摘要:
An information reproducing apparatus is provided with: a clamping device (900) capable of clamping and clamp-releasing a recording medium (100); a rotating device (20) for rotating the recording medium clamped by the clamping device; a reading device (30) disposed opposite to an information record surface of the recording medium for reading information recorded on the information record surface of the recording medium; a driving device (34, 34D, 32) capable of moving the reading device in a radial direction of the recording medium; and a linkage device (24, 83, 85) for linking a clamping or clamp-releasing action by the clamping device with a movement of the reading device by the driving device. The driving device moves the reading device as a first driving voltage is supplied to the driving device upon reading the information recorded on the information record surface, the first driving voltage including such a value that the action of the clamping device is not linked with the movement of the reading device by the linkage device.
