Optical information storage apparatus and optical information storage system

The object of the present invention is to provide an optical information storage apparatus and an optical information storage system with a mass-storage capacity in which adhesion of dust to an optical storage medium or an objective lens is suppressed. According to the present invention, a system housing contains an optical information storage apparatus that includes: an inflow section into which air flows from outside a blade housing integrally retaining a media storing section, a medium moving section and a recording/reproducing section; and an outflow section from which the air flowing into the inflow section flows out to outside the blade housing. The system housing also contains a blower that sends air to the inflow section.
