NOTES :
∗
The seek time is defined as the time for the actuator to seek and settle on the
desired track with the drive operating at nominal DC input voltages and
nominal operating temperature.
∗
The average seek time is determined by averaging the seek time for 1,000 seeks
of random length.
∗
The spin up time is the time elapsed between the supply voltages reaching
operating range and the drive being ready to accept all commands.
∗
The controller overhead is the time it takes to start a seek after the drive has been
selected.
∗
The average latency time is the time needed for another 1/2 revolution after seek
completion.
