Introducing the HP A3716A Autoloader

The HP A3716A autoloader combines a DDS-3 format drive with a changer

mechanism which accesses one of six cartridges in a removable magazine.

The DDS-3 (Digital Data Storage) format is the fourth generation of formats

based on DAT (Digital Audio Tape) technology. A single 125m DDS-3 cartridge

stores 24 GB of data using 2:1 data compression.

Note The autoloader is intended for use with five data cartridges and one cleaning

cartridge in the magazine, allowing one cartridge for each days use and the

ability to clean the tape heads when necessary. Use of more than one cartridge

per day is strongly discouraged.

Caution Use only an HP cleaning cartridge (part number 92283K) to clean the tape

heads. Do not use swabs or other means of cleaning the heads.

The HP A3716A can be used with HP 9000 Series 700 and 800 computer systems

and applications. Although optimum performance will be achieved with 125m

DDS-3 cartridges, the autoloader can read and write 120m DDS-2 cartridges in

DDS-2 format, and 60m and 90m DDS-1 cartridges in DDS-1 format. This

ensures backwards compatibility with earlier DDS-format drives and

autoloaders.

Note Use 125m DDS-3 cartridges for optimum performance.

Data Compression

By default, the HP A3716A compresses data before writing it to tape, using the

popular DCLZ algorithm. This achieves a compression ratio of typically 2:1.
