摘要： For irradiating a layer a radiation beam is directed and focussed to a spot on the layer, relative movement of the layer relative to the lens is caused so that, successively, different portions of the layer are irradiated and an interspace between a surface of the lens nearest to the layer is maintained. Furthermore, at least a portion of the interspace through which the radiation irradiates the spot on the layer is maintained filled with a liquid, the liquid being supplied via a supply conduit. At least a portion of the liquid fills up a recess through which the radiation irradiates the spot.

摘要： A non-leaching adhesive system and its use in a liquid immersion objective for immersion-writing of masters for optical discs are disclosed. The adhesive system comprises at least one monomer, selected from among the group of acrylate and methacrylate monomers, allylic monomers, norbornene monomers, hybrid monomers thereof, containing chemically different polymerizable groups, and multifunctional thiol monomers, provided that said thiol is used in combination with at least one of said non-thiol monomers; and a polymerization initiator. At least one of said monomers, not being a thiol, is provided with at least two functional polymerizable groups to obtain a crosslinked polymer network. The polymerization initiator is preferably an initiator that can be activated both thermally and with UV radiation. The adhesive system may further contain a reactive diluent. Further the use of the present adhesive system in mounting a liquid immersion objective is disclosed.

摘要： The invention relates to a record carrier comprising a train of marks and lands ( 14, 15, 23 ), which has a plurality of marks comprising shortest marks ( 1 ) and other marks ( 2 ) and a plurality of lands between said marks in a direction of said train of marks and lands comprising shortest lands ( 28 ) and other lands ( 27 ), said train of marks and lands ( 14, 15, 23 ) having information read by applying a light beam, and a land area not being part of said train of marks and lands. To provide a record carrier with an improved modulation of all marks without sacrificing tangential density and to further provide a record carrier with a reduced or substantially no asymmetry, it is proposed that said shortest marks ( 1 ) and leading and trailing edges ( 3 ) of said other marks ( 2 ) have a width larger than that of a central mark section ( 4 ) between said leading and trailing edges ( 3 ) of said other marks ( 2 ) and that said lands between said marks ( 19 ) in said direction of said train of marks and lands ( 15 ) have a reflectivity lower than that of said land area. The invention further relates to a method and a device for manufacturing such a record carrier.

摘要： A device for directing radiation to a layer (1) is described. The device includes a first optical element (L1) for focusing a first radiation beam (B1) originating from a first radiation source (S1) onto said layer, a second optical element (L2) for focusing a second radiation beam (B2) originating from a second radiation source (S2) onto said layer. The wavelengths of the radiation from said first and said second radiation source are different from each other. The first and second optical element are jointly movable with respect to said radiation sources, wherein the focal points of the two radiation beams at least substantially coincide with various movements of the first optical element and the second optical element with respect to the radiation sources. The second optical element (L2) has an aperture (A2) which allows optically undisturbed passage of the first radiation beam (B1). In this way a compact and light configuration of L1 and L2 is achieved as well as an improved radiation beam quality. Further an apparatus comprising such a device and a method using such an apparatus are disclosed.

摘要： The present invention relates to a data medium to be read out by a focused reading beam having a predetermined wavelength. The data medium implements a new concept of generating a reference beam, by comprising a reference beam interface, which, in the propagation direction of the impinging reading beam, is arranged either in front of a data layer with a pit-and-land structure, and is partially reflective while the pit and land interface sections are fully reflective for the reading beam. Or the reference layer is arranged behind the first and second reflective interface sections, and is fully reflective while the pit and land interlace sections are partially reflective for the reading beam. The data medium of the invention has a number of between 5 and 20 channel-bit cells contained in a reference area A-ef defined by the square of the ratio between the reading beam wavelength WL and the numerical aperture NA of an optical system focusing the reading beam. The ratio between the sum of the areas of all pit interface sections and the sum of the areas of all land interface sections of the pit-and-land structure is between 0.4 and 0.6.

摘要： In order to distinguish a duplicated record carrier from an original record carrier, a pattern is included in a ROM type record carrier. The pattern is oriented perpendicular to the reading direction of the record carrier. During illegal duplication the spatial relationship is disturb which can be easily detected. The patterns can be read out simultaneously by the same single read-out spot by including both patterns within the diameter of the optical spot, thus guaranteeing that the read-out patterns are actually still spatially close together.
