<p>A coil assembly (44) for use in an optical or a magneto-optical data storage system having a slider (37) and an optical assembly (40), includes a dielectric substrate (52). The coil (50) is either bonded to, or formed on the dielectric substrate, and terminates in two bonding pads. In one embodiment the dielectric substrate is flexible and is made of alumina. The coil is surface mounted on the underside of an optical assembly and/or a slider by means of available techniques, such as an adhesive. The coil assembly includes two tooling, alignment and handling holes, and an optical passage (100) defined at the center of the coil for allowing an optical beam to pass through. The coil assembly has compact, low mass, and high vertical magnetic field characteristics, and allows direct overwrite at a low flying height, with precise control of the focal plane of the optical assembly.</p> |
