Enhancing spin up and spin down times for data storage devices

A method for operating a data storage device, the method comprising:

• coupling a first spindle driver and a second spindle driver to a spindle motor, wherein the spindle motor comprises a plurality of windings, and wherein the first and the second spindle drivers are coupled in parallel to the plurality of windings;
• detecting a back electromotive force (BEMF) signal corresponding to one or more of a velocity and a position of the spindle motor;
• and
• controlling, based at least in part on detecting the BEMF signal, commutation of the plurality of windings of the spindle motor using the first spindle driver and the second spindle driver, wherein the first spindle driver and the second driver are used to:
• commutate the plurality of windings at or near the same time during one or more of a spin up routine, a spin down routine, and an at-speed routine of the spindle motor;
• or
• sequentially commutate the plurality of windings during one or more of the spin up and the spin down routines of the spindle motor.

One or more processing devices or components, comprising, individually or in combination:

• means for detecting a back electromotive force (BEMF) signal corresponding to one or more of a velocity and a position of a spindle motor of a data storage device, wherein the spindle motor comprises a plurality of windings, and wherein the data storage device comprises a first spindle driver and a second spindle driver coupled in parallel to the plurality of windings;
• and
• means for controlling commutation of the plurality of windings of the spindle motor using the first spindle driver and the second spindle driver, wherein the first spindle driver and the second spindle driver are used to:
• commutate the plurality of windings at or near the same time during one or more of a spin up routine, a spin down routine, and an at-speed routine of the spindle motor;
• or
• sequentially commutate the plurality of windings during one or more of the spin up and the spin down routines of the spindle motor;
• wherein the first and the second spindle drivers are controlled, based at least in part on detecting the BEMF signal.
