OAT Cassette Temperature Limits
If you expose DAT cassettes to temperatures outside
the operating limits, the temperature of the cassettes
must be stabilized before they are used. To stabilize the
temperature of a DAT cassette, leave the cassette in the
operating temperature for a length of time equal to the
time the cassette was outside the limits, up to a maximum
of eight hours (refer to "Environmental Requirements" at
the end of this chapter).
Media Warning and Tape Wear
The read/write head in your DAT drive should be cleaned
with a cleaning cassette after every 10 hours of use
to maximize data integrity and prolong the life of the
read/write head in your DAT drive.
The DAT drive monitors tape wear. The DAT cassette
and drive busy lights flash a media warning when the
tape is nearing the end of its useful life, or when the tape
heads are dirty (refer to MEDIA WARNING in Table 5-3).
Perform the following sequence when the busy lights
indicate a media warning:
1. Clean the tape heads with the cleaning cassette (follow
the instructions on the cleaning cassette case).
2. Repeat the operation that was being performed when the
media warning occurred.
3. If the media warning is not repeated, the tape heads
were dirty and normal use of the DAT cassette can be
resumed.
If
the media warning is repeated, perform the
following steps:
a. Copy the data from the DAT cassette onto a hard disk
drive.
