记录再现装置和记录介质
摘要：
本发明提供一种记载再现装置，其对记录介质进行照射，从而进行信息的记录或再现，该记录再现装置包括：使上述记录介质旋转的介质旋转部；具有能够在规定的面内移动的可动部的移动部；使用在上述记录介质设置的角度检测用标记检测上述记录介质的旋转角度的旋转角度检测部；使用在上述记录介质设置的偏心检测用标记检测上述记录介质的位置的位置检测部；和将上述旋转角度检测部和上述位置检测部固定的部件，上述可动部在与上述记录介质的记录面大致平行的平面内相对于上述部件相对地移动，上述介质旋转部固定于上述可动部。
摘要（英）：

This recording/reproducing apparatus that records or reproduces information by radiating light to a recording medium is provided with: a medium rotating unit that rotates the recording medium; a moving unit having a movable unit that is capable of moving within a predetermined plane; a rotation angle detecting unit that detects a rotating angle of the recording medium using an angle detection mark that is provided on the recording medium; a position detecting unit that detects a position of the recording medium using an eccentricity detection mark that is provided on the recording medium; and a member for fixing the rotation angle detecting unit and the position detecting unit. With respect to the member, the movable unit relatively moves within a plane substantially parallel to the recording surface of the recording medium, and the medium rotating unit is fixed to the movable unit.
