BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In the information recording / reproducing apparatus according to the present embodiment, an encrypted file (digital data) recorded in a first recording medium having a copyright protection function is recorded in a second recording medium incorporated in the information recording / reproducing apparatus. A process of saving (backing up), a process of returning (writing process) the encrypted file saved in the second recording medium to the first recording medium by copying or moving,
Is a device for performing a process of reproducing an encrypted file stored in the recording medium.

When the information recording / reproducing apparatus stores the encrypted file recorded in the first recording medium in the second recording medium, the information unique to the first recording medium (for example, I
D) and information for identifying the encrypted file (for example, file name) are created and stored in the second recording medium. Based on this list, the encrypted file is copied, moved, or saved. The feature is that it manages processing such as playback.

It should be noted that not only encrypted files but also unencrypted files are copied, moved, saved,
Playback can also be performed. Further, not only the file stored in the second recording medium but also the file recorded in the first recording medium can be reproduced. Further, not only the second recording medium but also the externally connected recording medium built in the apparatus can store the file recorded in the first recording medium. Further, not only the file stored in the second recording medium but also the file recorded in the recording medium built in the external connection device can be reproduced.

Reference numeral 10 is a reproducing unit. To the device capable of reproducing files externally connected to the information recording / reproducing device 1, the IC card 2 or the HDD
When the file recorded in No. 4 is output, the decryption processing unit 9 develops the data that can be reproduced by the external connection device, and outputs the data from the reproduction unit 10. As this output data, an image file can be output as an image signal, and an audio file can be output as an audio signal.

Reference numeral 11 denotes a reproduction discrimination processing unit for discriminating whether or not the file recorded in the IC card 2 or the HDD 4 is a copyright protection target file, for example, from the header label or extension.

Reference numeral 12 denotes a process (backup) for saving a file recorded in the IC card 2 or the HDD 4 to a device externally connected to the information recording / reproducing device 1 or a recording medium stored in the external connecting device. The data transmission system for performing the process of reproducing the existing file is shown.

FIG. 2 is a schematic view showing the outer appearance of the information recording / reproducing apparatus. However, the members corresponding to the members described with reference to FIG. 1 are denoted by the same reference numerals and the description thereof will be omitted. In FIG. 2, 13 is an insertion slot of the IC card 2, and 14
Is a button for ejecting the IC card 2, and 15 is an external terminal for connecting the information recording / reproducing apparatus 1 and an external connecting device.

When the IC card is inserted, the information recording / reproducing apparatus first acquires the unique information of the IC card. Then, when the user selects the mode for storing the files in the IC card in the HDD, the identification information of all the files in the IC card is acquired and displayed on the display unit 8. When the file to save is selected, the file is saved as H
At the same time as writing to the DD, a list including the unique information of the IC card and the identification information of the file is created and stored in the HDD. Note that the identification information of all files may be acquired at the same time that the unique information of the IC card is acquired.
Further, the identification information of all files may be obtained at the same time as the unique information of the IC card is obtained, and all the files in the IC card may be collectively stored.

The information recording / reproducing apparatus manages the processing of moving, copying, storing, and reproducing the file by using the list including the unique information of the created IC card and the identification information of the file.

For example, in the case of performing a process (copying or moving process) of writing a file stored in the HDD to an IC card, the information recording / reproducing apparatus first writes the file to be copyright protected (encrypted file). ) Is determined. When the file is a copyright protected file, the list of the file is compared with the unique information of the IC card, and it is determined whether the IC card is the IC card on which the file was originally recorded. That is, it is determined whether or not the user has a key for decrypting this cipher. If the IC card was originally recorded, the same I
Since it can be reproduced by the C card, the writing process is performed. If this is not the case, the IC card cannot reproduce the data, and therefore the writing process is not performed. The unique information of the IC card is acquired when the IC card is inserted. Alternatively, the reproduction determination processing means may not be provided, and the file list may be compared with the unique information of the IC card without determining whether the file is a copyright protection target file.

FIG. 3 shows the information recording / reproducing apparatus.
7 is a flowchart illustrating an operation when writing (copying or moving) a file in the HDD to the IC card. IC
When the card 2 is inserted, a process for obtaining the unique information of this IC card 2 is performed. The user can operate the HDD 4 from the operation unit 6.
When the mode for writing the file in the IC card 2 to the IC card 2 is selected, a list of file names stored in the HDD 4 is displayed on the display unit 8 based on the list stored in the HDD 4. When the user selects an arbitrary file from among them, the reproduction discrimination processing unit 11 performs a process for discriminating whether or not the file is a copyright protection target file (encrypted file) (step 301).

If the file is not a copyright-protected file, a process for permitting writing of the file is performed (step 304). If the file is copyright protected, the unique information of the inserted IC card 2 is compared with the list of the selected files, and the unique information of the IC card that originally recorded the selected file. Then, it is determined whether or not it matches (step 302).

If they match, it is possible to reproduce the selected file with the inserted IC card, so the process of permitting the writing of the file is performed (step 304).
If they do not match, it is impossible to reproduce the selected file with the inserted IC card, so processing is performed to prohibit writing of the file (step 303).

In this way, only files that are subject to copyright protection and files that are not subject to copyright protection that can be played back by the inserted IC card can be written to the same IC card, and files that cannot be played back by the same IC card will be mistaken. Since there is no need to write it, it is very convenient for the user.

