ABSTRACT:
A magnetic disk drive comprises a plurality of disks that have a laminated arrangement with equally fixed spaces respectively, and are rotatably mounted, a disk driving unit that forces the disks to rotate, a plurality of positioners that are mounted movably in the normal direction to the tracks of the disks, respectively, a positioner driving unit that drives the positioners so that their respective ends can traverse the tracks, and a plurality of reproducing/recording elements e.g. unitary magnetic heads that are fixed on the respective ends of the positioners and perform read/write operations for the surfaces of recording media of the disks respectively. Each of the reproducing/recording elements is constructed such that each of the elements is adjustable in the rolling direction with respect to the respectively corresponding surface of recording media of the disks and adjustable in the distance from the respectively corresponding surface of recording media of the disks. Preferably, the method for assembling the disk drive includes the steps of locating the arras in a desired position, driving the sliding portions, detecting at least the degree of angle and relative distance between each one tip portion of the unitary magnetic heads and the respectively corresponding surfaces of recording media of the disks, and fixing the sliding portions and the guide portions to each other.
