A disc tray of an optical disc drive includes a tray body having a seating surface on which an optical disc is to be seated. The tray body is installed in the optical disc drive to slide in and out of the optical disc drive. The disc tray also includes a window bored through the disc tray so that an optical pickup to record or read data accesses the optical disc, and a vortex restraint unit which spatially restrains a vortex generated by a rotation of the optical disc.
