height. The “R” reading can be calculated from the equations below.
NOTE
For standard disk thickness (0.8-mm), the micrometer reads direct Z-height (i.e, R=Z). For
non-standard disk thickness (e.g, 1.0-mm and others), the user must compensate the “R”
value by using the equations below.
In case of mm :
R = Read setting (mm)
Z = Z-height (mm)
T = disk thickness (mm)
In case of inch :
R = Read setting (inch)
Z = Z-height (inch)
T = disk thickness (inch)
11. Before attaching the cassette to be adjusted, slightly loosen the pin and the hexagonal
screws located on top of the cassette as shown in Figure C-6 (i.e, magnified view). To
adjust the pin screw use a 0.89-mm or 0.035” hex screwdriver, to adjust the hexagonal
screw use a 1.5-mm hex screwdriver.
NOTE
When working on step 10 DO NOT ATTACH the cassette on the Z-height adjustment tool
yet.
