摘要:
An apparatus, method, and computer readable medium for writing data on a highly indestructible material is disclosed. A laser may write data on a first side of a highly indestructible material. The data may then be marked as non-rewriteable. The data may also be written on a second side of the highly indestructible material, with the second side being opposite the first side. The highly indestructible material may comprise a stainless steel storage medium.
摘要:
A recording medium (10) is provided with a left-handed material layer (1) having at least one of a permittivity and a permeability of a negative value, and having substantially periodically formed structures; and a recording layer (2) including island-shaped and substantially periodically arranged recording regions (22), and being laminated on the left-handed material layer (1). The structure period of the left-handed material layer (1) is equal to or is an integral multiple of the arrangement period of the recording regions (22) of the recording layer (2).

摘要:
A method of forming a patterned polymer layer on a substrate is provided. The method of forming a patterned polymer layer on a substrate includes forming a coating of a photo-curable composition on a substrate, imprinting the coating by embedding a stamper having a predetermined pattern in the photo-curable composition, irradiating the coating with light to cure the photo-curable composition, while the stamper is embedded in the coating, and separating the stamper from the coating on the substrate.
摘要:
Provided is a compound semiconductor nanoparticle that exhibits circularly polarized luminescence characteristics. CdS prepared inside a core of ferritin, which is a cage-like protein, exhibits a high circularly polarized luminescence (CPL). A wavelength of the circularly polarized luminescence (CPL) can be controlled by laser irradiation, thereby enabling utilization of the compound semiconductor nanoparticle in the field of bionanotechnology, for example, in creating a WORM (Write-Once Read-Many times) memory. As the cage-like protein, which is a protein with a cavity formed therein, a protein belonging to the ferritin protein family, such as apoferritin, or a recombinant thereof can be used.

摘要:
A method for determining layers in a recording medium having a plurality of layers for the recording and reproduction of information using light irradiation. Each of the plurality of layers includes an emboss portion and a wobble region having wobbles of a predetermined frequency. Layer determination is carried out based on the ratio of the amplitude of a wobble signal obtained from the wobble region to the amplitude of a reproduction signal from the emboss portion.
