Note: Seek time is defined as the time required for the actuator to seek
to a new position and settle on a track. It is measured by averag-
ing the execution time of a minimum of 1000 operations of the
indicated type as shown in Table 4-1. The seek times include
head settling time, but do not include command overhead time,
time spent reading or writing data, or rotational latency delays.
Unless otherwise specified, read/seek command settling criteria
is assumed.
