An optical data-storage medium comprises a base structure adapted to supply a peripheral surface with a medium adhered thereon, forming a data surface responsive to a light beam for providing optical signals corresponding to a plurality of data, wherein the plurality of data are arranged in a three dimensional pattern, most preferably, a plurality of helixes suitable for application of parallel processing of information. For this purpose, an optical data-storage apparatus is designed from a single platform to accommodate the optical data-storage medium rotatable therein about an axial line at a steady and constant speed, and to allow a plurality of optical heads each capable of providing a light beam jointly movable in a direction generally parallel to the axial line so as to simultaneously process a plurality of data bits at a time, i.e., in parallel. Thus, the optical data-storage apparatus can serve as high-performance secondary and tertiary storage, can allow a user to directly plug-and-play software from original data-storage media, and can process information in true multitasking and in parallel, increasing a data throughput by at least a 10-fold as compared with any conventional optical-disc drives.
