[0040] まず、ステップ S 1にお 、て、情報記録再生装置 2の制御部 20は、通信可能通知を 要求するための通信要求を送信するように通信部 22に指示し、通信部 22は、通信 要求を RFIDタグ 3へ送信する。次に、制御部 20は、通信部 22が通信可能通知を受 信した力否かを判断し、通信可能通知を受信しない場合、ステップ S1に戻って通信 要求を再度送信し、通信可能通知を受信した場合、ステップ S3へ処理を移行する。  First, in step S 1, the control unit 20 of the information recording / reproducing apparatus 2 instructs the communication unit 22 to transmit a communication request for requesting a communicable notification, and the communication unit 22 , Send a communication request to RFID tag 3. Next, the control unit 20 determines whether or not the communication unit 22 has received the communication enable notification. If the communication unit 22 does not receive the communication enable notification, the control unit 20 returns to step S1 and transmits the communication request again to transmit the communication enable notification. If it is received, the process proceeds to step S3.
[0041] なお、情報記録再生装置 2の通信部 22と RFIDタグ 3との位置関係が通信可能範 囲外にある場合、 RFIDタグ 3は、情報記録再生装置 2からの通信要求を受信するこ とができないため、通信可能通知を送信することはできない。この場合、情報記録再 生装置 2の制御部 20は、通信可能通知を受信していないと判断してステップ S 1へ処 理を移行する。  When the positional relationship between the communication unit 22 of the information recording / reproducing device 2 and the RFID tag 3 is out of the communicable range, the RFID tag 3 receives the communication request from the information recording / reproducing device 2. It is not possible to send a communicable notification because it is impossible. In this case, the control unit 20 of the information recording and reproducing apparatus 2 determines that the communication enable notification has not been received, and shifts the processing to step S1.
[0042] 一方、情報記録再生装置 2と RFIDタグ 3との位置関係が通信可能範囲にある場合 、ステップ S 11において、 RFIDタグ 3の通信部 304は、通信要求を受信して制御部 3 01へ出力する。次に、ステップ S12において、制御部 301は、通信可能状態にある ことを通知するための通信可能通知を送信するように通信部 304に指示し、通信部 3 04は、通信可能通知を情報記録再生装置 2へ送信する。この場合、情報記録再生 装置 2の制御部 20は、通信可能通知を受信したと判断してステップ S3へ処理を移行 する。  On the other hand, when the positional relationship between the information recording / reproducing apparatus 2 and the RFID tag 3 is within the communicable range, the communication unit 304 of the RFID tag 3 receives the communication request and controls the unit in step S11. Output to Next, in step S12, the control unit 301 instructs the communication unit 304 to transmit a communicable notification for notifying that it is in the communicable state, and the communication unit 304 can record the communicable notification as an information record.

[0047] 次に、ステップ S4において、制御部 20は、通信部 22に管理情報を送信するように 指示し、通信部 22は、管理情報を RFIDタグ 3へ送信する。なお、ディスク情報が RF IDタグ 3の ROM302に予め記録されている場合、このディスク情報は送信する必要 はなぐディスク情報以外の管理情報のみが読み出されて送信される。 Next, in step S4, the control unit 20 instructs the communication unit 22 to transmit the management information, and the communication unit 22 transmits the management information to the RFID tag 3. When the disc information is recorded in advance in the ROM 302 of the RF ID tag 3, only the management information other than the disc information which is necessary to be transmitted is read and transmitted.
[0048] 次に、ステップ S13において、 RFIDタグ 3の通信部 304は、管理情報を受信して制 御部 301へ出力する。次に、ステップ S14において、制御部 301は、管理情報を RW M303へ記憶する。  Next, in step S 13, the communication unit 304 of the RFID tag 3 receives the management information and outputs the management information to the control unit 301. Next, in step S14, the control unit 301 stores management information in the RW M 303.
[0049] このように、光ディスク ODに設けられた RFIDタグ 3が備える RWM303は、光ディ スク ODに情報を記録及び Z又は再生するための記録媒体情報を記憶し、光デイス ク ODに情報を記録する、及び Z又は光ディスク OD力 情報を再生する情報記録再 生装置 2は、 RFIDタグ 3の RWM303に記録媒体情報を書き込む。 Thus, the RWM 303 included in the RFID tag 3 provided on the optical disc OD stores recording medium information for recording and Z or reproducing information on the optical disc OD, and stores the information on the optical disc OD. Information recording and reproducing, and recording and reproducing Z or optical disc OD force information The raw device 2 writes the recording medium information to the RWM 303 of the RFID tag 3.
[0050] したがって、光ディスク OD又は情報記録再生装置 2だけではなぐ光ディスク OD に設けられた RFIDタグ 3に、光ディスク ODに情報を記録及び/又は再生するため の記録媒体情報を記憶させることにより、光ディスク OD又は情報記録再生装置 2の みに情報を記録させる場合に比して情報の保守性を向上させることができる。 Therefore, an optical disc can be obtained by storing recording medium information for recording and / or reproducing information in the optical disc OD in the RFID tag 3 provided on the optical disc OD which is not the only of the optical disc OD or the information recording / reproducing apparatus 2. As compared with the case where information is recorded only in the OD or the information recording / reproducing apparatus 2, the maintainability of the information can be improved.
