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.

Figure 1-2. DDS Logo Media
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.
