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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
