Introduction to Magazines and Cassettes

When purchasing DDS cassettes:

■

Always use cassettes labeled “DDS Media Recognition System” in the
drive. To use the full potential of the drive, make sure that they are
DDS-4 cassettes.

■

Never

use DAT cassettes because the media is not certified and they can

have a different specification that can cause them to jam in the
mechanism (see Chapter 1 for cassette specifications).