[0051] また、光ディスク ODに情報を記録及び Z又は再生するために必要不可欠な管理 情報が RFIDタグ 3の RWM303に記憶されるので、光ディスク ODだけではなぐ光 ディスク ODに設けられた RFIDタグ 3に管理情報を記憶させることにより、光ディスク ODのみに管理情報を記録させる場合に比して管理情報の保守性を向上させること ができる。 [0051] Further, since the management information necessary for recording and reproducing information on the optical disc OD and reproducing the information is stored in the RWM 303 of the RFID tag 3, the RFID tag provided on the optical disc OD which can not be obtained by the optical disc OD alone 3 By storing the management information in the storage medium, the maintainability of the management information can be improved as compared with the case where the management information is recorded only on the optical disc OD.
[0052] また、光ディスク ODの種別を特定するための識別情報が RFIDタグ 3の RWM303 に記憶されるので、光ディスク ODだけではなぐ光ディスク ODに設けられた RFIDタ グ 3に識別情報を記憶させることにより、光ディスク ODのみに識別情報を記録させる 場合に比して識別情報の保守性を向上させることができる。  Further, since the identification information for identifying the type of the optical disc OD is stored in the RWM 303 of the RFID tag 3, the identification information is stored in the RFID tag 3 provided in the optical disc OD which is not only the optical disc OD. Thus, the maintainability of the identification information can be improved as compared with the case where the identification information is recorded only on the optical disc OD.
[0053] また、光ディスク ODの欠陥を管理する欠陥管理情報が RFIDタグ 3の RWM303に 記憶されるので、光ディスク ODだけではなぐ光ディスク ODに設けられた RFIDタグ 3に欠陥管理情報を記憶させることにより、光ディスク ODのみに欠陥管理情報を記 録させる場合に比して欠陥管理情報の保守性を向上させることができる。  Further, since defect management information for managing defects in the optical disk OD is stored in the RWM 303 of the RFID tag 3, the defect management information is stored in the RFID tag 3 provided on the optical disk OD which is not only the optical disk OD. Compared with the case where defect management information is recorded only on the optical disc OD, the maintainability of the defect management information can be improved.
[0054] さらに、光ディスク ODに記録される情報に関するファイルシステム情報が RFIDタグ 3の RWM303に記憶されるので、光ディスク ODだけではなぐ光ディスク ODに設け られた RFIDタグ 3にファイルシステム情報を記憶させることにより、光ディスク ODの みにファイルシステム情報を記録させる場合に比してファイルシステム情報の保守性 を向上させることができる。  Furthermore, since file system information related to information recorded in the optical disc OD is stored in the RWM 303 of the RFID tag 3, the file system information is stored in the RFID tag 3 provided in the optical disc OD which is not only the optical disc OD. Thus, the maintainability of file system information can be improved as compared with the case where file system information is recorded only on the optical disk OD.
[0055] さらにまた、光ディスク ODに記録される情報を用いて実行されるアプリケーションに 関するアプリケーションシステム情報が RFIDタグ 3の RWM303に記憶されるので、 光ディスク ODだけではなぐ光ディスク ODに設けられた RFIDタグ 3にアプリケーショ ンシステム情報を記憶させることにより、光ディスク ODのみにアプリケーションシステ ム情報を記録させる場合に比してアプリケーションシステム情報の保守性を向上させ ることがでさる。 Furthermore, since application system information related to the application to be executed using the information recorded in the optical disc OD is stored in the RWM 303 of the RFID tag 3, the RFID tag provided in the optical disc OD which is not only the optical disc OD By storing the application system information in (3), the maintainability of the application system information is improved as compared with the case where the application system information is recorded only in the optical disk OD. It is possible to
[0056] また、別の例として、図示しな 、が、光ディスク ODに記録されて 、る管理情報が正 常であるか否かに関わらず、常に RFIDタグ 3から読み出した管理情報を用いるよう にしてもよい。こうすることで、光ディスク ODから管理情報を読み取り、読み取った管 理情報が正常である力否かを判定するまでの処理を略し、力かる時間を短縮すること が可能となる。  Also, as another example, not shown is to always use the management information read out from the RFID tag 3 regardless of whether the management information is recorded properly on the optical disc OD or not. You may By doing this, it is possible to omit the process of reading the management information from the optical disc OD and determining whether the read management information is normal or not, and to reduce the time required for the operation.
