DDS Logo Media
To identify computer-grade DDS media easily, look for the DDS logos (See
Figure 1-2), including
!
DDS-1,
"
DDS-2,
#
DDS-3, and
$
DDS-4. These
indicate that the media meets the DDS specifications laid down by the ECMA,
ISO/IEC and ANSI standards.

The Media Recognition System (MRS) enables drives to identify DDS-grade
media. DDS MRS cassettes have a series of stripes on the transparent leader at
the beginning of the cassette. The drive can be configured to treat non-MRS
cassettes as write-protected. In other words, the drive is only allowed to read
non-MRS cassettes, not write to them.
