摘要： PROBLEM TO BE SOLVED: To make it possible to cancel a centrifugal force generated by an eccentric mass during disk rotation irrespective of the direction of placing a disk driving device, by providing inner and outer peripheral walls in a first ring rotated simultaneously with a clamper for fixing a disk and disposing a second ring between these walls via an elastic body so that it has the same center axis as that of a disk motor when rotation is stopped. SOLUTION: The second ring 7 serving as a weight for canceling a centrifugal force generated by an eccentric mass is provided between the inner and outer peripheral walls 5a and 5b of the first ring 5 fitted with the outer peripheral part of a clamper 3 to be integrally rotated. The second ring 7 is pressed by an elastic body 9 so that a rotational center axis is concentric with that of the spindle 2a of a disk motor 2 when the rotation of disk 6 is stopped. Thus, the centrifugal force generated by the eccentric mass is applied in a direction for being canceled by a centrifugal force generated in the second ring 7, and the centrifugal force generated by the eccentric mass is reduced and completely canceled.

摘要： PURPOSE:To provide the magneto-optical recording and reproducing device which can protect a magnetic head from an operator's inadvertent contact. CONSTITUTION:A cartridge holder 21 for holding a cartridge is provided turnably around a holder turning shaft 22a and a magnetic head arm 12 for holding the magnetic head 11 is provided turnably around an arm turning shaft 13. The holder turning shaft 22a and the arm turning shaft 13 are non-coaxially disposed so that the magnetic head 11 is housed between the cartridge holder 21 and a cover 31 and is deviated from an aperture for the magnetic head when the cover 31 is opened. Thus, the magnetic head is housed to the rear side of the cartridge holder when the cover is opened and, therefore, the magnetic head is protected from the operator's inadvertent contact and the position deviation and failure of the magnetic head are prevented.