[0057] たとえば当該情報記録再生装置が、複数種類の光ディスク ODを扱う場合 (例えば 、 CD、 DVD, BDに対して全て記録再生する機能を有する場合、 ROMディスク、 R AMディスクの両方を扱う場合)や、光ディスク ODが複数の物理領域を有する場合 ( 例えば、二つの記録層を有する記録型 BDディスクや、 CDフォーマットの記録層と D VDフォーマットの記録層を両方有する光ディスク媒体などの場合)を想定してみる。  For example, when the information recording and reproducing apparatus handles multiple types of optical disc OD (for example, when it has a function to record and reproduce all on CD, DVD, and BD, and when both ROM disc and RAM disc are handled) And optical disc OD has a plurality of physical areas (for example, a recordable BD disc having two recording layers, and an optical disc medium having both a recording layer of a CD format and a recording layer of a DVD format). Let's assume.
[0058] 従来の装置では、コンテンツの記録 Z再生の対象となっている光ディスク ODが如 何なる種別の媒体であるかを判別するために、カートリッジの有無を判別したり、カー トリッジ無の場合には、実際に光ディスク ODにレーザを照射し反射光力も再生信号 を読み取ることにより判別を行っていた。し力しながら、光ディスク ODの種別により記 録再生に必要なレーザの波長が異なったり、ディスクの構造が異なるためレンズの N Aなど光学系の構成を切り替えたり、フォーカスやトラッキングなどサーボ方式を切り 替えたりしないと、信号が再生できないなど、複数種類の光ディスクからその種別を 判定するために相当の処理が必要となって 、た。  In the conventional apparatus, in order to determine what type of medium the optical disk OD targeted for recording Z reproduction of content is of, the presence or absence of a cartridge is determined, or in the case of no cartridge. In fact, the optical disc OD was actually irradiated with a laser and the reflected light power was also determined by reading the reproduction signal. Depending on the type of optical disc OD, the wavelength of the laser required for recording and reproduction may differ, or the disc structure may differ, and the optical system configuration such as lens NA may be switched, or servo methods such as focusing and tracking may be switched. Otherwise, the signal could not be reproduced, and considerable processing was required to determine the type of multiple optical discs.
[0059] これに対し、実施例の構成では、 RFIDタグ 3から読み出した管理情報によって、光 ディスク ODに記録された情報を読み取ることなく種別を特定することができるので、 諸々の構成要素を切替ながらの煩雑な処理手順を省略することが可能となり、光ディ スク ODを起動しコンテンツの記録 Z再生を開始するまでに力かる時間を大幅に短縮 することち可會となる。  On the other hand, in the configuration of the embodiment, the management information read out from the RFID tag 3 can identify the type without reading the information recorded in the optical disc OD, so that various components are switched. While it is possible to omit complicated processing procedures, it is possible to significantly reduce the time required to activate the optical disk OD and start the recording Z reproduction of the content.

[0126] 次に、ステップ S173において、 RFIDタグ 3の通信部 304は、コンテンツ記録位置 情報送信要求を受信して制御部 301へ出力する。次に、ステップ S174において、制 御部 301は、 RWM303に記憶されているコンテンツ記録位置情報を読み出す。次 に、ステップ S175において、制御部 301は、通信部 304にコンテンツ記録位置情報 を送信するように指示し、通信部 304は、コンテンツ記録位置情報を情報記録再生 装置 2へ送信する。 Next, in step S 173, the communication unit 304 of the RFID tag 3 receives the content recording position information transmission request and outputs the request to the control unit 301. Next, in step S174, the control unit 301 reads out the content recording position information stored in the RWM 303. Next, in step S175, the control unit 301 instructs the communication unit 304 to transmit the content recording position information, and the communication unit 304 transmits the content recording position information to the information recording / reproducing apparatus 2.
[0127] 次に、ステップ S165において、情報記録再生装置 2の通信部 22は、コンテンツ記 録位置情報を受信して制御部 20へ出力する。次に、ステップ S166において、制御 部 20は、コンテンツ記録位置情報に基づいて、記録及び再生インターフェース部 14 を介して可換記録媒体記録部 15を制御し、光ディスク ODにコンテンツを記録する。 具体的には、コンテンツ記録位置情報には、光ディスク ODに記録されているコンテ ンッの終了位置を表す終了位置アドレスが含まれており、制御部 20は、この終了位 置アドレスの次のアドレスに対応する位置に光ピックアップを移動させ、新たなコンテ ンッの記録を開始する。  Next, in step S 165, the communication unit 22 of the information recording / reproducing apparatus 2 receives the content recording position information and outputs it to the control unit 20. Next, in step S166, the control unit 20 controls the removable recording medium recording unit 15 via the recording and reproduction interface unit 14 based on the content recording position information, and records the content on the optical disc OD. Specifically, the content recording position information includes an end position address indicating the end position of the content recorded on the optical disc OD, and the control unit 20 sets the address next to the end position address. Move the optical pickup to the corresponding position and start recording a new content.
