Cartridge

A cartridge comprising:

• a tape-shaped magnetic recording medium;
• and
• a cartridge memory, wherein
• the cartridge memory comprises
• a communication unit that communicates with a recording/reproducing device in a state where the cartridge is loaded on the recording/reproducing device;
• a storage unit;
• and
• a control unit that stores information received from the recording/reproducing device through the communication unit in the storage unit, reads the information from the storage unit according to a request from the recording/reproducing device, and transmits the information to the recording/reproducing device through the communication unit,
• wherein the information includes manufacturing information of the cartridge and adjustment information for adjusting a tension applied to the tape-shaped magnetic recording medium in a longitudinal direction thereof of the tape-shaped magnetic recording medium, and
• wherein the tape-shaped magnetic recording medium has a plurality of servo bands, and
• wherein an elastic limit value σMD of the tape-shaped-magnetic recording medium in the longitudinal direction of the tape-shaped magnetic recording medium satisfies 0.8 [N]≤σMD.
