Abstract
A drive unit for use in an optical memory unit has a front panel, a drive mechanism, and sealing members. The front panel has an air vent and a slot for allowing passage of a cassette case containing a disk-shaped recording medium. The drive mechanism loads the cassette case through the slot and drive the recording medium in a specified direction in order to record and reproduce information on and from the recording medium. The sealing members seals the drive mechanism nearly completely, in order to prevent migration of the outside air into the drive mechanism as the air is introduced via the air vent.