[0128] このように、光ディスク ODに次に記録すべきコンテンツデータの光ディスク OD上の 記録位置を特定するためのコンテンツ記録位置情報が RFIDタグ 3に記憶されており 、光ディスク ODに設けられた RFIDタグ 3からコンテンツ記録位置情報が読み出され 、読み出されたコンテンツ記録位置情報に基づ 、て新たなコンテンツデータが光ディ スク ODに記録される。なお、コンテンツ記録位置情報は、光ディスク ODに記録され ているコンテンツの光ディスク ODの記録可能領域における最後のアドレス、又は次 に記録が可能な領域の候補を示す情報などを含む。  As described above, the RFID tag 3 stores the content recording position information for specifying the recording position on the optical disc OD of the content data to be recorded next to the optical disc OD, and the RFID provided on the optical disc OD Content recording position information is read out from the tag 3 and new content data is recorded on the optical disc OD based on the read out content recording position information. The content recording position information includes the last address in the recordable area of the optical disc OD of the content recorded on the optical disc OD, or information indicating a candidate of the area which can be recorded next.
[0129] したがって、新たなコンテンツデータを光ディスク ODに記録する場合に、光ディスク ODの記録可能な領域を探索することが不要となり、 RFIDタグ 3から読み出されたコ ンテンッ記録位置情報に基づいて新たなコンテンツデータを光ディスク ODに記録す ることがでさる。  Therefore, when new content data is recorded on the optical disk OD, searching for the recordable area of the optical disk OD is unnecessary, and new recording of position information read out from the RFID tag 3 is performed based on the content recording position information. Content data can be recorded on the optical disc OD.
[0130] 次に、書き換え回数の多い情報を RFIDタグ 3に書き込む情報書き込み処理につ いて説明する。図 13は、書き換え回数の多い情報を RFIDに書き込む情報書き込み 処理につ 、て説明するためのフローチャートである。 Next, an information writing process for writing information with a large number of times of rewriting in the RFID tag 3 will be described. Explain. FIG. 13 is a flowchart for explaining an information writing process of writing information with a large number of rewrites into the RFID.
[0131] まず、ステップ S181において、情報記録再生装置 2の制御部 20は、コンテンツの 記録又は再生指示を受け付ける。ユーザは、操作部 21を用いてコンテンツの記録又 は再生を指示する。 First, in step S181, the control unit 20 of the information recording / reproducing apparatus 2 receives an instruction for recording or reproducing content. The user instructs the recording or reproduction of the content using the operation unit 21.
[0132] 次に、ステップ S182において、制御部 20は、記録及び再生インターフェース部 14 を介して可換記録媒体記録部 15を制御し、コンテンツを記録又は再生する。操作部 21によりコンテンツの記録が指示された場合、ステップ S 182において、制御部 20は 、記録及び再生インターフェース部 14を介して可換記録媒体記録部 15を制御し、光 ディスク ODにコンテンツを記録する。また、操作部 21によりコンテンツの再生が指示 された場合、ステップ S182において、制御部 20は、記録及び再生インターフェース 部 14を介して可換記録媒体記録部 15を制御し、光ディスク ODに記録されて 、るコ ンテンッを再生する。  Next, in step S 182, the control unit 20 controls the removable recording medium recording unit 15 via the recording and reproduction interface unit 14 to record or reproduce the content. When the recording of the content is instructed by the operation unit 21, in step S 182, the control unit 20 controls the removable recording medium recording unit 15 via the recording and reproduction interface unit 14 to record the content on the optical disc OD. Do. Also, when reproduction of content is instructed by the operation unit 21, in step S 182, the control unit 20 controls the exchangeable recording medium recording unit 15 via the recording and reproduction interface unit 14 to record on the optical disc OD. , To play the content.
[0133] 次に、ステップ S183において、制御部 20は、コンテンツが記録又は再生された結 果、管理情報が書き換えられたか否かを判断する。なお、本実施の形態では、管理 情報の一部が書き換えられた場合であっても管理情報が書き換えられたと判断する Next, in step S183, the control unit 20 determines whether the management information has been rewritten as a result of the content being recorded or reproduced. In the present embodiment, even if a part of the management information is rewritten, it is determined that the management information is rewritten.
。ここで、管理情報が書き換えられていないと判断された場合 (ステップ S183で NO) 、ステップ S181の処理に戻る。 . Here, if it is determined that the management information has not been rewritten (NO in step S183), the process returns to the process of step S181.
[0134] 一方、管理情報が書き換えられたと判断された場合 (ステップ S 183で YES)、ステ ップ S184において、制御部 20は、記録及び再生インターフェース部 14を介して可 換記録媒体記録部 15を制御し、光ディスク ODに記録されて 、る書き換え回数を読 み出す。なお、本実施の形態では、書き換え回数を光ディスク ODに記録するとして いるが、本発明は特にこれに限定されず、情報記録再生装置 2が備える EEPROM に記憶してもよぐまた、 RFIDタグ 3の RWM303に記憶してもよい。  On the other hand, when it is determined that the management information has been rewritten (YES in step S 183), in step S 184, control unit 20 controls exchangeable recording medium recording unit 15 via recording and reproduction interface unit 14. Is recorded on the optical disk OD, and reads out the number of rewrites. In the present embodiment, although the number of rewrites is recorded on the optical disc OD, the present invention is not particularly limited to this, and may be stored in the EEPROM of the information recording / reproducing apparatus 2. It may be stored in RWM303.
