    摘要: An optical data storage device having a substrate has guide ridges, or reverse grooves, in a concentric or spiral shape formed thereon, and disposed in a plane parallel to and disposed from the substrate surface. The device further has pits formed approximately midway between the guide ridges and disposed in the substrate and having bottoms below the plane of the substrate surface. A method for manufacturing the optical data storage device having both address pits and guide ridges is disclosed. A dual tone photosensitive material is applied to a substrate, exposed with a laser light source comprising two distinct wavelengths, and developed to provide a desired bipolar geometry thereon.
