Non-contact communication medium, magnetic tape cartridge, non-contact communication medium operation method, and program

摘要

PROBLEM TO BE SOLVED: To fix an identifier determined by a vendor of a magnetic tape cartridge at a timing intended by the vendor of the magnetic tape cartridge, a non-contact communication medium, a magnetic tape cartridge, an operation method of the non-contact communication medium, and a program. I will provide a. A non-contact communication medium includes a processor, a memory built in or connected to the processor, and performs non-contact communication with an external communication device. The memory has a storage block in which information determined according to the specifications of the magnetic tape cartridge on which the non-contact communication medium is mounted is stored, and the storage block has an identifier storage field. The processor writes the identifier given to the non-contact communication medium from the external communication device to the identifier storage field, and locks the identifier storage field according to the specific command given to the non-contact communication medium from the external communication device. conduct.
