General information for the 12/24GB 4mm Tape Drive
The 12/24GB 4mm Tape Drive is an internal streaming tape drive that provides medium
to high-capacity backup and archival capability as well as high data transfer rate. The
12/24GB 4mm Tape Drive uses NARROW bus (8-bit) architecture. Communications on
the SCSI bus can be either asynchronous or synchronous. The 12/24GB 4mm Tape
Drive is compatible with existing 2.0 GB and 4.0 GB 4 mm tape drives. The 12/24GB
4mm Tape Drive can be used as a boot device.
The tape drive is used primarily for:
