Abstract
A tray-type optical disc drive including an optical disc drive body, a tray, a first ventilation portion and a second ventilation portion is provided. The tray movable in and out of the optical disc drive body includes a side wall and a loader. The loader adjoins the side wall. The loader further has a disc-loading region for receiving an optical disc. The first ventilation portion is disposed on the side wall, and the second ventilation portion is disposed on the loader. The airflow generated when the optical disc rotates passes through the first ventilation portion and the second ventilation portion so as to reduce the noises of the optical disc drive.
