    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 translation: 公开了一种通过提高带盘的凸缘部分的成型质量和具有这种带盘的带盒来提高磁带高速传输期间可靠性的磁带卷盘。 参考面(152v)独立于外周肋(152r2)设置在夹紧齿轮(152b)和夹紧齿轮(152b)外部的外周肋(152r2)之间。 每个参考面(152v)由两个面构成:沿圆周方向延伸的第一肋(152v1)和垂直于第一肋(152v1)延伸的第二肋(152v2)。 形成基准面(152v)的部分的体积小,因此抑制了树脂固化后的凹痕,凸轮部(152)的成型品质提高。 因此,高速运送期间的磁带的直线可移动性和记录/再现的可靠性均得到改善。
