摘要： A magnetic write head having a shield structure that provides both a leading shield and side shielding function. The magnetic shield is separated from the sides and leading edge of the write pole by a non-magnetic gap layer that has a non-uniform thickness. The non-magnetic gap layer is thicker near the leading edge and thinner at the trailing edge. This allows for increased side field gradient near the trailing edge of the write pole and decreased write field loss at the leading edge of the write pole.

摘要： The optical module includes an optical device mounting substrate 1 and an optical multiplexer/demultiplexer 2. One laser diode and at least one photodetector, which are positioned in the same plane, are mounted on the optical device mounting substrate 1. The optical multiplexer/demultiplexer is prepared by mounting a wavelength-selective filter and a mirror on the front and back surfaces of a transparent substrate. The optical device mounting substrate and the optical multiplexer/demultiplexer are mounted in a package 3 in such a manner that the optical device mounting surface and the filter surface are not parallel to each other. The optical module also includes a first lens, which is positioned near the laser diode or monolithically integrated with the laser diode, and a second lens, which converges light coming out of the optical multiplexer/demultiplexer toward an optical fiber.
