medium 9 using the recording apparatus 1 having the above-described configuration is illustrated in FIG. This will be described with reference to the flowchart of FIG.

  First, in step S101, the medium 8 is loaded into the medium loading unit 2 of the recording apparatus 1, or the digital camera 7 and the camera-equipped mobile phone 7a are connected to the device connection unit 3, and in step S102, the digital camera 7 and the medium 8 are connected. For example, data to be recorded on the recording medium 9 is selected from the read image data. Here, the image data to be read is not limited to the image data obtained by photographing with the digital camera 7, but the image data obtained by scanning a negative film or a photo print, or the moving image data obtained from a video tape recorder or the like. Still image data obtained by capturing a moving image may be used, and the reading destination may be a recording medium such as a CD-R or DVD-R or a server 10 connected via the communication network 11. Good.

  Next, in step S103, if necessary, the data generation unit 13 is used to generate (encode) moving image data based on the read image data, and can be reproduced on the home appliance based on the generated moving image data. Data (for example, video-CD format data when the moving image data is in the MPEG1 format and DVD-Video format data when the moving image data is the MPEG1 or MPEG2) is generated (authored). Further, reduced image data such as thumbnail image data or screen nail image data obtained by reducing the data size of the read image data is created as necessary.

  In step S104, the recording medium loading unit 4 is loaded with a recording medium 9 such as a CD-R / RW, DVD ± R / RW, DVD-RAM, HD-DVD, or Blu-ray disc. Although any commercially available recording medium can be used as the recording medium 9, data may be recorded only on a specific recording medium. In this case, in step S105, the recording medium is recorded. Whether or not the identification information for identifying the recording medium 12 is recorded in the predetermined area 9 is checked. If the identification information is recorded, it is determined that the recording medium 9 is a specific recording medium 9. If the contents of the identification information are easily known, the identification information itself is also copied. Therefore, at least part of the identification information is information that cannot be recorded by the computer OS, specifically information in the program memory area. It is also preferable to use information by guide groove modulation (ATIP: Absolute Time In Pre-groove) applied at the time of CD-R molding.

  Here, the structure of a general recording medium 9 (CD-R) will be described with reference to FIG. 13. The CD-R is formed on a polycarbonate substrate 100 with an organic dye layer 101 such as cyanine, phthalocyanine, or azo. A reflective layer 102 made of silver or the like and a protective layer 103 are laminated to form a pit by applying a laser beam of a predetermined power to the organic dye layer 101 to decompose the dye and deform the substrate to form pits. Recording is performed, but the laser power has an optimum value depending on the type of the laser head that irradiates the laser beam and the type of the organic dye layer 101 to be used. -The drive side needs to recognize the recommended type of R type and laser recording power. Therefore, information such as the disc application code and recommended laser recording power is written as information by guide groove modulation (ATIP) at the recording medium manufacturing stage, and this information is read by the drive firmware. The laser power is adjusted by control. Since such guide groove modulation (ATIP) can only be created at the time of manufacture, copying at the user level can be prevented. Further, lead-in start time, maximum lead-out startable time, etc., which are guide groove modulation (ATIP) other than the above, can be used as identification information by appropriately setting.

  In the present invention, since it is necessary to specify recording information such as a folder structure, folder name, file name, data type, application version information, and writing date / time information based on the identification information, the recording medium 9 is preliminarily stored. If the recorded information cannot be specified by the written identification information, identification information in which information capable of specifying the recording information is described in addition to the identification information or instead of the identification information.

  Next, various types of data are recorded on the recording medium 9 loaded in the recording medium loading unit 4 using the recording control unit 14. At this time, since the recording area in which the home appliance can read the data is limited, In the case of recording home appliance data, in step S106, the generated home appliance data is written to the inner peripheral side of the logical address area of the recording medium 9, and in step S107, the session is closed if necessary, and then step In S108, the read image data, the generated reduced image data, the application, the management data in which the identification information generated as necessary is written, etc. are written outside the home appliance data recorded at the end of the recording medium 9. Terminate the process. The logical address area is an area in which user data (program) is recorded. A program memory area, a lead-in / TOC (Table Of Contents) area, and a lead-out area in which user data arrangement information is recorded. Information areas such as disc application codes, recommended values for laser recording power, and guide groove modulation (ATIP) information areas where other information is recorded, and the area outside the logical address area is other than the above logical address area It shall refer to the area of

  For example, as shown in FIG. 12, the recording medium 9 created by the above procedure records various data, and identification information is recorded outside the innermost logical address area of the disk type recording medium 9. Data for home appliances is recorded in the area on the inner circumference of the computer as needed, and data for computer equipment such as image data, reduced image data, applications, and management data is recorded in the area on the outer circumference of the data for household appliances Is done.

