1
During continuous Seek, Read, or Write commands, an algorithm in the code will add latency as required to keep
the VCM motor from overheating;s seek performance will be impacted under this condition.
2
Defined as the time from power-on to the setting of Drive Ready and Seek Complete including calibration.
3
Defined as the time from power-on to when the full spindle rotational speed is reached.
4
Controlled unload at ambient condition.