[0135] 次に、ステップ S185において、制御部 20は、書き換え回数が予め設定されている 所定回数以上であるか否かを判断する。なお、所定回数は、光ディスクの書き換え可 能な回数、例えば、 1万回〜 9万回に設定される。書き換え可能な回数は、光デイス クの種類毎に異なるため、光ディスクの種類毎に所定回数を設定してもよ 、。 [0136] ここで、書き換え回数が予め設定されて 、る所定回数より少な 、と判断された場合 ( ステップ S185で NO)、ステップ S189において、制御部 20は、記録及び再生インタ 一フェース部 14を介して可換記録媒体記録部 15を制御し、光ディスク ODに記録さ れて 、る管理情報を書き換える。 Next, in step S185, control unit 20 determines whether or not the number of times of rewriting is equal to or greater than a predetermined number of times set in advance. The predetermined number of times is set to the number of times the optical disc can be rewritten, for example, 10,000 to 90,000 times. Since the number of times of rewriting is different for each type of optical disk, a predetermined number of times may be set for each type of optical disk. Here, if it is determined that the number of rewrites is set in advance and is less than the predetermined number (NO in step S 185), control unit 20 controls recording / reproducing interface unit 14 in step S 189. The exchangeable recording medium recording unit 15 is controlled via the interface to rewrite the management information recorded on the optical disc OD.
[0137] 次に、ステップ S190において、制御部 20は、記録及び再生インターフェース部 14 を介して可換記録媒体記録部 15を制御し、光ディスク ODに記録されて 、る書き換 え回数を 1だけインクリメントして記憶する。  Next, in step S190, the control unit 20 controls the exchangeable recording medium recording unit 15 via the recording and reproduction interface unit 14 to record on the optical disc OD, and the number of rewrites is one. Increment and store.
[0138] 一方、書き換え回数が予め設定されている所定回数以上であると判断された場合（ ステップ S185で YES)、ステップ S186, S187, S191, S 192の処理力行われる。 なお、このステップ S186, S187, S191, S192の処理 ίま、図 4に示すステップ S1, S2, Sl l, S12の処理と同じであるので説明を省略する。  On the other hand, if it is determined that the number of times of rewriting is equal to or more than the predetermined number of times set in advance (YES in step S185), processing powers of steps S186, S187, S191, and S192 are performed. The processing of steps S186, S187, S191, and S192 is the same as the processing of steps S1, S2, S11, and S12 shown in FIG.
[0139] 次に、ステップ S188において、制御部 20は、通信部 22に管理情報を送信するよう に指示し、通信部 22は、管理情報を RFIDタグ 3へ送信する。  Next, in step S188, the control unit 20 instructs the communication unit 22 to transmit the management information, and the communication unit 22 transmits the management information to the RFID tag 3.
[0140] 次に、ステップ S193において、 RFIDタグ 3の通信部 304は、管理情報を受信して 制御部 301へ出力する。次に、ステップ S194において、制御部 301は、管理情報を RWM303へ記憶する。  Next, in step S 193, the communication unit 304 of the RFID tag 3 receives the management information and outputs the management information to the control unit 301. Next, in step S194, the control unit 301 stores management information in the RWM 303.
[0141] このように、光ディスク ODにおける情報 (管理情報)の書き換え回数が所定回数以 上の情報が RFIDタグ 3に記憶されるので、光ディスク ODの劣化を防止することがで き、より多くの情報を光ディスク ODに記録することができる。  As described above, the RFID tag 3 stores information whose number of rewrites of information (management information) in the optical disc OD is equal to or more than a predetermined number, so that deterioration of the optical disc OD can be prevented. Information can be recorded on the optical disc OD.
[0142] なお、本実施の形態では、書き換え回数に応じて管理情報を光ディスク ODと RFI Dタグ 3とのいずれかに記憶しているが、本発明は特にこれに限定されず、管理情報 の一部を書き換え回数に応じて光ディスク ODと RFIDタグ 3とのいずれかに記憶して もよい。また、管理情報だけでなぐアクセス履歴情報、コンテンツ再生履歴情報及び 起動情報などを書き換え回数に応じて光ディスク ODと RFIDタグ 3とのいずれかに記 憶してもよい。  In the present embodiment, the management information is stored in either of the optical disc OD and the RFID tag 3 according to the number of rewrites, but the present invention is not particularly limited to this, and management information A part may be stored in either the optical disc OD or the RFID tag 3 according to the number of times of rewriting. Further, access history information, content reproduction history information, activation information and the like which are not only management information may be stored in either the optical disc OD or the RFID tag 3 according to the number of times of rewriting.
