    摘要： The tape reel includes the cylindrical portion and a bottom portion having an installation surface on which the cylindrical portion is installed upright. The installation surface has a central surface located on a center side of the bottom portion, and a first inclined surface formed on an outer peripheral portion of the central surface along a peripheral direction of the cylindrical portion and inclined such that a wall thickness of the bottom portion gradually decreases toward an outer peripheral side. A through hole penetrating the bottom portion is formed in the outer peripheral portion, a pair of wall portions are installed upright on the first inclined surface on both sides of the through hole in the peripheral direction, and a second inclined surface having an inclination angle smaller than an inclination angle of the first inclined surface with respect to the central surface is formed on a surface of each of the wall portions, which is connected to the central surface.

    摘要： A noncontact communication medium includes a processor, and a memory incorporated in or connected to the processor, and performs noncontact communication with an external communication device. The memory has a storage block where information regarding an attribute of the noncontact communication medium is stored and that includes a plurality of storage fields. The plurality of storage fields include a specification-independent storage field where information independent of a specification of a magnetic tape cartridge, in which the noncontact communication medium is mounted, is stored. The processor is configured to write accompanying information regarding the magnetic tape cartridge in the specification-independent storage field in response to an instruction given from the external communication device to the noncontact communication medium by the noncontact communication.

    摘要： A tape reel according to an embodiment of the present technology includes: a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub. The reel hub is formed of a material in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.3 mm or less and a water absorption rate is 0.1% or less.

    摘要： Provided is a recording tape cartridge including: a case that accommodates a reel on which a recording tape is wound and includes a reference surface that serves as a reference in an axial direction of the reel in a case where the case is loaded into a drive device; a noncontact communication medium on which individual information is recorded, the noncontact communication medium being accommodated in the case and having a plate shape; a supporting portion that is formed in the case and supports one surface of the noncontact communication medium except for a lower end portion such that the noncontact communication medium is disposed while being inclined with respect to the reference surface at an angle of approximately 45 degrees; and a groove portion that is formed in the case and accommodates a portion of the lower end portion of the noncontact communication medium. The one surface of the lower end portion of the noncontact communication medium is not in contact with the case.
