Selectable Duty for Silent Seek Sound

   Disclosed is a method to make actuator moving (seek operation)
sounds lower in a Hard

     Disk Drive (HDD). That is realized by changing the duty of
the seek operations.

     And the duty must be selectable by a user who demands a silent
HDD for comfortable
surroundings.

   Sounds comes mainly from the seeking operation. Then reducing
the duty of the
operation makes the noise level lower and also the performance
lower. But it is difficult
to tell the proper noise level. It depends on the user and
the environment.

     It is better to be selectable on the duty for the user. One
user may set the full duty for
the performance and some another user may set the lower duty
for the silent.

   For that purpose, the HDD supports the command that delay the
complete timing of
write and read command. The value of the delay is selectable.
And the preference is
stored on a disk.
