The present application discloses optical disc apparatus including: drive mechanism for rotating medium including processing surface to be subjected optical information process; housing for storing drive mechanism; tray mechanism for displacing medium between storage position, at which medium is stored in housing, and ejection position, at which medium is ejected from housing; at least one objective lens for condensing light onto processing surface of medium situated at storage position to perform information process; and first displacement mechanism for displacing at least one objective lens along processing surface between first position and second position which is more distant from rotational center of medium rotated by the drive mechanism than first position is. Tray mechanism defines at least one opening in position closer to second position than first position.
An optical disc apparatus, comprising:
A sheet member mounted on a tray plate to be displaced between a storage position, at which a medium to be subjected to optical information process is stored in a housing, and an ejection position, at which the medium is ejected from the housing, wherein
A cleaning method for an objective lens, the method comprising steps of:
