Recording medium control method and recording medium adapter
First Claim
1. A recording medium controlling method which is carried out by a recording medium supportable device having interface means capable of, with respect to a recording medium having memory means for storing identification information proper to the recording medium and communication means for executing non-contact data transfer with respect to the memory means, non-contact data transfer to/from the memory means by enabling execution of radio communication to/from the communication means, the method comprising:
- an authentication step of sequentially communicating with the recording medium by using successive communication identifiers, thus confirming the identification information stored in the memory means of the recording medium and authenticating the recording medium;
a communication identifier provision step of setting a communication identifier for the recording medium authenticated at the authentication step and providing the communication identifier for the memory means of the recording medium; and
a control step of specifying the recording medium by a command including the communication identifier and carrying out operation control of the memory means of the recording medium.

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.

6. A recording medium supportable device which supports a recording medium having memory means for storing identification information proper to the recording medium and communication means for carrying out non-contact data transfer with respect to the memory means, the device comprising:
-
interface means capable of carrying out non-contact data transfer to/from the memory means by executing radio communication to/from the communication means;
authentication means for causing the interface means to execute communication with the recording medium by using successive communication identifiers, thus confirming the identification information stored in the memory means of the recording medium and authenticating the recording medium;
communication identifier setting means for a communication identifier for the recording medium authenticated by the authentication means and causing the interface means to write the communication identifier to the memory means of the recording medium; and
control means for specifying the recording medium by causing the interface means to output a command including the communication identifier, and carrying out operation control of the memory means of the recording medium. - View Dependent Claims (7, 8, 9, 10)
