摘要： A reading method for reading contents information with a laser from an optical disc including a plurality of recording layers includes positioning a focus position of the laser at a first recording layer and reading a first part of the contents information recorded in the first recording layer. If a first link information recorded in the first recording layer is detected, judging whether a first condition is fulfilled or not. If the first condition is fulfilled, positioning the focus position of the laser at a second recording layer and reading a first link destination information recorded in the second recording layer. If the first condition is not fulfilled, reading a second part of the contents information recorded in the first recording layer.

摘要： The present disclosure provides systems and methods associated with data storage using atomic films, such as graphene, boron nitride, or silicene. A platter assembly may include at least one platter that has one or more substantially planar surfaces. One or more layers of a monolayer atomic film, such as graphene, may be positioned on a planar surface. Data may be stored on the atomic film using one or more vacancies, dopants, defects, and/or functionalized groups (presence or lack thereof) to represent one of a plurality of states in a multi-state data representation model, such as a binary, a ternary, or another base N data storage model. A read module may detect the vacancies, dopants, and/or functionalized groups (or a topographical feature resulting therefrom) to read the data stored on the atomic film.

摘要： Optical information recording medium comprises: a plurality of recording layers 14, each of which undergoes a change in refractive index by irradiation with recording beam; and an intermediate layer 15 provided between recording layers 14. The recording layer 14 contains polymer binder and dye dispersed in the polymer binder, and at least in proximity to an interface (far-side interface 18) between the intermediate layer 15 and a recording layer 14 disposed adjacent to incident side of the intermediate layer 15 from which the recording beam enters the intermediate layer, the intermediate layer 15 has refractive index different from that of the recording layer 14. Glass transition temperature of the polymer binder is lower than melting point and decomposition point of the dye, and refractive index of the polymer binder changes by receiving heat generated when the dye absorbs the recording beam, whereby information is recordable in the recording layer.

摘要： An optical information recording medium having two or more information layers, wherein the irradiation of either the information layer with a laser beam converging thereon causes information signals to be recorded or reproduced; the nearer positioned information layer than the farthest information layer as viewed from the incidence side of the laser beam has a recording layer varying between two optically detectable states, and 0≦|Tc−Ta|/Tc≦0.1 where Tc is the transmittance of the nearer positioned information layer when the recording layer is in state (a) and Ta, the transmittance, when it is in state (b). This makes possible accurate accurately recording and reproduction of information onto and out of the farther information layer irrespective of whether or not any information is recorded on the nearer information layer.
