Ramp and HGA Cassette for Ramp Load Preparation
Agilent does not supply the ramp and HGA cassette for the ramp load. You need to prepare
them yourself. Agilent submits the information about the ramp and cassette dimensions to
make them in advance.
The ramp plate for 3.5 inch is already included in the ramp loading mechanism whose
thickness is 3 mm. You can use not only it with the ramp but also the ramp plate you made
with the ramp.
Figure H-3 shows the ramp plate dimensions for reference.
Figure H-3
Ramp Plate Dimensions
When the media is changed with the different thickness one, you can use the same ramp by
changing the ramp plate. The thickness of the ramp plate (X
4
) as shown in Figure H-4 is
defined the following equation.
CAUTION
If the media surface is higher than tip of the ramp (X
1
≤
0), the ramp hits the media.
CAUTION
If the dimension of the ramp you made is out of standard pattern, the ramp hits to the head,
HGA cassette or the HLM.
