Abstract
An optical disc drive is disclosed. The optical disc drive comprises a housing including an upper housing and a lower housing; and a herringbone pattern that is protruded toward the inner space of the housing on the inner surface of the upper housing and causes an air flow generated by the rotation of an optical disc to be switched to the direction of the optical disc. The herringbone pattern comprises at least one inflection point, and makes an acute angle at the inflection point relative to the direction of the air flow formed along the inner surface of the upper housing. Accordingly, the optical disc can be stably chucked and rotated by switching the air flow generated by the rotation of the optical disc to the direction of the optical disc.
