Abstract: A tape reel having an improved reliability during high−speed transport of the magnetic tape by improving the molding quality of the flange portion of the tape reel and a tape cartridge having this are disclosed. Reference faces (152v) are provided between a chucking gear (152b) and an outer circumferential rib (152r2) outside the chucking gear (152b), independently of the outer circumferential rib (152r2). Each of the reference faces (152v) is composed two faces: a first rib (152v1) extending circumferentially and a second rib (152v2) extending perpendicularly to the first rib (152v1). The volume of the portions forming the reference faces (152v) is small, and consequently the sink marks after the resin is cured are suppressed, the molding quality of the flange portion (152) is improved. Consequently, the straight−ahead transportability of the magnetic tape during high−speed transport and the reliability of recording/reproduction are both improved.

Abstract: A tape reel allowing the reliability of a magnetic tape running at a high speed to increase and a tape cartridge having the tape reel, the tape reel wherein an annular chucking gear 152b formed at the lower surface center part of the lower side flange part 152 of the tape reel 150 is formed of vertical wall surfaces to suppress the idle rotation and rise of the tape reel, whereby the running stability and straight forward running capability of the magnetic tape when the tape reel 150 is rotated at a high speed can be assured, and the reliability of the tape cartridge in high speed operation can be increased.