[0143] また、本実施の形態では、書き換え回数に応じて管理情報の記録場所を光ディスク ODと RFIDタグ 3とに切り替えている力 本発明は特にこれに限定されず、予め書き 換え回数が多 、とわ力つて 、る管理情報につ!/ヽては光ディスク ODではなぐ RFID タグ 3に記憶するように構成してもよい。例えば、管理情報の中でも欠陥管理情報は 書き換え回数が多いので、光ディスク ODではなぐ RFIDタグ 3に記憶するようにして ちょい。 Further, in the present embodiment, the present invention is not particularly limited to the present invention in which the recording location of management information is switched between the optical disc OD and the RFID tag 3 according to the number of rewrites. Management information about the management information! / は 光 デ ィ ス ク 光 デ ィ ス ク 光 デ ィ ス ク OD OD RFID RFID RFID It may be configured to be stored in the tag 3. For example, since defect management information is frequently rewritten among the management information, it is preferable to store it in the RFID tag 3 which is not in the optical disk OD.
[0144] さらに、本実施の形態では、記憶する情報量の大きさに応じて管理情報の記録場 所を光ディスク ODと RFIDタグ 3とに切り替えてもよい。例えば、記憶すべき管理情報 の情報量が予め設定されている所定量以上である場合、光ディスク ODに記録し、記 憶すべき管理情報の情報量が予め設定されて 、る所定量より少な 、場合、 RFIDタ グ 3に書き込む。  Furthermore, in the present embodiment, the recording location of the management information may be switched between the optical disc OD and the RFID tag 3 according to the size of the amount of information to be stored. For example, when the amount of management information to be stored is equal to or greater than a predetermined amount set in advance, the amount of management information to be stored is set in advance and is smaller than the predetermined amount. If so, write to RFID tag 3.
[0145] 続いて、光ディスクに記録された情報と、 RFIDタグ 3に記録された情報とのうち、最 新の情報を読み出す情報読み出し処理について説明する。図 14は、光ディスクに記 録された情報と、 RFIDタグ 3に記録された情報とのうち、最新の情報を読み出す情 報読み出し処理について説明するためのフローチャートである。  Subsequently, an information reading process for reading the latest information out of the information recorded on the optical disc and the information recorded on the RFID tag 3 will be described. FIG. 14 is a flow chart for explaining an information reading process for reading the latest information among the information recorded on the optical disc and the information recorded on the RFID tag 3.
[0146] まず、ステップ S 201にお 、て、情報記録再生装置 2の制御部 20は、記録及び再 生インターフェース部 14を介して可換記録媒体記録部 15を制御し、光ディスク OD に記録されている記録時刻 Taを読み出す。なお、本実施の形態における記録時刻 Taは、光ディスク ODに管理情報が最後に記録された時刻を表している。  First, in step S 201, the control unit 20 of the information recording / reproducing apparatus 2 controls the exchangeable recording medium recording unit 15 via the recording and reproduction interface unit 14 and records the information on the optical disc OD. Reads out the recording time Ta. The recording time Ta in the present embodiment represents the time at which the management information was last recorded on the optical disc OD.
[0147] 次に、ステップ S202, S203, S221, S222の処理力 S行われる。なお、このステップ S202, S203, S221, S222の処理は、図 4に示すステップ SI, S2, Sl l, S12の 処理と同じであるので説明を省略する。  Next, the processing power S of steps S 202, S 203, S 221 and S 222 is performed. The processing in steps S202, S203, S221, and S222 is the same as the processing in steps SI, S2, S11, and S12 shown in FIG.
[0148] 次に、ステップ S 204において、制御部 20は、通信部 22に記録時刻送信要求を送 信するように指示し、通信部 22は、記録時刻送信要求を RFIDタグ 3へ送信する。  Next, at step S 204, the control unit 20 instructs the communication unit 22 to transmit a recording time transmission request, and the communication unit 22 transmits the recording time transmission request to the RFID tag 3.
