A magnetic tape cartridge including: a magnetic tape; and a recording medium including a predetermined area for recording defect information, which is information regarding a defect of the magnetic tape detected in a production process of the magnetic tape.

A method for manufacturing a reel includes molding a reel configuration component that is made of resin and includes a reel hub with an outer peripheral face for winding a recording tape onto, after the molding and prior to the reel configuration component cooling and shrinking, embedding a reinforcement ring into the reel hub, and after the embedding, cooling and shrinking the reel configuration component and fixing the reinforcement ring to the reel hub.

A method of manufacturing magnetic tape storage data cartridges may include cutting a master tape having a first width into multiple tape sections that each have a smaller width than the first width, cleaning the tape sections to remove debris caused by the cutting, and writing the servo tracks on each tape section after the tape section is cleaned. The method may further include spooling each tape section into a respective tape cartridge after writing the servo track on the tape section.

A tape cartridge according to an embodiment of the present technology includes: a first tape reel; a magnetic tape; a leader pin; and a second tape reel. The magnetic tape is wound around the first tape reel. The leader pin is attached to an end portion of the magnetic tape and includes a shaft portion parallel to a tape width direction. The second tape reel includes a cylindrical reel hub, a first flange, and a second flange. The reel hub has an inner peripheral surface and an outer peripheral surface, a housing unit capable of housing the leader pin being provided on the inner peripheral surface or the outer peripheral surface. The first flange is provided to one end portion of the reel hub. The second flange is provided to the other end portion of the reel hub and includes a slit portion through which the magnetic tape is capable of passing.
