Abstract
A system having a storage device including read/write heads for repositioning the read/write heads from a parking location to a position adjacent a surface of a magnetic disk, the storage device includes a spindle motor coupled to the magnetic disk, for accelerating the magnetic disk to at least a first number of revolutions per time period while the read/write heads are positioned at the parking location, and a solenoid control coupled to the read/write heads and to the spindle motor, for biasing the read/write heads towards the position adjacent the surface of the magnetic disk after the magnetic disk reaches the first number of revolutions per time period, wherein the spindle motor maintains a rotation of the magnetic disk at less than a second number of revolutions per time period before the read/write heads are positioned adjacent the surface of the magnetic disk, and wherein the spindle motor rotates the magnetic disk at a third number of revolutions per time period after the read/write heads are positioned adjacent the surface of the magnetic disk.
