Title: MAGNETIC RECORDING DEVICE USING CIRCUMFERENTIALLY OFFSET HEADS WITH DOUBLE SIDED MEDIA
Abstract:
A pair of oppositely-disposed stabilizer devices (18, 18') support opposed magnetic heads (24, 24') for interfacing with opposite sides of a rotating magnetic disk (6). Each stabilizer device includes a block (20, 20') with an opening (22, 22') through which the magnetic head protrudes for engagement with a respective side of the disk. An air bearing surface (26, 26') on each block surrounds the opening adjacent the disk for generating coupling forces that deform the disk out of its nominal plane (40) on opposite sides thereof and into intimate contact with the transducing gaps (32, 32') on the respective heads. The stabilizer devices are positioned in relation to separate radii (r1, r2) depending from the center (c1) of the drive spindle (13) so that a circumferential offset (o1) is established that permits substantially separate interaction of the air bearing surfaces with the disk.
