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 mounted and movable in the direction of 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 unitary magnetic heads is constructed such that each of said heads has a predetermined inclination is to the respectively corresponding surface of recording media of the disks, preferably by forming a sloping surface on one end of each positioner.
Preferably, circuits for controlling the disk driving unit and the magnetic head, etc., of a disk drive are composed of a flexible printed circuit board to be contained in the disk enclosure having a base and cover.