  Further, the directory structure of the recording medium 9 is as shown in FIG. 11A, and image data, reduced image data, management data (index.pvm) in a folder (PS_Roll folder) indicating a storage location of image data, Computer device data is composed of slide show programs and slide show setting files in the APPL folder. When the data in the Video-CD format is generated, as shown in FIG. 11A, a file that associates the image data in the “VCD” folder as the data for the Video-CD format, and the TV screen in the “SEGMENT” folder. Data for home appliances is composed of image data to be displayed on the screen, moving image data in the “MPEGAV” folder, application for displaying still image data on the TV screen in the “DAT” folder, etc., and data in DVD-Video format. When it is generated, as shown in FIG. 11B, in the “VIDEO_TS” folder, VIDEO_TS.IFO describing chapter position information, VIDEO_TS.BUP that is a backup file thereof, and VIDEO_TS.VOB for the title selection menu. VTS _ ** _ 0.IFO describing chapter position information and its backup file. Le VTS _ ** _ 0.BUP and VTS _ ** is a moving image data of each title of VTS _ *. For home appliances data, etc. composed of video title set (VTS) in such a VOB is composed of a.

  The folder structure, the folder name, the file name, etc. are arbitrary, but in order to associate the recording structure with the identification information, for example, the identification information is YYMDyyyXXXXXXAAB (YYMD: a number specifying the date of writing, yyy: every day XXXXXX: random ID number, AA: manufacturer code (00 to ZZ), B: software, product category (0 to Z)), folder indicating the storage location of image data (PS_Roll) ), A folder indicating the storage location of data for each media 8, each device, and each film is provided in the lower hierarchy, and the name of the folder is ROYYMMDDyyy_XXXXXXAABxxx (YYMMDD: number specifying the date of writing, yyy: sequential number for each day) , XXXXXX: Random ID number, AA: Manufacturer code (00 to ZZ), B: Software, product category (0 to Z), xxx: Sequential Or a number), CCYYMMDDxxxxxx the file name of each data (CC: type of data, YYMMDD: numbers identifying the write date, xxxxxx: it is preferable to such sequential number).

  Then, the recording medium 9 created in the above procedure is reproduced using a computer device or a home appliance, and the image data or the home appliance data is browsed. As shown in the related art, the recording medium 9 is changed over time. Reading errors may occur due to deterioration or deformation, dirt or scratches attached during handling, compatibility between the recording medium 9 and the drive, etc. In such a case, data using the backup device 20 (or error handling program) Perform a backup. The procedure will be described with reference to the flowchart of FIG. In the following description, a configuration in which image data, generated data, and attached data are recorded on the recording medium 9 will be described as an example. However, a configuration in which image data and generated data are recorded may be used. Steps S212 to S213 may be omitted.

  First, in step S201, when the recording medium 9 in which the reading error has occurred is loaded in the recording medium loading unit 23 of the backup device 20, the error level determination means 25 checks the reading error of the recording medium 9 in step S202, and step S203. Thus, the error level is determined based on the check result. Specifically, for example, an error correction method called CIRC (Cross Interleave Reed-Solomon Code) is adopted in CD, and a Reed-Solomon code (C2 code) for error correction is added to the original data, and a plurality of these are added. The Reed-Solomon code (C1 code) is added again to each frame, and the error that can be recovered with the C1 code is the C1 error, the error that can be recovered with the C2 code is the C2 error, and the C2 code. However, errors that cannot be repaired are called CU errors. Therefore, the error level determination unit 25 repairs the errors in the order of the C1 code and the C2 code, and determines whether the read error of the recording medium 9 corresponds to the C1 / C2 / CU error according to the result. . The C1 / C2 / CU error can be measured by, for example, PLEXTOR disk read error check software “PLEX TOOL PROFESSIONAL”.

  If the reading error is an error that is difficult to repair (a CU error in CD-R), it is determined that backup of various data is impossible, and the process is terminated. In the case of a C2 error), in step S204, the recording information specifying unit 26 identifies the recording medium 9 generated according to a predetermined rule (identification information (physical ID) read from outside the logical address area of the recording medium 9). ) And identification information (logical ID) read from the management data, or identification information input by the user using the operation means 22), etc., folder configuration, folder name, file name, data type, application version Recording information such as information, data writing date / time information, and data writing speed information is specified.

  Here, in the conventional apparatus, it was impossible to recognize what kind of structure / name folder was originally created on the recording medium 9 and what kind of name data was recorded in each folder. In the present embodiment, by using the recording information, it is possible to specify unreadable data and also specify data associated with unreadable data. Data can be restored.

  Specifically, for example, when the identification information of the recording medium 9 is “YYMMDDyyyXXXXXXAAB”, the recording medium 9 has a ROYYMMDDyyy_XXXXXXAABxxx folder below the PS_Roll folder, as shown in FIG. As image data is recorded, thumbnail image data is recorded in the THM folder, screen nail image data is recorded in the SCREEN folder, a slideshow application is recorded in the APPL folder, and further, in the VCD folder, VIDEO_TS folder, etc. Data for home appliances in Video-CD format or DVD-Video format is recorded, and it can be determined that the file names of the original image data, thumbnail image data, and screen nail image data are CCYYMMDDxxxxxx. Therefore, the type of unreadable data can be specified by referring to the folder structure and folder name. In addition, the file name of unreadable data can be specified by referring to the file name of other data in the folder in which the unreadable data is stored, and if the file name can be specified, it is associated with the data. In addition, it is possible to specify the data, and it is possible to restore unreadable data according to the procedure described later. The specific procedure will be described below.

