Optical disk drive having a carrying roller that contacts a surface of an optical disk

An optical disk drive comprising

• a carrying roller configured to carry an optical disk in a first direction;
• the carrying roller including a first roller portion and a second roller portion which are aligned in a second direction along the optical disk and orthogonal to the first direction and which are so disposed as to make contact with a surface on one side of the optical disk;
• an axis of the first roller portion being so inclined that a distance between the axis of the first roller portion and the one-side surface of the optical disk gradually increases from an end portion on one side of the carrying roller in the second direction toward a central portion of the carrying roller in the second direction;
• an axis of the second roller portion being so inclined that a distance between the axis of the second roller portion and the one-side surface of the optical disk gradually increases from an end portion on the other side of the carrying roller in the second direction toward the central portion of the carrying roller in the second direction.
