摘要： An optical memory device and a method of recording/reproducing information by using the optical memory device. The optical memory device includes a substrate; a first barrier layer formed on the substrate; a quantum well layer; a second barrier layer; a quantum dot layer; and a third barrier layer. The quantum well layer has an energy band gap which is wider than that of the quantum dot layer, and the second barrier layer has an energy band gap which is wider than that of the quantum well layer, so that electrons in excitons which are generated in the quantum dot layer by light of a certain wavelength are captured by the quantum well layer to record information, and then, recorded information may be erased or reproduced by irradiating light of a certain wavelength to the optical memory device.

摘要： A servo controlling apparatus of a holographic information recording/reproducing system changes the foci of reference light and signal light in a depth direction of a holographic information storage medium to record information over a plurality of information layers. A servo control is changed from a normal servo operation to a between-movement servo operation while movement between information layers is made during a recording operation, and the servo control is changed back to the normal servo operation when the movement between information layers is completed. The between-movement servo operation maintains a servo control state that exists before the movement between information layers.

摘要： Disclosed is a 3-dimensional lens system adapted to reduce aberrations occurring as a left-eye image passing through a left-eye lens group and a right-eye image passing through a right-eye lens group are off-axially incident to the left-eye lens group and the right-eye lens group, respectively, and that is fabricated in a reduced size without using a reflection mirror. Also disclosed is an image capture device designed to be larger than an image so as to prevent a loss of the image.
