Abstract

When data are stored in the tertiary storage devices, the tape drives shall read them from the tapes using the input/output (I/O) operations. Due to the long delay in exchanging tapes, it is inconvenient to exchange a tape for each read/write access operation. Thus, the entire object or file is accessed from the tape drives well before they are being used (Federighi & Rowe, 1994; Kienzle, 1995; Pang, 1997). These accessed objects are temporarily stored in the magnetic hard disks as secondary storage level.
