Abstract: The present invention relates to a communication system and communication method which enable various types of near field communication, and a data processing apparatus. NFC communication apparatuses 1 to 3 have two features in that each can perform communication in two communication modes and that each can perform data transmission at a plurality of transfer rates. The two communication modes consist of a passive mode and an active mode. In the passive mode, between the NFC communication apparatuses 1 and 2, for example, the NFC communication apparatus 1 transmits data to the NFC communication apparatus 2 by modulating electromagnetic waves generated by itself, while the NFC communication apparatus 2 transmits data to the NFC communication apparatus 1 by performing load modulation on the electromagnetic waves generated by the NFC communication apparatus 1. Alternatively, in the active mode, either of the NFC communication apparatuses 1 and 2 transmits data by modulating electromagnetic waves generated by itself. The present invention can be applied to, for example, an IC card system, etc.

Abstract: This invention provides a recording medium supportable device such as a library device (50), which authenticates each recording medium by identification information such as serial number and controls the recording medium by a command based on radio communication. In this case, a communication identifier like a session identifier corresponding to the identification number is set and provided and the communication identifier is included in a command at the time of execution of control, so that only a specified recording medium to be controlled carries out an operation corresponding to the command. When authenticating the recording medium, the identification information, which is proper information such as serial number, is confirmed through reliable communication using successive communication identifiers, and reliable authentication of the recording medium is carried out by several stages of communication.

Abstract: A communication apparatus and a communication method prevent responses from being simultaneously received from two or more communicating parties. A first NFC apparatus transmits data for requesting IDs, and acquires IDs sent from second and third NFC apparatuses in reply to the request. After acquiring the IDs of the second and third NFC apparatuses, the first NFC apparatus transmits data that includes their IDs as the data for the second and third NFC apparatuses. If the first NFC apparatus cannot properly acquire the IDs of the second and third NFC apparatuses, then it sends the data for requesting their IDs again. Upon receipt of the request for the IDs, the second and third NFC apparatuses generate their own IDs by using random numbers and send the generated IDs. If the second and third NFC apparatuses receive the request for their IDs again, then they re-generate their own IDs by using random numbers, and send the re-generated IDs again. The present invention can be applied to, for example, an IC card system.

Abstract: The present invention relates to a communication system, a communication device, and a communication method for easily solving a problem of a hidden terminal. Communication devices 1 and 3 determine whether or not an electromagnetic wave at the level of a magnetic-flux density TH1 or more for determining the suppression of the output of carrier. When the electromagnetic wave at the level of the magnetic-flux density TH1 or more for determining the suppression of the output of the carrier is not detected, the communication devices 1 and 3 start the output of the electromagnetic wave. A communication device 2 needs the electromagnetic wave at the level of a magnetic-flux density TH2 or more of the carrier at an operating limit, which is higher than the magnetic-flux density TH1 for determining suppression of the output of carrier so as to obtain data via the electromagnetic wave. The present invention is applied to, e.g., an IC (Integrated Circuit) card system.

Abstract: A recording and reproducing apparatus uses a cassette including a recording medium such as tape (3) and which has a write-protect mode. The recording/reproducing means has a head (11, 12, 13) for recording data inputted to the apparatus on the recording medium (3) and/or reproducing data recorded on the recording medium (3); a detecting means (26) for detecting whether the cassette is set to a record-possible mode or a write-protect mode; and a control means (4, 15) for controlling the recording/reproducing means. The control means allows input data and attribute information of the recording medium to be recorded when the cassette is set to the record-possible mode and allows the attribute information but not the input data to be recorded when the cassette is set to the write-protect mode.
