Abstract
A storage apparatus includes a disk-shaped recording medium, a motor configured to drive and rotate the recording medium, a head configured to read information from and write information to the recording medium, and a support member configured to support the recording medium when the recording bends in response to external vibration or shock. The support member supports the recording medium by making contact with the recording medium only when the external vibration or shock is applied to the storage apparatus.
Claims14
A storage apparatus comprising:
- a disk-shaped recording medium;
- a casing accommodating the recording medium;
- a motor configured to drive and rotate the recording medium;
- a head configured to read information from and write information to the recording medium;
- a stationary support member configured to support the recording medium by making contact with the recording medium only when the recording medium bends;
- a ramp mechanism configured to move the head from a position above the recording medium to a head receded position not overlapping the recording medium in the plan view of the storage apparatus;
- and
- a flow straightening plate configured to straighten an air flow generated due to rotation of the recording medium,
- wherein the support member is attached to an inside wall of the casing, at an outer end portion of the recording medium and partially overlaps the recording medium in a plan view of the storage apparatus,
- wherein the support member has a structure that enables the support member to function as both the ramp mechanism and the flow straightening plate, and
- wherein the support member is provided at three or more locations inside the storage apparatus.
