ARCHIVE PYTHON DDS-DC OAT DRIVES---PRODUCT DESCRIPTION MANUAL
PREFACE
The Archive Python™ DDS-DC Digital Audio Tape (DAT) products---Models 4322NT, 4322NP, 4542NT,
4542NP, and 4352XP---are computer DAT drives with data compression. These drives also contain an
embedded Small Computer System Interface (SCSI) controller that provides a single-ended SCSI-lor
SCSI-2 interface.
The 4322 models are 3.5-inch, internal drives. The 4542 models designate 5.25-inch versions of these
3.5-inch internal drives, factory-built with a 5.25-inch bezel and mounting rails. The 4352 model is a self-
contained, external subsystem with power supply.
The 4-digit, 2-letter model numbers used for Python DAT drives are explained in Section 1.2.1. In this
manual, the short, 4-digit model designation (4322, for example) refers to all of the 4-digit,
2-letter models included in that model designation. For example, 4322 refers to the 4322NT and 4322NP
models.
This document gives you an in-depth look at the Python 4322, 4542, and 4352 DDS-DC drives. It is intended
for those familiar with basic tape drive technology or who are using or evaluating Python DAT data
compression drives.
This manual contains all the technical information pertinent to the internal and external Python DDS-DC
DAT drives except for details of the SCSI-l and SCSI-2 interfaces. Detailed technical information about the
Python SCSI interfaces (including a complete command summary) is contained in the Python Technical
Reference Manual (PIN 25356-002; DDS SCSI commands only) or the Python SCSI Manual (pIN
27298-001) available in 1992. However, Appendix C of this manual provides specific, important SCSI
information pertaining to data compression.
