Note:
Depending on the employed REC / PB head and test tape characteristics, there is a rare case that
the REC-EQ characteristics of this LSI can not be matched to the required characteristics because of
built-in resistors which determined the REC-EQ parameters in this case, please inquire the
responsible agent because the adjustment built-in resistor is necessary.
