NOTES: ∗ Seek time is defined as the time from the receipt of a read, write or seek command until
the actuator has repositioned and settled on the desired track with the drive operating at
nominal DC input voltages and nominal operating temperature.
∗ Average seek time is determined by averaging the time to complete 1,000 seeks of
random length.
∗ Average latency is the time required for the drive to rotate1/2 of a revolution and on
average is incurred after a seek completion prior to reading or writing user data.
∗ Spin up time is the time elapsed between the supply voltages reaching operating range
and the drive being ready to accept all commands.
