Abstract
A pair of oppositely-disposed stabilizer devices support opposed magnetic heads for interfacing with opposite sides of a rotating magnetic disk. Each stabilizer device includes a block with an opening through which the magnetic head protrudes for engagement with a respective side of the disk. A flat, circumferential air bearing surface on each block surrounds the opening adjacent the disk for generating coupling forces that deform the disk out of its nominal plane on opposite sides thereof and into intimate contact with the transducing gaps on the respective heads. The stabilizer devices are positioned in relation to separate radii depending from the center of the drive spindle so that a circumferential offset is established that permits substantially separate interaction of the air bearing surfaces with the disk.
