Recording and reproducing device with medium regulating portion

A recording and reproducing device comprising:

• a case;
• a plurality of recording mediums having a disk-shape, a motor configured to rotate the plurality of recording mediums, a head configured to read or write information from or to a corresponding one of the plurality of recording mediums, and an actuator configured to drive the head to scan in a radial direction of the corresponding one of the plurality of recording mediums which are provided in the case;
• and
• a regulating portion configured to, when an external shock is applied to the plurality of recording mediums, contact an outer peripheral edge of each of the plurality of recording mediums to regulate displacements of each of the plurality of recording mediums due to bending of each of the plurality of recording mediums,
• wherein the regulating portion includes a plurality of regulating members which are movable in an axial direction parallel to a rotation axis of the plurality of recording mediums,
• each of the plurality of regulating members is arranged in the axial direction so as to be associated with each of the plurality of recording mediums arranged in the axial direction, and
• the plurality of regulating members are provided to be rotatable independently of each other around an axis parallel to the rotation axis.
