摘要： Methods and systems for laser etching of optical servo patterns on magnetic data storage media using two or more beams of laser energy produced from a single source of laser energy to produce a servo pattern on the magnetic data storage media. By using two or more etching beams, the time required to produce a servo pattern on the magnetic data storage media can be significantly reduced. Alternatively, each servo track in the servo pattern can be written more than once. The servo patterns thus formed can be read optically or they may be read magnetically using magnetic overwriting (if the servo pattern is formed in a magnetic coating on the media). In either case, the servo patterns are either permanently formed in the media when read optically, or they can be recreated after bulk erasing if they are provided using magnetic overwriting. In yet another alternative, the servo patterns may be read both magnetically and optically, with the magnetic and optical reading occurring simultaneously or sequentially.

摘要： An inspection system for viewing substrate or coated substrate features, wherein a directed light source is projected through a coated substrate onto a viewing surface such that features or irregularities in the substrate or in the coating of the coated substrate are displayed. The inspection system includes a projection system including a light source positioned adjacent the second major surface of the optically transmissive substrate, and a viewing screen positioned adjacent the first major surface of the substrate. The substrate is positioned in optical alignment along an optical path between the light source and the viewing screen such that irregularities in the coated top surface of the substrate can be visually observed on the viewing screen by a user. In one aspect the substrate is coated. Optionally, the directed light source is a laser scanner assembly.
