Use only cassettes bearing the DDS symbol; you cannot
play audio DAT cassettes with these drives.
The DDS drive has a nominal capacity of 1.3 Gbytes on a 60-
metre cassette, with a sustained transfer rate of 183 Kbytes/
second.
The DDS-DC drive writing uncompressed data has a nominal
capacity of 1.3 Gbytes on a 60-metre cassette or 2.0 Gbytes
on a 90-metre cassette, with a sustained transfer rate of 366
Kbytes/second. At a data compression ratio of 4:1 the DDS-
DC drive has a nominal maximum capacity of 5.2 Gbytes on
a 60-metre cassette or 8.0 Gbytes on a 90-metre cassette; the
sustained transfer rate is increased by the same ratio. However,
the actual compression ratio and transfer rate achievable in
any particular case depend on the characteristics of the data
being compressed, and may be higher or lower than these
nominal figures.
Interpreting There are two LED (light-emitting diode) indicators on the
the LED drive's front panel. The Cassette in Place (green) and Drive
indicators Busy (amber) LEDs show the status of the drive:
