A recording and reproducing method executed by a recording and reproducing device, the method comprising:

• reading production information from a recording medium of a magnetic tape cartridge, the magnetic tape cartridge including a magnetic tape, and the recording medium other than the magnetic tape and on which the production information is recorded, the production information being information regarding the magnetic tape obtained in a production process of the magnetic tape cartridge;
• and
• performing an initialization process of the magnetic tape cartridge by recording the production information on the magnetic tape and invalidating the production information in the recording medium, the initialization process being performed at a time when the magnetic tape cartridge is initially loaded into the recording and reproducing device, after the magnetic tape cartridge has been shipped or after the magnetic tape cartridge has been formatted.

A non-transitory storage medium storing a program that causes a recording and reproducing device to perform recording and reproducing processing, the recording and reproducing processing comprising:

• reading production information from a recording medium of a magnetic tape cartridge, the magnetic tape cartridge including a magnetic tape, and the recording medium other than the magnetic tape and on which the production information is recorded, the production information being information regarding the magnetic tape obtained in a production process of the magnetic tape cartridge;
• and
• performing an initialization process of the magnetic tape cartridge by recording the production information on the magnetic tape and invalidating the production information in the recording medium, the initialization process being performed at a time when the magnetic tape cartridge is initially loaded into the recording and reproducing device, after the magnetic tape cartridge has been shipped or after the magnetic tape cartridge has been formatted.
