Abstract
An electromagnetic disk drive system including a rigid disk and electromagnetic read/write bead structure and elongate flexure structure which cooperatively offer unique features and performance in the head/disk interface region. The head structure and flexure structure, in one general form of the invention, are unitary and integrated and in another general form are articulated. Both forms of the invention perform with substantially continuous contact with the recording surface of the disk, and both are characterized by an overall effective mass no greater than about 1.5-milligrams. <IMAGE>
