The invention discloses a high-precision rotating angle error calibration graduated disk with recognition graduated lines and a rotating angle error calibration system. The rotating angle error calibration graduated disk includes a disk body that is a cylinder body and has the entire side surface being a reflective surface; an encoded graduated line group that includes several circles of encoded graduated lines scribed on the reflective surface and is binary encoded; and a reference graduated line group which includes a plurality of reference graduated lines with equal spacing and equal widththat are scribed on the reflective surface. The invention provides the high-precision rotating angle error calibration graduated disk with recognition graduated lines, which can realize the rotating angle error calibration of higher resolution and accuracy than a conventional rotating angle error calibration device when used in conjunction with an angle recognition device. 本发明公开了种具有识别刻线的高精度转角误差标定刻盘及转角误差标定系统。所述转角误差标定刻盘包括：盘
