    摘要： An imprinting method is disclosed which involves irradiating a photo-curable imprintable medium in a flowable state on a substrate with radiation to initiate curing of the medium, after the irradiating, contacting the medium with a template to form an imprint in the medium, allowing the medium to substantially cure such that the medium is in a substantially non-flowable state while the medium is contacted by the template, and separating the template from the medium while the medium is in the substantially non-flowable state.

    摘要： The present invention relates to an optical record carrier for recording and/or information using a radiation beam in the UV wavelength range, in particular having a wavelength in the range from 230 to 270 nm, comprising a substrate layer (S) and an information stack (R) comprising an information layer (P) comprising a material for forming marks and spaces representing an information by irradiation of a UV radiation beam, a transparent cover layer (C) on top of the side of the said record carrier facing the incident UV radiation beam. The cover layer (C) is made of a cured resin composition being a silicon based reactive material, which achieves a high UV transparency required for the recording and/or reading of data. The optical record carrier may further comprise at least one additional information stack and at least one transparent spacer layer for separating the information stacks from each other, said spacer layer (SP) being made of the said resin composition.

    摘要： The invention relates to a method of manufacturing a master mold (1), which is used to manufacture an optical information disc, such as a CD or DVD. According to the method, a substrate (3) is provided with a photosensitive layer (5), which is subsequently irradiated by means of a radiation beam (7), which is focused to a scanning spot (11) on said layer by means of an optical lens system (9). A liquid, such as water, is supplied into a gap (53) present between the photosensitive layer and an auxiliary lens (59) of the lens system facing said layer. As a result, the size of the scanning spot is decreased and the information density of the information disc to be manufactured is increased. According to the invention, the liquid is supplied via a supply opening (69) which is positioned immediately adjacent the auxiliary lens (59), in a direction which, viewed from the scanning spot (11), is contrary to a direction (Z) wherein the substrate (3) is moved with respect to the lens system (9). Thus, the liquid supplied via the supply opening is transported immediately and exclusively into said gap (53), so that the amount of liquid to be supplied to fill the gap is limited. The supply opening is formed in a wall portion (65), which extends in an imaginary plane in which also a side wall (63) of the auxiliary lens (59) facing the photosensitive layer is present. As a result, a homogeneous Couette flow of liquid without air inclusions is obtained in the gap. This Couette flow does not cause any undesirable mechanical vibrations of the lens system. The invention further relates to a method of manufacturing an optical information disc, according to which method a master mold (1) is manufactured in a first step, and the information disc is manufactured in a second step by means of a replica process using said master mold. The invention further relates to a device (25) for the manufacture of a master mold by means of a method according to the invention.
