Dual actuators provide controlled two-degree-of-freedom (2-DOF) motion of a read/write head assembly over a stationary recording medium, using a dual actuator to find the recording track and provide head/disk relative motion. Fig. 1 shows an extremely small, dual-actuator four-link system 1-4 which serves to move a read/write head assembly 5 over a given area of a stationary magnetic storage disk 6. The read head is magnetoresistive to allow the data to be read independently of the head velocity (assuming, of course, that the velocity is known). The head assembly 5 is preloaded lightly against the recording medium 6 to allow high data-recording densities without excessive wear.
