Abstract:
A data carrying medium for use with a method for optical data storage with high density, comprising:a number of flat, thin memory components in the form of cards or disks which form a stack of memory components;each said memory component comprising at least one information carrying layer;each said memory component comprising at least one data carrying area, each said data carrying area including at least one said information carrying layer for optical storage of data;the memory component outside each said data carrying area comprising at least one optically transparent area;each said transparent area having a geometric shape corresponding to a shape of a data carrying area; andeach said memory component in the stack of memory components being alignable with each other to form a window area and being displaceable relative to other memory components to permit reading and writing through said window area when said optically transparent area of said memory components are aligned with each other without separating physically each said memory component from said other memory components.
