Devices and Applications


To improve the density of information storage, this paper introduces a kind of annular binary filters with super-resolution, Several of these filters have been designed based on the genetic algorithm, the simulations demonstrate that the transverse gain of the filters can reach the value of 1.37. Thus they can remarkably decrease the recording spot size, which is helpful to improve the density of, information storage and to make the depth of focus, longer, and therefore they can avoid the mistake caused by the small undulation of the optical disk in the process of recording/reading the information.
