<div><p>This topic explains the importance of retention times for tape
|
||
|
|
cartridges.</p>
|
||
|
|
<p>For older tape cartridge types, the quarter-inch tape units run a retension
|
||
|
|
operation whenever a tape cartridge is loaded. <var class="varname">Retension</var> means
|
||
|
|
that the tape unit moves the tape to the end-of-tape position and rewinds
|
||
|
|
it to the beginning-of-tape position. The retension operation is part of the
|
||
|
|
load sequence. The tape unit also runs a retension operation if a tape cartridge
|
||
|
|
is in the tape unit when the door is closed.</p>
|
||
|
|
<p>When using MLR3-25GB, DC5010, MLR1-16GB, SLR100, and SLR60 tape cartridges,
|
||
|
|
the tape units run the retension operation only when necessary (as determined
|
||
|
|
by the tape unit) to maintain correct tape tension. The approximate retension
|
||
|
|
times are as follows:</p>
