Notes:
1.
Spindle up to speed and actuator is track following.
2. Assuming random operation with a 30% seek duty cycle.
3.
Differential tranceivers transmitting and receiving.
4. Typical +12 Vdc currents are for sustained drive operation at 25° ambient temperature. Maximum +12 Vdc
currents (running and seeking) are for initial drive turn-on at 0° C ambient temperature.
5. Peak values shown are for occurrences greater than 5 milliseconds duration.