When the user selects the mode for writing the file in the HDD 4 to the IC card 2 through the operation unit 6, the unique information of the currently inserted IC card 2 and the HD

If a file that can be played back by the C card is displayed on the display unit 8 in a state where the user can judge (for example, a file name), the user can easily judge the file that can be played back, which is convenient. It will be highly responsive.

Further, in the reproduction discrimination processing section 11, the HDD 4
All the files stored in are identified, and the display is in a state in which the user can determine which of the copyright-protected files and the non-copyright-protected files that can be played back by the inserted IC card. If it is displayed in 8 (for example,
File name), which is more convenient.

Further, as shown in FIG. 4, when a file that cannot be played back (a file whose unique information does not match) is selected, the user is instructed that it is not possible to play back even if the file is written. It is also possible to provide a step of displaying (step 403) for displaying and a step of selecting whether or not to write this file (step 404). When the writing is selected, a new list including the unique information of this IC card, the identification information of the file to be written, and the unique information of the originally recorded IC card, that is, the IC card having the key is created and stored in the HDD 4. .. If the storage destination of the file can be displayed based on this list, the convenience can be further improved. Further, when the IC card in which the unreproducible file is stored is inserted, the file name stored in the IC card is displayed using the unique information of this IC card and the list in the HDD. By doing so, the user can recognize the files stored in this IC card,
Further, it becomes possible to improve convenience.

By doing so, the storage destination of the file can be expanded not only to the HDD built in the information recording / reproducing apparatus but also to another IC card having different unique information, and the information management of the storage destination becomes possible. Therefore, the convenience is further enhanced.

Next, the operation for saving the file recorded in the IC card 2 or the HDD 4 in the recording medium built in the apparatus which is externally connected to the information recording / reproducing apparatus 1 will be described with reference to the flowchart of FIG. .

In the case of a CD-R / RW drive or the like, unique information and identification information of the recording medium (medium) will be added to the list.

When the external connection device is connected, the information recording / reproducing device acquires its unique information (eg, ID). Then, when recording the file in the HDD, the unique information of the external connection device is added to the list of the file and stored. When recording a file of an IC card, a list including identification information of the file, unique information of the IC card, and unique information of the external connection device is created and stored. Then, when the external connection device is connected, the unique information of this device is compared with the list in the HDD, and the identification information (file name) of the file stored in the recording medium built in this external connection device is displayed. By doing so, the user can recognize the file stored in the recording medium built in the external connection device. Further, when recording a file in the HDD, the identification information of the external connection device (information that allows the user to determine which external connection device) is added to the list of the file and stored, and the file in the IC card is recorded. At times, in addition to the file identification information, the IC card unique information, and the external connection device unique information, a list including the external connection device identification information is created and stored. Then, by displaying the set of the identification information of the file and the identification information of the external connection device based on this list so that the storage destination of the file can be displayed, the convenience can be further enhanced.

In this way, the storage destination of the file can be expanded not only to the HDD built in the information recording / reproducing apparatus but also to an externally connected device, and the information management of the storage destination becomes possible, which is more convenient. Will be more likely.

The process for writing a file to the IC card from the external connection device that has saved (backed up) the file as described above is the same as that for writing the file in the HDD. That is, when the external connection device is connected, the list in the HDD is compared with the unique information of the external connection device, and the identification information (file name) of the file stored in the recording medium built in the external connection device is displayed on the display unit. indicate. When the file selected from the above is written into the IC card, the reproduction discrimination processing unit performs the discrimination process of the selected file as a preceding process, and when it is discriminated that there is no copyright protection, the writing process is performed. If there is copyright protection, the unique information of the IC card currently inserted in the information recording / reproducing apparatus is compared with the list of the selected files to determine whether the unique information of the IC card matches. to decide. If they match, the same file is written. If they do not match, the file may not be written, or a display may be displayed to teach the user that the intention is that the file cannot be played even if the file is written. Further, it may be further inquired whether or not to write in the IC card. It should be noted that the reproduction identification processing unit may not be provided and the unique information of the IC card may be compared with the list of selected files.

First, when the user selects the reproduction processing mode, the display unit 8 displays the identification information (file names) of all files stored in the HDD 4. When the user selects any one of them, it is judged whether or not the file is a copyright protection target file (step 601). If it is not the subject of copyright protection, processing for reproducing the file is performed (step 606). Note that the reproduction determination processing unit may not be provided and the processing of step 601 may not be performed.

In the case of copyright protection, the inserted IC
The unique information of the card 2 is compared with the list, and a determination process as to whether or not the IC card 2 is reproducible is performed (step 602). That is, it is determined whether the unique information of the IC card 2 and the unique information of this file list match. If the file cannot be played back, the file is not played back (step 605). It should be noted that the display unit 8 may display a message for instructing the user of the intention of not being able to reproduce.

If the file is reproducible, the file is recorded in the IC card 2 and the IC card 2 is used to reproduce the file (step 603). After this process, the process of deleting the file recorded in the IC card 2 is performed (step 60
4) Then, the reproduction process ends.

As described above, the file in the HDD can be automatically reproduced. In addition, by deleting the file recorded in the IC card for reproduction after the reproduction,
Since it is possible to continuously reproduce the data larger than the capacity of the card, the convenience is enhanced.

When the user selects the reproduction processing mode, the identification information (file names) of all the files stored in the HDD 4 is displayed on the display unit 8. However, the IC card currently inserted is displayed. Further, the convenience can be further enhanced by comparing the unique information of No. 1 with all the lists stored in the HDD and displaying only those reproducible by this IC card.
