Abstract
A technique for method for positioning a magneto resistive head located upon an actuator arm onto a loading ramp of a storage unit. The technique includes the steps of operating a removable magnetic disk at a first number of revolutions per second, the magnetic disk having an outer diameter, positioning the magneto resistive head adjacent to the removable magnetic disk, reading data from the removable magnetic disk, detecting a reset signal, producing a back electro-motive force in response to the reset signal, biasing the magneto resistive head towards the outer diameter of the removable magnetic disk in response to the reset signal and to the back electro-motive force, reducing a number of revolutions per second for the removable magnetic disk from the first number to a second number of revolutions per second, the first number greater than the second number; thereafter using an energy storage unit to bias the magneto resistive head onto the loading ramp, in response to the reset signal.
