3-6-1. Hi-MD3 setting
Preparation:
1. Perform calculation every item based on the data given by the
Hi-MD3 adjustment disc by referring to the following table.
(Round off the value in decimal place)
2. Convert the calculated value into hexadecimal number.
Note: The Hi-MD3 adjustment parameters vary depending on the disc,
and therefore use the parameters of the disc used when performing
the adjustment.
