Abstract: [Object] To provide a recording medium that is strong in deformation, easy to handle, excellent in portability, and inexpensive, and a recording-medium driving device thereof. [Solving Means] When an end of a recording medium 10A inserted in an insertion hole 22 of the mounting portion 20, is screwed, a recording surface of the recording medium 10A (an outer peripheral surface of an outer cylindrical member 11) opposing a pickup 30A is moved in a peripheral direction. Therefore, data recorded on the recording medium 10A can be read out by the pickup 30A. The pickup 30 is only secured to a position opposing the recording surface of the recording medium 10, so that means for moving the pickup is not required. Therefore, an inexpensive recording-medium driving device having a simple structure can be provided.