[0149] 次に、ステップ S223において、 RFIDタグ 3の通信部 304は、記録時刻送信要求を 受信して制御部 301へ出力する。次に、ステップ S224において、制御部 301は、 R WM303に記憶されている記録時刻 Tbを読み出す。なお、本実施の形態における 記録時刻 Tbは、 RFIDタグ 3の RWM303に管理情報が最後に記録された時刻を表 している。次に、ステップ S225において、制御部 301は、通信部 304に記録時刻 Tb を送信するように指示し、通信部 304は、記録時刻 Tbを情報記録再生装置 2へ送信 する。 [0150] 次に、ステップ S205において、情報記録再生装置 2の通信部 22は、記録時刻 Tb を受信して制御部 20へ出力する。次に、ステップ S206において、制御部 20は、記 録時刻 Taと記録時刻 Tbとを比較し、記録時刻 Taが記録時刻 Tbより早いか否かを判 断する。ここで、記録時刻 Taが記録時刻 Tbより遅いと判断された場合 (ステップ S20 6で NO)、ステップ S207において、制御部 20は、通信部 22に管理情報送信要求を 送信するように指示し、通信部 22は、管理情報送信要求を RFIDタグ 3へ送信する。 なお、記録時刻 Taと記録時刻 Tbとが同じ時刻である場合、ステップ S207の処理へ 移行する。 Next, in step S 223, the communication unit 304 of the RFID tag 3 receives the recording time transmission request and outputs the request to the control unit 301. Next, in step S224, the control unit 301 reads the recording time Tb stored in the R WM 303. Note that the recording time Tb in the present embodiment represents the time when management information was last recorded in the RWM 303 of the RFID tag 3. Next, in step S225, the control unit 301 instructs the communication unit 304 to transmit the recording time Tb, and the communication unit 304 transmits the recording time Tb to the information recording and reproducing apparatus 2. Next, in step S205, the communication unit 22 of the information recording / reproducing apparatus 2 receives the recording time Tb and outputs it to the control unit 20. Next, in step S206, the control unit 20 compares the recording time Ta with the recording time Tb, and determines whether the recording time Ta is earlier than the recording time Tb. Here, if it is determined that the recording time Ta is later than the recording time Tb (NO in step S206), the control unit 20 instructs the communication unit 22 to transmit a management information transmission request in step S207. The communication unit 22 transmits a management information transmission request to the RFID tag 3. If the recording time Ta and the recording time Tb are the same time, the process proceeds to step S207.
[0151] 次に、ステップ S226において、 RFIDタグ 3の通信部 304は、管理情報送信要求を 受信して制御部 301へ出力する。次に、ステップ S227において、制御部 301は、 R WM303に記憶されている管理情報を読み出す。次に、ステップ S228において、制 御部 301は、通信部 304に管理情報を送信するように指示し、通信部 304は、管理 情報を情報記録再生装置 2へ送信する。  Next, in step S226, the communication unit 304 of the RFID tag 3 receives the management information transmission request, and outputs the management information transmission request to the control unit 301. Next, in step S227, the control unit 301 reads out the management information stored in the R WM 303. Next, in step S 228, the control unit 301 instructs the communication unit 304 to transmit the management information, and the communication unit 304 transmits the management information to the information recording / reproducing apparatus 2.
[0152] 次に、ステップ S208において、情報記録再生装置 2の通信部 22は、管理情報を 受信して制御部 20へ出力する。次に、ステップ S209において、制御部 20は、記録 及び再生インターフェース部 14を介して可換記録媒体記録部 15を制御し、光デイス ク ODへ管理情報を書き込む。  Next, in step S208, the communication unit 22 of the information recording / reproducing apparatus 2 receives the management information and outputs the management information to the control unit 20. Next, in step S209, the control unit 20 controls the removable recording medium recording unit 15 via the recording and reproduction interface unit 14 to write management information to the optical disk OD.
[0153] ステップ S209で管理情報が光ディスク ODへ書き込まれた後、又は、ステップ S20 6で記録時刻 Taが記録時刻 Tbより早 、と判断された場合 (ステップ S206で YES)、 ステップ S210において、制御部 20は、記録及び再生インターフェース部 14を制御 し、光ディスク ODに記録されている管理情報を読み出す。次に、ステップ S211にお いて、制御部 20は、記録及び再生インターフェース部 14を制御し、管理情報を用い て光ディスク ODに記録されているコンテンツの記録又は再生を行う。  After the management information is written to the optical disc OD in step S209, or when it is determined that the recording time Ta is earlier than the recording time Tb in step S206 (YES in step S206), control is performed in step S210. The unit 20 controls the recording and reproducing interface unit 14 to read out management information recorded on the optical disc OD. Next, in step S211, the control unit 20 controls the recording and reproduction interface unit 14 to record or reproduce the content recorded on the optical disc OD using the management information.
[0154] このように、最後に管理情報が光ディスク ODに記録された時刻 Taが光ディスク OD 力も読み出されるとともに、最後に管理情報が RFIDタグ 3に書き込まれた時刻 Tbが RFIDタグ 3から読み出される。そして、光ディスク ODカゝら読み出された時刻 Taと、 R FIDタグ 3から読み出された時刻 Tbとが比較される。ここで、光ディスク OD力も読み 出された時刻 Taが RFIDタグ 3から読み出された時刻 Tbよりも遅いと判断された場合 、光ディスク OD力 管理情報が読み出される。一方、光ディスク OD力 読み出され た時刻 Taが RFIDタグ 3から読み出された時刻 Tbよりも早 、と判断された場合、 RFI Dタグ 3から管理情報が読み出される。 As described above, the time Ta at which the management information was last recorded in the optical disc OD is read out as well as the optical disc OD, and the time Tb at which the management information is finally written in the RFID tag 3 is read out from the RFID tag 3. Then, the time Ta read out from the optical disc OD is compared with the time Tb read out from the R FID tag 3. Here, when it is determined that the time Ta at which the optical disk OD power is also read out is later than the time Tb at which it is read from the RFID tag 3 , Optical disc OD power management information is read out. On the other hand, when it is determined that the time Ta at which the optical disk OD power is read is earlier than the time Tb at which it is read from the RFID tag 3, management information is read from the RFID tag 3.
