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.
