ABSTRACT:
Apparatus and method for protecting the read/write lens of a magneto-optic drive apparatus using a tongue that covers the read/write lens during the opening and closing of the shutter on a cartridge as it is inserted into and as it is removed from the magneto-optic drive apparatus and during the period that the read/write lens is in a parked position. Apparatus also protects the turning lens and splitting lens and other optical components during insertion and removal of a cartridge and also when these components are in a parked position. The flow of cooling air is also controlled to prevent introduction of dust to the read/write lens and other optical components.