[0155] したがって、光ディスク ODに記録されている管理情報と、 RFIDタグ 3に記憶されて いる管理情報とのうちの最新の管理情報が読み出されるので、最新の管理情報を用 いてコンテンツデータを再生することができる。例えば、管理情報を RFIDタグ 3に書 き込む機能を備えない情報記録再生装置によって、管理情報が光ディスクに記録さ れた場合、 RFIDタグ 3に記憶されて ヽる管理情報よりも光ディスクに記録されて!ヽる 管理情報の方が新 、情報であるので、この最新の管理情報を用いてコンテンツデ ータを再生することができる。 Accordingly, since the latest management information of the management information recorded in the optical disc OD and the management information stored in the RFID tag 3 is read, the content data is reproduced using the latest management information. can do. For example, when the management information is recorded on the optical disc by the information recording / reproducing apparatus which does not have the function of writing the management information in the RFID tag 3, the management information stored in the RFID tag 3 is recorded on the optical disc rather than the management information. The management information is newer and more information, so content data can be played back using this latest management information.
[0156] なお、本実施の形態では、光ディスク ODに記録されて 、る管理情報と、 RFIDタグ 3に記憶されている管理情報とのうちの最新の管理情報を読み出すとしているが、本 発明は特にこれに限定されず、光ディスク ODに記録されている管理情報の一部と、 RFIDタグ 3に記憶されている管理情報の一部とのうちの最新の管理情報の一部を 読み出してもよい。また、管理情報だけでなぐアクセス履歴情報、コンテンツ再生履 歴情報及び起動情報などを記録時刻に応じて光ディスク OD及び RFIDタグ 3の 、ず れか一方から読み出してもよ!/、。  In the present embodiment, the latest management information out of the management information recorded in the optical disc OD and the management information stored in the RFID tag 3 is read out, but the present invention In particular, the present invention is not limited to this, and a part of the latest management information may be read out of a part of the management information recorded in the optical disc OD and a part of the management information stored in the RFID tag 3 . In addition, it is possible to read out access history information, content reproduction history information, activation information, etc. that are not only management information, from the optical disc OD or the RFID tag 3 depending on the recording time.
[0157] 管理情報を記録する前に電源がシャットダウンした場合、再起動後のデータの復旧 が困難である。そこで、本実施の形態では、 RFIDタグ 3に記録するためのバックアツ プ電源を別途設け、メイン電源がシャットダウンした場合であっても、ノックアップ電源 に切り替え、 RFIDタグ 3に管理情報を記録してもよい。図 15は、本発明の変形例に おける情報記録再生装置 2の内部構成を示すブロック図である。  If the power is shut down before the management information is recorded, it is difficult to recover data after the restart. Therefore, in the present embodiment, a backup power supply for recording on the RFID tag 3 is separately provided, and even if the main power supply is shut down, switching to the knock-up power supply is performed and management information is recorded on the RFID tag 3. It is also good. FIG. 15 is a block diagram showing an internal configuration of the information recording / reproducing apparatus 2 in the modification of the present invention.

[0159] 電源 23は、情報記録再生装置 2を構成する各部に電力を供給する。バックアップ 電源 24は、 RFIDタグ 3に情報を記録するための機能、すなわち、制御部 20、記録 及び再生インターフェース部 14、可換記録媒体記録部 15及び通信部 22を動作させ るための電力を供給する。電源切替部 25は、電源 23がシャットダウンした場合、バッ クアップ電源 24に切り替える。 The power supply 23 supplies power to each part constituting the information recording and reproducing apparatus 2. backup The power supply 24 has a function for recording information in the RFID tag 3, that is, supplies power for operating the control unit 20, the recording and reproduction interface unit 14, the exchangeable recording medium recording unit 15 and the communication unit 22. . The power supply switching unit 25 switches to the backup power supply 24 when the power supply 23 is shut down.
[0160] 本実施の形態では、電源 23が第 1の電源の一例に相当し、ノ ックアップ電源 24が 第 2の電源の一例に相当し、電源切替部 25が電源切り替え手段の一例に相当する In the present embodiment, power supply 23 corresponds to an example of a first power supply, knock-up power supply 24 corresponds to an example of a second power supply, and power switching unit 25 corresponds to an example of a power switching unit.
[0161] ここで、上記のように構成された情報記録再生装置 2の動作にっ 、て説明する。制 御部 20は、電源 23からの電力の供給状態を検知しながら、停電等の異常によって 電源 23からの電力供給が遮断されると、電源切替部 25に対して電力の供給元をバ ックアップ電源 24に切り替えるよう指示する。 Here, an operation of the information recording / reproducing apparatus 2 configured as described above will be described.
