Abstract
A method is provided for restricted update sharing of removable media in a media library. Media is allowed to be retrieved from storage slots of a media library and moved to a drive in a restricted update mode. The media includes short term attributes that include short term media data structures, and long term attributes. A file system includes short term memory and long term memory associated with the media. Updates to the long term attributes and long term memory are restricted. Updates to the short term attributes and the short term memory are allowed. The short term memory of the file system is refreshed each time the media is moved to the drive, which includes changing data in the short term memory back to an original state and rebuilding the data in the short term memory from the media data structures of the short term attributes.
