Title (EN) RECORDING/REPRODUCING DEVICE AND INFORMATION RECORDING MEDIUM
(FR) DISPOSITIF D'ENREGISTREMENT/REPRODUCTION ET SUPPORT D'ENREGISTREMENT D'INFORMATIONS
(JA) 記録再生装置および情報記録媒体
Abstract:
(EN) A recording/reproducing device (1) is provided with an information readout unit (121) for reading out a first information (OS or application) recorded in an optical disk (10); an information storing/controlling unit (122) for storing the first information read out by the information readout unit (121) in a storing unit (15); and an enable/disable control unit (21) which enables one first information and disables the other first information among the first information stored in the storing unit (15) by the information storing/controlling unit (122) and the first information recorded in the optical disk (10). While sufficiently ensuring the safety of the first information recorded in the optical disk (10), the first information can be used in a plurality of recording/reproducing devices.
(FR) L'invention porte sur un dispositif d'enregistrement/reproduction (1) qui comporte une unité de lecture d'informations (121) pour lire des premières informations (système d'exploitation ou application) enregistrées dans un disque optique (10); une unité de stockage/commande d'informations (122) pour stocker les premières informations lues par l'unité de lecture d'informations (121) dans une unité de stockage (15); et une unité de commande de validation/invalidation (21) qui valide des premières informations et invalide les autres premières informations parmi les premières informations stockées dans l'unité de stockage (15) par l'unité de stockage/commande d'informations (122) et les premières informations enregistrées dans le disque optique (10). Tout en assurant de manière suffisante la sécurité des premières informations enregistrées dans le disque optique (10), les premières informations peuvent être utilisées dans une pluralité de dispositifs d'enregistrement/reproduction.
(JA)  記録再生装置(1)は、光ディスク(10)に記録されている第1情報(OSやアプリケーション)を読み出す情報読み出し部(121)と、情報読み出し部(121)が読み出した第1情報を記憶部(15)に保存する情報保存制御部(122)と、光ディスク(10)が取り出されるときの、情報保存制御部(122)が記憶部(15)に保存した第1情報と、光ディスク(10)に記録されている第1情報とについて、いずれか一方の第1情報を使用可能状態とし、他方を使用不可能状態とする使用可否制御部(21)と、を備える。これにより、光ディスク(10)に記録された第1情報に対する安全性を十分に確保した上で、複数の記録再生装置にて第1情報を利用することができる。
