Note: (1) Write Data and Write Clock timing shall be specified at the
output connector of the controller.
(2) The tolerance of TF includes the rotational speed tolerance and
the jitter of servo signal.
(3) NRZ Write Data issued from the controller is put in to the
RLL-Encoder and then written on the disk surface with
write-compensation.
