    摘要: A monolithic optical head facilitates reading and writing optical data on an optical recording medium. The optical head includes a monolithic substrate formed of an optically transparent material. The substrate has a first side and a second flat side opposing the first side. The first side includes a central region that has a curved surface to produce a lensing effect, and a peripheral region. The second flat side has a central portion opposing the curved surface to couple radiation from and to the curved surface through the substrate. The second flat side also has a peripheral portion opposing the peripheral region of the first side.
