20090053616 | HOLOGRAPHIC RECORDING MEDIUM - A holographic recording medium is provided, which includes a recording layer. The recording layer comprises a radical polymeric monomer having an aromatic ring-containing group and a polymeric group, a polymer matrix having the aromatic ring-containing group, and a photo-radical polymerization initiator. | 02-26-2009 |
20090080314 | OPTICAL INFORMATION RECORDING/REPRODUCING APPARATUS AND ITS REPRODUCTION METHOD - An optical recording/reproducing apparatus includes an optical recording medium in which a holograms are recorded depending on an incident angle of a reference beam. The reference beam is irradiated to holograms while changing the incident angle to generate a reproduction light beam, and an image patterns are detected by an image pattern detector. The continuously output reproduction image patterns are temporarily stored in an image recorder, and the maximum value of reproduction light intensity is detected to generate a trigger signal. Depending on the trigger signal, an optimal image pattern is extracted from continuous reproduction image patterns, and thus, two-dimensional data is decoded. | 03-26-2009 |
20090080315 | OPTICAL INFORMATION RECORDING AND REPRODUCING APPARATUS AND METHOD OF OPTICALLY RECORDING AND REPRODUCING INFORMATION - An optical recording and reproducing apparatus according to the present invention utilizes an angle multiplexing interfering method to record multiple pieces of recording data on an optical recording medium. Recording conditions for the multiple recording and management information such as addresses are recorded in the same book according to a coaxial interfering method. In a reproduction mode, the management information is read from a hologram formed according to the coaxial interfering method. The management information is utilized to quickly read the recording data from a hologram formed according to the angle multiplexing interfering method. | 03-26-2009 |
20090195847 | HOLOGRAPHIC RECORDING MEDIUM - A holographic recording medium is provided, which includes a recording layer containing a three-dimensional crosslinked polymer matrix, a photo-radical generating agent, and a ring-opening polymerizable compound having a radically ring-opening polymerizable alicyclic structure. | 08-06-2009 |
20090231979 | OPTICAL RECORDING MEDIUM - An optical recording medium is provided, which includes a recording layer includes a polymer matrix, a polymerizable compound, a photopolymerization initiator, and a polymerization inhibitor. The polymerization inhibitor is formed of a compound which exhibits a molar absorption coefficient of zero to a light having a first wavelength and generates an acid or a base when exposed to an external stimulus other than the light having the first wavelength, thereby inhibiting the polymerization of the polymerizable compound. | 09-17-2009 |
20130077459 | OPTICAL DISC AND RECORDING AND REPRODUCING APPARATUS AND METHOD - In a recording and reproducing apparatus, an optical disc is rotated in a rotating direction and an optical system focuses a laser beam on the optical disc to form a beam spot on the optical disc. The optical system is provided with a scanner which deflects the laser beam along a radial direction of the optical disc in such a manner that the beam spot follows a first scan trajectory along a first direction crossing the rotating direction and a second scan trajectory along a second direction different from the first direction. A first data track with a sequence of recording pits along the first scan trajectory is formed and arranged on the optical disc. | 03-28-2013 |
