Claims22
A cover for an optical disc drive, the cover comprising:
- a body comprising a top portion that is configured to cover a disc in response to the disc being inserted into the optical disc drive;
- and
- a pressure structure that is formed on the body,
- wherein a cross section of the pressure structure at a plane which intersects a center portion of the disc and is perpendicular to a side portion of the cover is asymmetrical about a line which intersects the center portion of the disc and is parallel to the side portion of the cover.
