摘要:
A recording medium handling apparatus, such as a library apparatus, is designed to be able to carry out excellent information communication with a specific recording medium having a noncontact type memory. The recording medium handling apparatus includes a magazine for housing a plurality of tape cassettes arranged side by side, and an interface circuit capable of executing data transmission with respect to the memory in the tape cassette in a noncontact manner by executing wireless communication with a remote memory chip in the tape cassette through an antenna. The shape and the size of the antenna are set according to an interval of the tape cassettes such that when the antenna is put in a positional state where the antenna confronts an objective tape cassette having a memory with which communication is to be executed, among the plurality of tape cassettes arranged in the magazine so that communication becomes possible, a memory of a tape cassette arranged adjacently to the objective tape cassette is located at a position corresponding to a dead zone of the antenna.

摘要:
A communication apparatus includes a short-range communication unit that receives an inquiry signal from a short-range external communication apparatus and transmits a response signal in response to the inquiry signal. The communication apparatus also includes a long-range communication unit that communicates in a range wider than a communication area of the short-range communication unit. Further, the communication apparatus includes a session key generation unit that generates a session key, and an encrypting unit that encrypts the session key. The communication apparatus uses an encryption key transmitted from an external communication apparatus to encrypt the session key into an encrypted session key, transmits the encrypted session key to the external communication apparatus, and receives from the external communication apparatus a request signal to request a long-range communication, with the session key, by the long-range communication unit by using the short-range communication unit.

A communication apparatus includes a short-range communication unit and a long-range communication unit that communicates via electromagnetic waves in a range wider than a communication area of the short-range communication unit. The communication apparatus further includes a session key generating unit that generates a random number and uses the random number to generate a session key. In addition, the communication apparatus includes an encrypting unit that encrypts the session key. The communication apparatus uses an encryption key transmitted from an external communication apparatus to encrypt the session key into an encrypted session key, transmits the encrypted session key to the external communication apparatus, and receives from the external communication apparatus a communication switching request signal to request a switching from a short-range communication by the short-range communication unit to a long-range communication, with the session key, the long-range communication unit.
