    摘要： A system for reducing supply chain theft comprising a medium having a state-change material associated therewith that is activatable from a first detectable state to a second detectable state by an activating wave that is energetically different from the read- wave of the reader, thereby altering the medium from a limited read medium to a more open read medium; an activation unit operatively configured to direct activating waves to the optical medium such that one-way state-change material associated with such optical medium is activated from a first state to a second; and a verifier unit operatively configured to determine whether the one-way state- change material is its first or second optical state.

    摘要： A disk cartridge includes a lower case having an opening hole, an upper case for accommodating a disk together with the lower case, a shutter for opening and shutting the opening hole, and a close covering member closely contacting a non-information area at an inner circumference of the disk when the shutter is closed and being separated from the non-information area at an inner circumference of the disk when the shutter is open. Thus, when the shutter is closed, intrusion of dust is prevented so that the possibility of the information area of the disk being contaminated is lowered.

    摘要： A storage device (62) has a stator layer (26), an emitter layer (22), and a rotor layer (24). The rotor layer (24) has a plurality of data clusters (45), each having a substrate (34A, 34B) which is electrically isolated from the other data clusters (45) by a dielectric material (58). Another storage device (62) has a means for electrically isolating a plurality of data clusters (45), each having phase change media (36) coupled to a conductive substrate (34A, 34B), from each other. The storage device (62) also has a means for reading a differential signal (FIG. 7) from each of the data clusters (45) based on currents which flow from the phase change media (36) to the conductive substrate (34A, 34B) in each data cluster (45). A method of electrically isolating conductive regions on a micromover device is also provided.

    摘要： A write-once type optical disc and a method and apparatus for allocating a spare area on the write-once type optical disc are provided. The method includes allocating a data area on a recording medium of write-once type, and allocating a user data area and at least one spare area within the data area on the recording medium, the at least one spare area having a variable size, wherein a maximum recording capacity of the at least one spare area on the recording medium is less than a maximum recording capacity of at least one variable spare area on a rewritable type optical disc.

    摘要： In an ultra-high-density data storage device that includes at least one energy beam emitter (240) and a data storage medium (210) that itself includes an organic material (200), the organic material may include one or more Langmuir-Blodgett layers and may include a conductive polymer. Localized presence or absence of localized disorder in the Langmuir-Blodgett layers may be used to detect data bits formed in the data storage medium. The present or absence of one-dimensional conductivity in the organic material may also be used to read data bits formed in the data storage medium.
