Magnetic tape drive, magnetic tape cartridge, and information management method

A magnetic tape drive used for a magnetic tape cartridge including a magnetic tape on which a servo pattern is recorded, and a storage medium other than the magnetic tape, in which information is capable of being stored and acquired in a non-contact manner, the magnetic tape drive comprising:

• a processor;
• and
• a magnetic head controlled by the processor,
• wherein geometrical characteristic information, which is information regarding a geometrical characteristic of the servo pattern, is stored in the storage medium,
• the geometrical characteristic information, which is stored in the storage medium, is recorded in the magnetic tape,
• the processor is configured to:
• leave second geometrical characteristic information in the storage medium by erasing first geometrical characteristic information from the geometrical characteristic information stored in the storage medium,
• the second geometrical characteristic information is geometrical characteristic information capable of specifying a recording position in the magnetic tape at which the geometrical characteristic information is recorded, of the geometrical characteristic information stored in the storage medium, and
• the first geometrical characteristic information is geometrical characteristic information other than the second geometrical characteristic information of the geometrical characteristic information stored in the storage medium.
