    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), formed on a substrate (8). The recording stack (9) is suitable for recording by means of a focused radiation beam (1) with a wavelength lambda in air. The recording stack (9) has a first optical surface (6) most remote from the substrate (8). An optical head (3), with an objective (2) having a numerical aperture NA and from which objective (2) the focused radiation beam emanates (1) during recording, is (2) arranged on the recording stack (9) side of said optical data storage medium (5). The objective has a second optical surface (7) closest to the recording stack (9), and is adapted for recording/reading at a free working distance dF of smaller than 50 µm from the first optical surface (6). At least one of the first optical surface (6) and the second optical surface (7) is provided with a transparent hydrophobic layer (10) that has a refractive index n and has a thickness smaller than 0.5nun. In this way reliable recording and reading is achieved, specifically contamination build-up on the second optical surface (7) is prevented or counteracted.

    摘要: A UV curable coating composition for an ink-receiving layer that is required for ink jet printing and an optical recording medium having the ink-receiving layer formed by the UV curable coating composition are provided. The UV curable coating composition includes a (meth)acrylate monomer, a (meth)acrylate oligomer, N-vinyl-2-pyrrolidone, and inorganic and organic pigments. An ink-receiving layer formed by the UV curable coating composition shows excellent adhesion to substrates, ink absorption and adsorption, drying efficiency, and water resistance in ink jet printing. Therefore, high quality recording media can be formed.

    摘要: Systems and methods are described for inhibiting the readability of an optical media due to changes in a pseudo-reflective material that composes the optical media after the optical media has been exposed to air for a predetermined time. An optical media includes a data encoded component. At least a fraction of the data encoded component transforms form a substantially optically reflective state to a substantially optically non-reflective state as at-least-in-part a function of time from an initializing event. The systems and methods provide advantages because of low cost, limited content lifetime, avoidance of rental returns and minimum changes to existing manufacturing processes.
