Chapter 1. Introduction
The IBM Ultrium Internal Tape Drive Models T200 and T200F are high-performance,
high-capacity data-storage devices that can be integrated into an enclosure, such
as a desktop unit, tape cartridge autoloader, or tape library. The tape drives are
designed to perform unattended backups, as well as retrieve and archive files.
Table 1 outlines the features of the Models T200 and T200F. Figure 1 is a front view
of the drive with and without a bezel.

The Ultrium Internal Tape Drive uses a data compression algorithm known as
LTO-DC (LTO Data Compression). A key difference between LTO-DC and previous
compression algorithms is that record boundaries and file marks are encoded as
control symbols in LTO-DC. LTO-DC detects them, but it will not recompress and
test them. Another difference is that LTO-DC allows switching between compression
and no compression within the data stream. This feature prevents the data from
expanding when the drive compresses random or encrypted data.
IBM offers device drivers for the Ultrium Tape Drive. Device drivers enable the drive
to interact with a variety of servers. To properly install an IBM device driver (if
1. 1 GB = one gigabyte or 1 000 000 000 bytes
2. 1 MB = one megabyte or 1 000 000 bytes
