An optical disc drive comprising at least a housing, an optical disc cassette, a cassette ejector and a fixing element is provided. The housing has an ejection opening. The cassette ejector and the fixing element are disposed in the housing. The optical disc cassette is disposed inside the housing for holding a plurality of optical discs. The housing has an open fixing groove. The fixing element lodges on the open fixing groove when the optical disc cassette is pushed into the housing. When the optical disc cassette is manually ejected, a manual ejection element that passes through the ejection opening is used to change the relative position between the fixing element and the open fixing groove. Consequently, the optical disc cassette can be ejected from the housing by the cassette ejector.
