Abstract: In a recorder for recording optical information in a plurality of recording areas of a holographic memory medium, a recording part records the optical information on a first recording area by multiple-recording; a determining part determines whether the recording in the first recording area has been completed; and a fixing part fixes the optical information on the first recording area in determining that the recording in the first recording area has been completed. The recording part records the optical information in a second recording area by multiple-recording in parallel with or after fixing the optical information in the first recording area when determining that the recording in the first recording area has been completed. Corresponding method and the medium used are also disclosed.

Abstract: An optical recording medium records data in three dimensions by recording a plurality of pieces of data in an area extending in a thickness direction of a recording layer thereof, and keeps a bit error rate low, that is, reduces noise, even when the recording layer is made thicker. The recording layer has a thickness of 200 ?m or more; contains at least one kind of a dye; and records data in three dimensions. An absorbance of the recording layer is 0.030 or less before data is recorded, at a wavelength longer than a wavelength of the recording light, at which the dye does not absorb light.

Abstract: A mechanism whereby a user can obtain a desired content via a communication network and a content distributor loses no profits. Identification information of each theater and each video content screened at the theater are registered. When a video content viewing request from a member is accepted, the theater which screens the content requested to be viewed is specified, the video content requested to be distributed is distributed to the member via a network, and an incentive for the video content distributed to the member is given to the theater which screens the video content requested to be viewed.
