摘要： An optical recording medium comprising a cover layer (22) is desirable, especially for near field optical recording, but the high numerical aperture advantages of the system can be compromised by traditional cover layer materials, as the refractive index of these materials is too low. Significantly higher refractive index materials containing nanoscale particles can be used to solve this issue but a focused read/write spot can be deteriorated significantly due to scattering of light by the nanoscale particles. Use of a smoothing filter layer (24) restores spot quality.

摘要： An optical recording and reading system for use with an optical data storage medium (5) is described. The system comprises the medium (5) having a recording stack (9) and a cover stack (7) that is transparent to a focused radiation beam (1) which has a wavelength lambda in air. The cover stack (7) has a thickness dT. The recording stack (9) and cover stack (7) are formed sequentially on a substrate (8). An optical head (3), with an objective (2) having a numerical aperture NA and from which objective (2) the focused radiation beam (1) emanates during recording, is adapted for recording/reading at a free working distance dF of smaller than 50 µm from an outermost surface of said medium (5) and arranged on the cover stack (7) side of said optical data storage medium (5). When dT is smaller than 50

摘要： An optical recording device which enables high-density recording onto an optical recording medium, has a large degree of margin in depth of focus, has less risk of damage to the optical recording medium or an optical system, realizes stable recording and reproducing characteristics, and may be easily manufactured. The optical recording device includes an optical recording medium having a lubricant layer on the outermost surface on the incident light side, an optical system including an optical waveguide having a near-field lens or a minute aperture provided in contact with or close to the optical recording medium, and a light source. More preferably, an apodizer is provided on the side of the light source or the side of the near-field lens of a collimating lens located between the near-field lens and the light source. The optical recording medium is constituted by a multilayer body formed by stacking at least a lubricant layer, a recording layer, a dielectric layer, a reflective layer and a substrate in this order.
