| media index
| Selects the media index from 0 to 63.
|
The sensitivity adjust defined by the copy of the media parameters where the copy is selected by the media index. When the host turns on the write laser in preparation for a plot, the laser power is specified by the sensitivity, the area of a swath and the drum speed.
|
|
| Theoretically the sensitivity should be a constant for every media but experience has indicated that the sensitivity is head-dependent. The NVS parameter med <media index> sensitivity defines the constant for the media and the NVS parameter med <media index> sensitivityadjust defines a head-dependent adjustment percentage.
|
|
| Note that the exposure head does not access the sensitivity adjust; this field is used only by the host. This media parameter is defined by the exposure head because the exposure ( determined by the combination of the laser power and the drum speed ) is head-dependent.
|
|
| The NVS parameter med <media index> laserpower is the original method used to define the laser power. The NVS parameter med <media index> sensitivity and med <media index> sensitivityadjust is the preferred method used to define the laser power. The sensitivity is independent of the area of a swath and the drum speed.
