A drive unit for an optical memory device includes a casing having an insertion slot which is formed in a front section and through which a medium cartridge is inserted into an interior of the casing. A front cover member movably covers the insertion slot of the casing, and includes first and second covers which are rotatable around respective first and second rotation shafts. The first front cover has a distal end which is situated on an outer side of the casing when the insertion slot is closed, the second front cover has a distal end which is situated on an inner side of the casing when the insertion slot is closed, and the second front cover is rotated with a radius of rotation which differs from that of said first front cover.
