The DDS-DC drive uses standard 60-metre or 90-metre digital
cassettes bearing the DDS symbol. The drive writes
compressed data by default, unless it finds uncompressed data
already on the cassette. The drive can also write uncompressed
data under software control. When reading a cassette, the
DDS-DC drive automatically distinguishes compressed and
uncompressed data and either decompresses it or passes it
through unaltered as appropriate.
Use only cassettes bearing the DDS symbol; you
cannot play audio DAT cassettes with this drive.
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 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.
