In other words, even after the optical disc is ejected and mounted on the recording / reproducing apparatus again, an opportunity for dubbing in the optical disc that can be completed in a short time can be given. Also, the copyright of the program data recorded on the HDD 15 or the optical disc can be appropriately protected.
- the recording / reproducing device 100 when the optical disc is ejected, if there is program data recorded as program data inaccessible to the user in the recording history information, later, only the recording / reproducing device 100 will activate the recording history information. In order to make it possible, the recording / reproducing apparatus 100 must be able to recognize the information only and cannot recognize it by other devices. For example, the extension attached to the file name of the program data is changed to an extension that cannot be recognized as the program data, thereby making the file unrecognizable.
- the recording / reproducing apparatus records the extension before and after the change in the nonvolatile memory 17 or the like in association with each other. Thereafter, when the optical disk is mounted, if there is program data having the changed extension in the file name, the file name of the program data is returned to the original program data extension.
- the program data having the file name whose extension is changed is not recognized as the program data, and is not normally accessed. That is, the copyright of the program data is appropriately protected.
- the optical disk containing the program data is mounted on the recording / reproducing device 100 again, the program data is recognized as invalidated program data, and the user is given another opportunity for dubbing to be completed in a short time. Can be given to
- IFO content management information
- the program data recorded as the program data inaccessible to the user is recorded in the recording history information when the optical disc is ejected. If it exists, "0" is set as the viewing permission flag in the IFO corresponding to the program data.
- the program data is data that is not recognized as program data in another recording / reproducing apparatus, and is not reproduced. Further, when the optical disk is attached to the recording / reproducing apparatus 100 again, the user can be given a chance to complete the dubbing in a short time.
- the meaning of the above-mentioned viewing permission flag is extended. If “0”, the access from the user is "non-permitted” and the data is "invisible” as data. Is also good.
- the fact that the program data is invisible means that the recording capacity of the program data is recognized as an overwritable area in another recording / reproducing apparatus and is recognized as a free capacity by the user. .
- the area where the program data with the viewing permission flag set to "0" is recorded is considered to be an overwritable recording area. Be recognized. Therefore, when recording any data on the optical disk, the program data can be deleted and used as an empty area as necessary.
- the recording history information is recorded together with the disc ID of the optical disc on which the program data was recorded, together with information for specifying the program data. Therefore, when the optical disc is mounted on the recording / reproducing apparatus 100, it is possible to confirm whether or not the program data of the optical disc has been recorded on the recording / reproducing apparatus 100. Further, the program data recorded by the recording / reproducing apparatus 100 can be specified from the program data recorded on the optical disc.
- the optical disc is mounted on the recording / reproducing apparatus 100, the optical disc is recorded. It is assumed that the playback device 100 is an optical disc on which program data has been recorded. In this case, for the program data recorded by the recording / reproducing apparatus 100, the provision of the viewing permission flag is ignored, and the recording history information is referred to. This makes it possible to determine from the recording history information whether or not the user can access the program data recorded on the optical disc. In addition, it is possible to give the user an opportunity to complete the dubbing in a short time. Note that the above-described disabling and recognizing of program data by controlling identifiers and IFOs is an example of disabling and reproducibility of the recording / reproducing apparatus of the present invention.
- FIG. 13 is a diagram showing a file structure in a Blu-ray disc.
- the BVAV directory 50 is the root directory. Also, 01000.m2ts and 020 00.dvsd existing in the stream directory 53 are program data.
- the extension “.m2ts” indicates that the format is MPEG2-TS, and the extension “.dvsd” indicates that the format is DV (Digital Video) stream.
- info and bdav existing immediately below the BVAV directory 50 are files in which management information of the entire directory is recorded. This is a directory in which files used for special playback are stored.
- the recording / reproducing apparatus 100 ejects a Blu-ray disc
- the extension of the program data “01000.m2ts” is changed to “01000. ***”.
- update info and bdav as needed. Further, these changes are stored in the nonvolatile memory 17 or the like.
- the program data can be correctly recognized only by the recording / reproducing apparatus 100.
- the program data itself may be placed in a directory other than the STREAM directory. Further, by changing a part of the recorded contents of info and bdav, a change may be made so that specific program data cannot be recognized as program data. Further, information indicating these changes may be encrypted and recorded in a predetermined location on a Blu-ray disc. In this case, key information or the like for compounding the changed contents and the information indicating the encrypted changed contents may be stored in the nonvolatile memory 17 or the like.
- the recording / reproducing apparatus 100 transmits the HDD 15 and the optical disc or the program data that is duplicatedly recorded in the optical disc to another recording / reproducing apparatus. Can not be recognized as program data.
- the program data present on the optical disc, which has been invalidated! / ⁇ may not be reproduced according to a predetermined rule without requiring the user to confirm the program data.
- program data that has been invalidated on the optical disk for a predetermined period may be deleted from the optical disk.
- the above-described processing for the optical disc and the like can be performed by any of the recording / reproducing apparatuses 100 of the first and second embodiments. Further, even in the case where the dubbing of the program data is confirmed when the optical disc is ejected as in the recording / reproducing apparatus 100 of the third embodiment, the data of the string and the data for which dubbing is not instructed is repeated again. Changes may be made to the optical disk so that dubbing can be performed after the optical disk is mounted.
- the information recorded on the recording medium such as the HDD 15 is the program data.
- information other than program data may be used, for example, audio data such as MP3 (MPEG Audio Layer-3). That is, in the recording / reproducing apparatus of the present invention, the information to be recorded and dubbed is information that can be recorded on a recording medium.
- the recording / reproducing apparatus 100 of the first to third embodiments at least one of the HDD 15 and the optical disk is provided as a recording medium.
- the recording / reproducing apparatus 100 does not need to include a recording medium.
- the HDD 15 or the optical disk drive 14 may exist as an external device, and the device and the recording / reproducing device 100 may be connected.
- the recording / reproducing apparatus can be applied to an apparatus and a method for dubbing information.
- it is useful as a DVD recorder, hard disk recorder, or Blu-ray disc recorder for recording and reproducing contents such as broadcast programs.
