Data storage device employing spindle motor driving profile during seek to improve power performance

A data storage device comprising:

• a head actuated over a disk;
• a spindle motor configured to rotate the disk;
• a ramp;
• and
• control circuitry configured to:
• rotate the spindle motor at a rotation speed proximate an access speed when accessing the disk, wherein the rotation speed deviates from the access speed by a maximum jitter error when accessing the disk;
• increase a rotation speed of the spindle motor above the access speed by at least twice the maximum jitter error to increase a kinetic energy of the spindle motor;
• and
• use at least part of the increase in kinetic energy of the spindle motor to unload the head onto the ramp.

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

• rotate a spindle motor at a rotation speed proximate an access speed when accessing a disk, wherein the rotation speed deviates from the access speed by a maximum jitter error when accessing the disk;
• increasing a rotation speed of the spindle motor above the access speed by at least twice the maximum jitter error to increase a kinetic energy of the spindle motor;
• and
• using at least part of the increase in kinetic energy of the spindle motor to unload a head onto a ramp.
