How to specify read or write on inner track or outer track of the HDD?

["shadow_lin" <shadow_lin@xxxxxxx>]

Hi list,
	Is there a way to specify fio to read or write on inner track or outer track of the HDD?
         I want to test the difference of performance of HDD between accessing inner track and outer track.
         Thanks
