Fixing mechanism for recording medium

摘要

A recording medium mounted on the rotary body in a recording medium drive. First and second fixing members sandwiches the recording medium around the rotary body. An elastic member is interposed at least between the first fixing member and the recording medium. The elastic member serves to enhance the friction between the first fixing member and the recording medium in the fixing mechanism. Even if an impact is applied to the recording medium, the recording medium is thus reliably prevented from shifting within a plane perpendicular to the central axis of the rotary body, namely from a lateral shift.
