8.5.1 Unload Forces, Placement, and Timing
Figure 8-3. Tolerances for Cartridge Insertion and Extraction (Alternate Ejection Scheme)
Eject Distance
When ejecting a cartridge from the drive using the ejection scheme for libraries,
the distance the cartridge travels at the time of ejection is shown in Figure 8-3.
Cartridge Extraction Force
Limit the extraction force (applied by the picker) to 4.5 lbs (maximum). More
force than that will bend the pin on the takeup leader (if the leaders fail to
unbuckle).
Extraction Velocity
The extraction velocity must be in the range: 0 < velocity ≤ 1.5 inch/sec.
*
* The minimum distance the cartridge travels when ejected from the drive.
† The distance the cartridge must be allowed to freely eject without interference.
