what is head linearizing in seagate drive

i am try to work hdd in termminal mode and i have using this commanc i4,2,22 i saw some times head linearizing what is the head linearizing

Head linearizing refers to specific adaptive parameters
Modern drives use special mathematical model to predict next HSA position after reading a servo mark. Predicting HSA position allows a drive to skip reading of one (or more) following servo marks but still maintain correct position thus improve data reading/writing performance. Linearizing parameters are crucial in that mathematical model.

Loosing original linearizing parameters might make the drive completely unresponsive and data on it unrecoverable.
