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 exec ut ion time of a minimum of 1000 op erat ions of the
indicated type as shown in Table 4-1. The seek times include
head s e ttl ing time, but do not inc l ude command o v erh ead t ime,
time spent reading or writing data, or rotational latency delays.
Unless otherwise specified, read/seek command settling criteria
is assum ed.
