Electronic apparatus including emissive display and transparent display and method of controlling same

According to various embodiments, a method for notifying of surrounding situation information by an electronic device may comprise the operations of: monitoring a value indicating a movement of the electronic device; determining whether a state of the electronic device is a stopped state, on the basis of the value indicating a movement of the electronic device; and acquiring surrounding situation information of the electronic device, which will be notified of to a user, when the state of the electronic device is a stopped state; and outputting the surrounding situation information.

Method, electronic device, and recording medium for notifying of surrounding situation information

A holographic data storage medium and an apparatus and method for recording/reproducing holographic data using the same. The holographic data storage medium includes a substrate; a holographic recording layer disposed on the substrate; and a cover layer covering the holographic recording layer. The holographic recording layer includes a data recording region including a plurality of data layers to which data is recorded, the data recording region in which interference fringes due to first and second beams are formed in different data layers in a depthwise direction; and a layer discrimination region for providing discrimination between the data layers.

Holographic data storage medium and apparatus and method for recording/reproducing holographic data to/from the same

An optical pickup of a holographic data recording/reproducing apparatus that emits light to a reflective holographic data storage medium in which a substrate, a reflection layer, a recording layer, and a cover layer are sequentially stacked, and receives the emitted light, the optical pickup including: a first light source unit to emit, during a recording operation, a signal beam having a first polarization and a reference beam having a second polarization perpendicular to the first polarization along the same optical path; and a main lens unit having a refractivity that varies according to a polarization of a passing light, so as to cause the signal beam to be reflected from the reflection layer then focused on a focal point, and to cause the reference beam to pass through the cover layer then be directly focused on the focal point.

Apparatus and method for recording/reproducing holographic data

The disclosure provides an electrophotographic toner including a binder resin; and a light absorber, wherein the light absorber includes a metal nanorod and a surfactant covering a surface of the metal nanorod.

Electrophotographic toner

An apparatus and method to record data on a holographic storage medium, the apparatus including: a light processing unit to record the data on the holographic storage medium using a reference beam and a signal beam, the light processing unit including a light modulator to modulate the signal beam; and a control unit to control the light processing unit to record the data on the holographic storage medium, wherein the light modulator modulates the signal beam so that an image formed on a surface of the light modulator is shorter in a radial direction that is a scanning direction of the reference beam than in a tangential direction that is perpendicular to the radial direction.

Apparatus and method for recording data on holographic storage medium

A method of recording holographic information and an apparatus for recording/reproducing holographic information. The method includes: forming an information layer by recording a hologram on a holographic recording layer of a holographic information storage medium; and fixing the information layer on which the hologram is recorded, by radiating light on the information layer.

Method of recording holographic information and apparatus for recording/reproducing holographic information

A hologram recording and/or reproducing apparatus, a hologram recording and/or reproducing method, and a hologram recording medium include a data processing unit to generate a data page which includes recording data and a reference page which includes predetermined patterns to prevent distortion of a signal from occurring when the data page is reproduced, and a light processing unit to record the data page and reference page on a hologram recording medium. The apparatus and method correct distortion and deformation that may occur in part of an image due to aberrations, enhancing compatibility between hologram recording and/or reproducing apparatuses.

Apparatus and method of recording/reproducing hologram and hologram recording medium

A method and apparatus for improving quality of a signal reproduced from a holographic storage medium in which a hologram is recorded by interference between a signal beam and a reference beam. The signal-quality improving method includes determining a page crosstalk value, which is caused in a page that is to be reproduced from the holographic storage medium by an adjacent page to the page that is to be reproduced, on the basis of on-pixel crosstalk values caused by a plurality of on-pixels of the adjacent page; and removing the determined page crosstalk value from a reproduced signal of the page that is to be reproduced. Since an interpage crosstalk that occurs when multiplexing recording in the holographic storage medium is calculated, and is removed from a reproduced signal, the quality of the reproduced signal can be improved.

Method of improving quality of signals reproduced from holographic storage medium and apparatus therefor

An optical recording medium in which interference patterns formed from interference between signal light and reference light are recorded as data and a recording/reproducing method and apparatus for the optical recording medium. The optical recording medium including at least a recording layer in which predetermined data is recorded, wherein a thickness of a portion of the recording layer is larger than a thickness of another portion of the recording layer, wherein data is recorded in the thicker region, and the additional information of a recording condition and/or a reproducing condition is recorded in the thinner region.
