Introduction
This chapter provides general, physical, and functional descriptions of the TSZ07 Tape Drive
and provides illustrations showing the major parts of the drive.
1.1 General Description
The TSZ07 Tape Drive (shown in Figure 1–1) is a high-capacity streaming, nine-track, reel-
to-reel, half-inch magnetic tape drive unit with the capability of reading or writing in one
of two selectable recording densities. The drive is designed for the interchanging of data,
archival storage, software distribution, online transaction management, and the backup of
small and large computing systems. Connection to external computer equipment is by way
of an onboard Small Computer System Interface (SCSI 2) which conforms to the American
National Standard Institute (ANSI) specification X3T9.2/89-042. The TSZ07 Tape Drive
comes with either a single-ended or differential-ended SCSI interface (see to Table 1–1).
Single-ended drives allow a total SCSI bus length of 6 meters; differential-ended drives allow
a total SCSI bus length of 25 meters.
