    摘要: An apparatus includes a write pole, a waveguide adjacent to the write pole, the waveguide having a truncated end, and a blocking layer positioned adjacent the truncated end and extending from one side of the waveguide across a portion of an aperture at the truncated end. The waveguide can be a solid immersion mirror or a channel waveguide.

    摘要: A method includes: fabricating a wafer having a plurality of layers, each including a feature of interest and a lapping guide positioned at a known location relative to the feature of interest, wherein the feature of interest and the lapping guide cross a common plane; lapping the wafer to the common plane to expose portions of the lapping guides; and measuring dimensions of the lapping guides and an offset of the lapping guides with respect to each other. An apparatus constructed using the method is also included.
