What kind of archiving medium is used for MetaArchive?
MetaArchive uses magneto-optical (MO) disks for the storage of archived data. Therefore each Ikaros or Isis system, that acts as data server, is equipped with a MO disk drive. MO disks are known to be the most secure data storage medium available. They provide full read and write access and are therefore easy to handle. Today a MO disk has a capacity of up to 2.3 GB.
