TLZ06 Cassette Tape Drive Product
Description
1.1 Overview
The TLZ06 cassette tape drive provides you with high capacity, off-line data
storage. Depending on the 4 mm data cassette tape used, the unit can typically
store:
Tape Type (see NOTE 1.) No Compression Compression
TLZ04-CA (60 m) 1.3 GB 2.6 GB
TLZ06-CA (90 m) 2.0 GB 4.0 GB (see NOTE 2.)
NOTE
1. The TLZ06 is compatible with TLZ04 (60 m) cassette tapes in the
noncompressed mode only.
2. The 4.0 GB measurement is typical for a 2-to-1 data compression
ratio, but the actual ratio is dependent on the data.
The maximum time to backup (read or write) on a TLZ06 cassette tape in a
continual (streaming) mode is system dependent. The efficient use of streaming
mode is determined by your operating system. Please refer to your system
software documentation.
TLZ06 Cassette Tape Drive Product Description 1–1

1.1.1 System Support
As of this printing, the TLZ06 drive is supported by VAXstation systems and
DECstation systems. Your particular system must have a standard SCSI
(small computer system interconnect) port, or a KZQSA (Q–bus to SCSI
adapter).
VAXstation systems can use the VMS or ULTRIX operating systems.
DECstation systems use the ULTRIX operating system. Consult with your
Digital sales support person for operating systems supporting this device.
1.2 Design Features
The TLZ06 cassette tape drive uses state of the art technology. The TLZ06
cassette tape drive’s design incorporates both digital data storage (DDS) and
digital audio tape (DAT) recording technologies.
1.2.1 What is Digital Audio Tape (DAT)?
Digital audio tape (DAT), such as TLZ06 cassettes, takes advantage of the
TLZ06 tape drive’s helical scan technology. This technology allows data to
be stored diagonally on tape. As such, DAT allows more data to be stored on
tape. Also, DAT recording minimizes ‘‘crosstalk,’’ providing you with more data
integrity.
1.2.2 What is Digital Data Storage (DDS)?
Digital data storage (DDS) uses a recording format that supports the use of
digital audio tape for computer applications. The DDS/DAT format allows
you to back up 2 gigabytes of data in approximately 3 hours minimum with
no operator intervention. In addition, this format has three levels of error
correction, which ensures high data integrity.
NOTE
Use of Non-DDS media may result in degraded drive performance and
is not recommended by Digital Equipment Corporation.
