摘要： Hard disk drive unit with buffer and cue data areas efficiently records files to magnetic tape. Recording and reproducing apparatus includes changer unit for selecting and carrying tape cassettes and accommodating magnetic tapes with predetermined recording areas, tape drive unit for loading tape cassettes and recording and reproducing magnetic tapes, hard disk drive unit having a buffer area for recording and reproducing data in the tape drive unit, and controller unit for managing recording areas of tape cassette magnetic tapes arranged in the changer unit as a continuously formed area. Storage level is set corresponding to remaining capacity of buffer area and remaining capacity of one BOF data area, or number of past access times to corresponding file in a file information table and final access time, etc. Based on storage level, control operations are performed. Frequently used file data can be selectively recorded to buffer or BOF data areas.
