Patent number: 7289292Abstract: The invention relates to a library apparatus for use in storage, recording or reproduction of recording media, and its object is to effect a cleaning process on recording media within the apparatus. Another object is to prevent contamination of a recording/reproduction unit through cleaning process of recording media. The apparatus is arranged such that it comprises an enclosure; a recording/reproduction unit disposed in the enclosure and recording data onto a recording medium or reproducing data from the recording medium; and a cleaning unit disposed in the enclosure and cleaning the recording medium ejected from the recording/reproduction unit. The recording medium ejected from the recording/reproduction unit in response to a data check error, etc., is carried for cleaning to the cleaning unit disposed together with the recording/reproduction units in the same enclosure.Type: GrantFiled: September 16, 2004Date of Patent: October 30, 2007Assignee: Fujitsu LimitedInventors: Yoshio Kotaki, Yukio Katsuyama
