Abstract: A recording control device, a recording control method, and a recording tape cartridge capable of estimating a lifetime of the recording tape cartridge are obtained. A recording control device reads information correlated with an error rate of reading or writing of data from or to a magnetic tape included in a recording tape cartridge, the information being recorded on a RFID tag included in the recording tape cartridge, and a measurement date of the information, and estimates a lifetime of the recording tape cartridge using the read information and the read measurement date, and the information measured at the time of using the recording tape cartridge and a measurement date.

Abstract: A tape is prevented from moving in a width direction and the tape is prevented from being damaged in a state in which the tape is wound around a tape reel. There is provided a tape reel including: a cylindrical portion around which a tape is wound; a first flange annularly projecting toward an outer side in a radial direction of the cylindrical portion from the cylindrical portion; and a second flange separated from the first flange in an axial direction of the cylindrical portion and annularly projecting toward the outer side in the radial direction from the cylindrical portion, in which a distance between the first flange and the second flange becomes narrower while extending toward the outer side in the radial direction, and a bending elastic modulus of the first flange is smaller than a bending elastic modulus of the second flange.
