ABSTRACT:
A data storage device includes a printed circuit board that serves as a base of the data storage device. A data storage medium is rotatably mounted upon a first shaft that extends from the printed circuit board. A first magnet is installed upon a first surface of the data storage medium for generating a first magnetic field. A first electrically conductive coil is formed within the printed circuit board for generating a second magnetic field in response to an application of electrical current. The first and second magnetic fields interact to produce rotation of the data storage medium about the first shaft. An actuator is rotatably mounted upon a second shaft that extends from the printed circuit board. A magnetic head is installed on a first end of the actuator for reading data from and writing data to the data storage medium. A second magnet is installed on a second end of the actuator positioned opposite to the first end for generating a third magnetic field. A second electrically conductive coil is formed within the printed circuit board for generating a fourth magnetic field in response to an application of electrical current. The third and fourth magnetic fields interact to produce rotation of the actuator about the second shaft, thereby enabling the magnetic head to read from or write data to the data storage medium.
