An optical disc apparatus comprises the followings within housing thereof: an optical pickup, which is configured to conduct recording or reproducing of a disc, as an information recording medium; a rotation mechanism of said disc; a transfer mechanism, which is configured to move said optical pickup from an inner periphery of said disc up to an outer periphery thereof; a mechanical chassis, which is configured to mount said optical pickup, said disc rotation mechanism and said transfer mechanism thereon; a disc tray, which is configured to conduct storing and taking out of said disc; and a connector, which is configured to electrically connect between a circuit board for conducting driving control of said rotation mechanism and an external electronic apparatus, wherein a projection portion is provided on a reverse surface of said disc tray, at a portion facing to said connector at a position when said disc tray is stored, to be inserted into a gap between periphery of said connector and said housing, and thereby preventing fluid sounds (or wind sounds) generating due to high-speed rotation of the disc when high-speed recording/reproducing, from leaking into an outside of the apparatus, so as to reduce the noises therefrom.
