A family of drives uses similar parts in order to provide economies of scale and overlap of tooling necessary to manufacture the disk drives. The family of drives includes a full height drive (10) having multiple rotatable disks (11) and a head positioner arrangement (15) moving data heads relative to the disks. The head positioner arrangement includes an integrally formed head positioner having two coils (45) and (46) and a permanent magnet structure having two pairs of fixed substantially flat spaced permanent magnets, each coil extends through one pair of magnets. The half-height drive (20) includes fewer rotatable disks than the full-height drive, and also includes a head positioner arrangement (25) for mounting the heads relative to the disks. The head positioner arrangement (25) includes a pair of fixed substantially flat spaced permanent magnets manufactured to the dimensions of the magnets used in the full-height drive.
