摘要: In an optical data storage medium with a storage area formed from a transparent, homogenous base material and with a number of optically active structures at one side of the storage area, the optically active structures are diffractive optical elements which can focus a beam of light incident on the storage area on to one or more points in the storage area and/or a redirected beam of light or emitted light radiation from this or these points on to a point outside the optical storage medium. During writing/reading of data in the storage medium, the diffractive optical elements are used for focusing the write/read beam in order to generate a data carrying structure or read data stored in such a data carrying structure, respectively. By exploiting the special optical properties of diffractive optical elements, it is possible to achieve parallel writing/reading of data, possibly in several parallel storage layers in the optical storage medium or randomly distributed therein, the optical storage medium thus providing a genuine volumetric storage and a corresponding genuine volumetric accessing of the stored data.

摘要: In a method for optical data storage with high density, there are employed as the data carrying medium a number of flat, thin memory components in the form of cards or discs. Two or more of the memory components are arranged in a stack, thus enabling each individual memory component to be manoeuvred in relation to the other memory components by means of a manoeuvring device, and a given memory component is moved in relation to the other memory components in the stack in order to write or read data in a data carrying area on the memory component, which can be addressed optically during the write or read operation without interference from the other memory components. A data carrying medium for use with the method for optical data storage with high density comprises a number of flat, thin memory components in the form of cards or disks. A memory component comprises one or more data carrying areas, each data carrying area being capable of including one or more information carrying layers and arranged for optical storage of data. Furthermore, outside the data carrying area(s) the memory component comprises one or more optically transparent areas or windows.
