Abstract:

PCT No. PCT/NO96/00156 Sec. 371 Date Jan. 28, 1998 Sec. 102(e) Date Jan. 28, 1998 PCT Filed Jun. 24, 1996 PCT Pub. No. WO97/01166 PCT Pub. Date Jan. 9, 1997In 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.
