Abstract
A method of accessing a multifile storage medium and a library system. The library system includes recording/reproducing apparatuses for performing a recording/reproducing operation on the multifile storage medium, a plurality of recording/reproduction control units for controlling transaction of information with a host, a plurality of buffers provided between the recording/reproduction control units and the recording/reproducing apparatuses, a library control unit for controlling the whole library system, a directory for recording correspondence between the individual multifile recording media and a plurality of files stored therein, a shelf for housing the multifile storage media and handling devices. The plural buffers can be accessed independently of one another. Plural files are transferred between the buffers and the storage medium on a file-by-file basis. The access requests to the files are disposed of within the buffer.
