An optical recording medium includes a substrate and a plurality of recording layers laminated via at least intermediate layers, at least one of the recording layers other than a recording layer farthest from a light incidence plane among the plurality of recording layers containing at least one metal M selected from a group consisting of Ni, Cu, Si, Ti, Ge, Zr, Nb, Mo, In, Sn, W, Pb, Bi, Zn and La and an element X which can combine with the metal M upon being irradiated with a laser beam for recording data, thereby forming a crystal of a compound of the element X with the metal M. According to the thus constituted optical recording medium, it is possible to record data in and reproduce from a farthest recording layer from a light incidence plane in a desired manner and it is possible to record data in and reproduce from recording layer(s) other than the farthest recording layer from the light incidence plane in a desired manner.

An optical recording medium includes a substrate, a light transmission layer and a recording layer formed between the substrate and the light transmission layer, the recording layer containing at least one simple substance of a metal element M selected from a group consisting of Zn and La and an element X selected from a group consisting of S and O which can combine with the metal element M to form a compound of the element X with the metal element M and the optical recording medium being constituted so that upon being irradiated with a laser beam for recording data, a crystal of the compound of the element X with the metal element M is formed and grows to form a crystal region thereof. According to the thus constituted optical recording medium, a reproduced signal having a good C/N ratio can be obtained when data recorded in the recording layer are reproduced.

摘要:
An optical recording/reproducing method and an optical recording medium capable of performing excellent optical recording with a simple structure in a recording layer made of environmentally friendly materials. The optical recording medium has a recording layer on a substrate. The recording layer has a pair of dielectric layers of which states are altered by a laser beam that is an energy beam of which intensity is modulated according to information to be recorded. This recording layer also has a assisting material layer sandwiched by these dielectric layers. The assisting material layer includes an element selected from Sn, Ti, Si, Bi, Ge, and C as a principle component, while the dielectric material as a base material for the dielectric layers is any one of ZnS, SiO2, AlN, and Ta2O5.

An optical recording/reproducing method and an optical recording medium capable of performing excellent optical recording with a simple structure in a recording layer made of environmentally friendly materials. The optical recording medium has a recording layer formed on a substrate and made of a mixture of a recording assist material and a dielectric material. A laser beam of which intensity is modulated in accordance with information to be recorded is irradiated onto this recording layer to cause a state change in the recording assist material and/or the dielectric material. The information can be recorded by changing optical characteristics thereof such as reflectivity. The recording assist material includes an element selected from Sn, Ti, Si, Bi, Ge, and C as a principle component, while the dielectric material as a base material for the dielectric layers is at least one of ZnS, SiO2, AlN, and Ta2O5.

摘要:
A remote file server managing a remote storage device and a local file server managing a local storage device are coupled to a communication network (e.g. the Internet). The local file server (A) replicates a file in the local storage device to the remote file server and, (B) if a first condition is satisfied, manages the replicated file which is the file from which the data is replicated as a migration target file. The local file server, even if the (B) is completed, does not delete the migration target file from the local storage device and, if the second condition is satisfied, deletes the migration target file from the local storage device.
摘要:
The present invention enhances user usability by storing more files close to the user. A replication processing part 3A creates a replica of a prescribed file, which is in a first file management apparatus, in a second file management apparatus. A single instance processing part 3B selects as a duplicate data removal target another prescribed file in the first file management apparatus in accordance with a first prescribed condition, and converts the selected other prescribed file to a reference-source file, which references data of a prescribed reference file. A stubification processing part 3C selects a stubification candidate file, which constitutes a target of a stubification process, in accordance with a second prescribed condition, and executes stubification processing with respect to the stubification candidate file in accordance with a third prescribed condition.
摘要:
A storage system comprises a second NAS storage apparatus and a third NAS storage apparatus for migrating an object managed by a first NAS storage apparatus. The second NAS storage apparatus comprises a processor and a storage medium, which is able to store data. The processor of the second NAS storage apparatus, with respect to an object for which a migration from the first NAS storage apparatus has started, stores path information of the object in the first NAS storage apparatus after including the path information in object management information, in the storage medium prior to migrating the object entity to the third NAS storage apparatus. Also, the processor, after receiving the object entity from the first NAS storage apparatus and migrating the object entity to the third NAS storage apparatus, stores the third NAS storage apparatus path information to the object entity in the object management information, and reflects the management information in the third NAS storage apparatus.