  First, in step S205, it is determined whether all data recorded on the recording medium 9 is unreadable. If all the data is unreadable, the recording medium 9 and the drive (recording medium loading unit 23) Since there is a possibility that a reading error has occurred due to poor compatibility, the same processing is performed using another backup device or another drive in step S206. If all the data can be read, it is not necessary to restore the data, and the process skips to step S214.

  If some of the data cannot be read, it is determined in step S207 whether the original image data (ORYYMMDDxxxxxx in FIG. 10) can be read. Since the generated data such as the business data and the reduced image data cannot be restored, the process skips to step S212.

  If all the original image data can be read, it is determined in step S208 whether generated data such as home appliance data or reduced image data can be read. If there is unreadable data, the home appliance data and the reduced image data are reproduced using the original image data by using the data restoring unit 27 in step S209.

  Specifically, when the home appliance data cannot be read, moving image data is generated (encoded) based on all the original image data, and the video-CD format or the DVD-Video is generated based on the generated moving image data. Format (HDTV format) data (authoring). If the reduced image data cannot be read, the original image data corresponding to the reduced image data that cannot be read is identified by referring to the recorded information, and the reduced image data is reproduced using the specified original image data. To do. Specifically, for example, it is checked whether the thumbnail image data (THYYMMDDxxxxxx) in the THM folder and the “xxxxxx” in the screen nail image data (SCYYMMDDxxxxxx) in the SCREEN folder are continuous. , THYYMMDD000005) is unreadable data, and the thumbnail image data is reproduced using the original image data with the same number (for example, ORYYMMDD000005).

  If part of the original image data can be read, it is determined in step S210 whether generated data such as home appliance data or reduced image data can be read, and the home appliance data or reduced image is read. If there is unreadable data in the data, the home appliance data or the reduced image data is reproduced using a part of the original image data by using the data restoring means 27 in step S211.

  Specifically, when the home appliance data cannot be read, the moving image data is generated (encoded) based on a part of the original image data, and the Video-CD format or the DVD- is generated based on the generated moving image data. Data (HDTV format) data is generated (authored). Note that in this case, the home appliance data recorded on the recording medium 9 and the home appliance data reproduced by the above procedure are not completely the same, but the original image data is not included in the home appliance. Can be played back as a slide show, enabling effective backup. If the reduced image data cannot be read, the original image data corresponding to the reduced image data that cannot be read is identified by referring to the recorded information, and the reduced image data is reproduced using the specified original image data. To do. At that time, the original image data corresponding to the unreadable reduced image data may not be read in some cases. However, since the reduced image data can be reproduced even if only part of the original image data can be reproduced, effective backup is possible.

  Next, in step S212, it is determined whether or not the attached data can be read. If there is unreadable data in the attached data, the attached data that cannot be read is used in step S213 by using the data restoring means 27. Restore the data. Specifically, it is determined whether the attached data such as the slide show program can be read from the APPL folder or the like, and if there is unreadable data, the recorded information is referred to identify the version of the attached data, and stored. The attached data of that version is read from the means 24.

  Next, in step S214, these data (if all data can be read in step S205, all the data, and if all original image data cannot be read in step S207, the generated data and attached data that can be read, If at least a part of the original image data is readable in step S207, the readable original image data, the readable generation data, and the reproduction data or the attached data restored using the original image data as necessary) Is stored in the storage means 24.

  When the recording medium 9 is taken out from the recording medium loading unit 23 and another recording medium 9a is loaded, the backup unit 28 records various data stored in the storage unit 24 on the other recording medium 9a in step S215. . At this time, the recording conditions such as the writing speed of various data and the laser power are arbitrary. For example, when all the data can be read in step S205, the same as when the data is written under the same conditions as the original recording medium 9. In order to suppress the occurrence of a read error, it is preferable to record various data under a safe recording condition such as writing at a reduced writing speed with reference to the recording information. .

  As described above, in this embodiment, the error level is determined for the recording medium 9 in which the reading error has occurred, the recording condition is specified based on the identification information for the recording medium 9 having the predetermined error level, and the generated data If the attached data cannot be read, the generated data is reproduced using the original image data or restored by reading the attached data from the storage means 24, and these data are newly recorded under the predetermined recording conditions. Since the data is backed up to the medium 9a, various data recorded on the recording medium 9 can be effectively backed up to another recording medium 9a.

  In the above description, the case where image data, generated data, and attached data are recorded on the recording medium 9 is shown, but other data may be recorded in addition to these data. In the above embodiment, the case where a reading error occurs in the recording medium on which the image data is recorded has been described. However, the present invention is not limited to the above embodiment, and other than the image data such as music data. The present invention can be similarly applied to a case where a reading error occurs in a recording medium on which this kind of data is recorded.
