    摘要: A record carrier comprises three layers that react with each other when irradiated to form a mark on the record carrier. The three layers are separated by a two separating layers that prevent direct contact of the three layers thus providing stability to the record carrier. By irradiating one or both separating layers a region of those separating layers is destroyed or altered whereby an opening is created and the reaction of the layers adjacent to the separating layer is no longer prevented in that region and a mark can be formed. Since either one or two reactions can take place if one or both separating layers are destroyed or altered multiple reflection levels for a mark can be obtained, thus enabling multilevel recording where a single mark can represent more information compared to the situation where only two reflection levels can be obtained. The size of the resulting opening determines the size of the mark and can thus be used to create a very small mark allowing high density recordings.

    摘要: The present invention relates to a writable optical record carrier and a method of writing information on such a writable optical record carrier. The record carrier comprises a substrate carrying a recording stack which recording stack comprises, in this order, a recording layer and an absorption layer. The recording layer is essentially transparent for an incident light beam, and comprises material which changes its optical characteristics when heated. The first absorption layer converts the incident beam to heat thereby indirectly changing the optical characteristics of the recording layer material. The method comprises the steps: positioning a writing unit at a predetermined position, generating the beam by means of the writing unit, at least partially absorbing the beam in the first absorption layer, thereby producing a first spot of heat, conducting the heat towards the recording layer, and thereby locally changing the optical characteristics of the recording layer material.

    摘要: A recordable optical record carrier is provided comprising a recording dye layer, whereby said recording dye layer (111) comprises at least two organic dye materials being absorptive at different wavelengths. Further, a method for writing on such a recordable optical record carrier is proposed. According to the method marks representing the data are written via a writing laser beam at a first predetermined wavelength according to a writing strategy providing a channel bit length and a mark width appropriate for read-out by a beam of electromagnetic radiation at a second predetermined wavelength being different from said first predetermined wavelength.
